Lake Vico (VT)

Lake Vico is the great volcanic body of water of the Tuscia of Viterbo, enclosed in a caldera among the Monti Cimini, in the province of Viterbo. You get there from Via Cassia by turning onto Cassia Cimina. The practical reference point is the Visitor Center of the Lake Vico Regional Nature Reserve, on S.P. 1 Cassia Cimina at kilometer 12, in the territory of Caprarola (VT). Entry to the reserve is open and free: you don't pay a ticket to enter the protected area. What you do pay, if anything, is parking at the lakeside beach clubs in summer and any guided visits. By car from Rome you take Cassia as far as Ronciglione or the turnoff for Caprarola and from there you descend into the basin. By public transportation you reach Viterbo or Ronciglione by train or bus and continue overland, because the lake has no station of its own. The swimming season runs roughly from June to September, at the equipped beach clubs. For the updated hours of the Visitor Center, guided visits and excursions it's best to contact the managing body before leaving. There are no closing hours for the landscape: the reserve is toured by day, the trails are tackled with suitable footwear and water in tow, because the refreshment points are concentrated on the shore and not along the forest routes.

If you are looking for the general overview of the protected areas of Lazio to put on the calendar for a day trip, you'll find a starting point in the page devoted to the Lake Vico Nature Reserve and in the local tourist attractions.

Where Lake Vico (VT) is and how to get there

Lake Vico occupies the floor of a volcanic basin in the Monti Cimini group, north of Rome and a few kilometers southeast of Viterbo. The surface of the water is at 507 meters above sea level, a fact worth keeping in mind because it makes this basin one of the highest lakes in Italy among those of significant size. Around the water two peaks rise to close the scene: Monte Venere, 851 meters, which juts out like a wooded peninsula into the basin, and Monte Fogliano, 965 meters, the most imposing summit of the western rim. A little further north stretches Monte Cimino, the highest peak of the entire Cimini chain, which gives its name to the whole Cimini region.

By car to Lake Vico (VT)

The main road is Via Cassia. From Rome you go north up to Ronciglione or the turnoff for Caprarola, then you take Cassia Cimina, the S.P. 1, which crosses the rim of the caldera and descends to the shore. Coming from Viterbo you follow the same route in the opposite direction. The most beautiful scenic route is the S.P. 39 del Lago di Vico, the road that runs high on the northwest slope and gives a view from above over the basin. Practical advice: on summer weekends the parking areas near the beach clubs fill up early, so it's best to arrive in the morning and not at noon.

By public transportation to Lake Vico (VT)

Lake Vico is not served by a railway station on the shore. The reference hubs are Viterbo, reachable from Rome by regional train and by the Roma Nord railway, and Ronciglione, served by intercity bus lines. From these towns you continue by local bus or, much more conveniently, by car. Without your own vehicle the upper part of the trails is hard to reach, because the starting points of the excursions are spread along the provincial roads that circle the basin.

The Visitor Center of the Lake Vico Nature Reserve

The reference point for information, trail maps and guided visits is the Visitor Center of the managing body, on S.P. 1 Cassia Cimina at kilometer 12, in the territory of Caprarola. It is here that it's best to ask which routes are open, what the swimming situation is in the current season and whether guided excursions are scheduled. Updated hours and contacts should be checked on the body's official site before the visit, because they change with the seasons.

What Lake Vico (VT) is: a lake inside a volcano

Lake Vico is not just any lake: it is what remains of an extinct volcanic system. The basin that now holds the water is a caldera, that is the large depression formed when the magma chamber emptied and the summit of the volcano collapsed on itself. Scholars define it as a polycentric caldera, because the activity was not concentrated in a single crater but in several eruptive vents that alternated over time. The most intense volcanic phases fall between about 400,000 and 93,000 years ago. When the activity ceased, around 90,000 years ago, the depression began to fill with rain and meltwater accumulated in the cold phases of the Quaternary. The result is the mirror of water we see today.

Monte Venere, the volcano's last breath

The wooded cone that enters the water, dividing the basin, is Monte Venere. It is not just any hill: it represents one of the last manifestations of volcanic activity, a cone that grew inside the already formed caldera, together with the Pantanello flow. Looking at it from above you understand the structure of the volcano better than from any sign: the outer caldera, the younger cone in the center, the water filling what the fire left behind.

How the volcano of Lake Vico (VT) formed

The geological history of this place can still be read in the landscape, if you know what to look at. The Vico volcano was not born all at once: it built itself up and came apart over a very long time, with several phases of activity spread between about 400,000 and 93,000 years ago. In the early phases the apparatus raised a large volcanic edifice. Then, as the magma chamber emptied, the summit collapsed, generating the vast caldera that now holds the lake. Scholars call it polycentric because the activity was never concentrated in a single vent but shifted among several eruptive mouths over time, leaving an irregular rim made of several reliefs. The final manifestations built, inside the already formed caldera, the cone of Monte Venere and poured out the Pantanello flow. When, around 90,000 years ago, the fire went out for good, the depression began to fill with the waters of the cold phases of the Quaternary. Anyone looking out from the rim of the caldera sees all of this at a glance: the outer ring of the crater, the young cone in the center, the water occupying the void left by the magma. Few other outings in Lazio let you read the structure of a volcano with such clarity.

A curiosity about Lake Vico (VT)

The curiosity that almost nobody tells concerns the way this lake breathes. A basin closed inside a caldera naturally has no big river to drain it: it would risk rising and flooding the basin. For this reason Lake Vico has a particular outflow, the Rio Vicano, which leaves from the low part of the basin through a tunnel. The artificial stretch that regulates the outflow is about 400 meters long and the concrete structure we see today dates from the 1990s, but the principle of draining the water in a controlled way is very ancient and tied to the agricultural reclamation of the plain below. So the level of the lake you admire in photographs is not entirely natural: it is the result of a balance governed by people for centuries, a detail that explains why the shore is so stable and cultivable almost to the water's edge.

There is also a second record that strikes anyone who knows the geography of Italian lakes. At 507 meters above sea level, Lake Vico is among the highest lakes in the country among those of significant surface area. It is not a small high-mountain lake: it is a true lake of the volcanic plain, yet it sits higher than most of the basins everyone knows. This altitude, together with the closed basin and the woods around it, explains why the air here in summer is cooler than on the shores of nearby lakes and why swimming has a shorter and cooler season than you would expect a few tens of kilometers from the sea.

The legend of Hercules and the club at Lake Vico (VT)

Every strong place has its founding myth, and the one of Lake Vico is among the most beautiful in Lazio. Tradition has it that Hercules, passing through here, wanted to test the strength of the inhabitants. He drove his club into the ground, or according to other versions an iron rod, and challenged the local people to pull it out. Nobody managed. When Hercules himself tore the shaft from the earth, such a quantity of water gushed from the hole that it filled the whole valley and gave rise to the lake. It is a legend, of course, to be read as tradition and not as chronicle. But it has the merit of saying in story form a genuine geological truth, namely that the basin is born from a gash in the ground and from water rising from the depths. Myths, often, are geology told by poets.

Something nobody tells you about Lake Vico (VT)

What the glossy guides tend to skip is that the water of Lake Vico has a chemistry that is the child of the volcano, and this has very concrete consequences. The soils of volcanic origin in the Tuscia naturally release arsenic, and the waters of the area contain it in amounts that, in several recent surveys, have been at or slightly above the limit set for drinking water. For this reason the water intended for human consumption in the nearby territories is treated and purified before reaching the taps. It is not an alarm, it is a characteristic of the volcanic territory, and it explains why the question of water quality has always been followed closely here.

To this is added a second, more seasonal factor: algal blooms. In recent years the lake has seen episodes of cyanobacteria proliferation, also favored by the fertilizers used in the crops around the basin. In some springs and summers high values have been recorded, and swimming has been regulated accordingly. The practical lesson for the visitor is simple: before diving in, it's best to check the updated situation at the beach club, at the Visitor Center or in the surveys of the regional environmental agency, because the state of the water here changes from season to season and must be looked at each time, never taken for granted.

The Lake Vico Regional Nature Reserve

The whole basin is protected. The Lake Vico Regional Nature Reserve was established in 1982 by Regional Law no. 47 of September 28 of that year, and it is one of the reasons the lake has come down to us almost intact, spared the building speculation that devoured the shores of so many other bodies of water near Rome. The protected area, after the 2008 expansion ordered by Regional Law no. 24 of December 24, reaches about 4,109 hectares and includes the entire lake basin. Management, which was originally entrusted to the Municipality of Caprarola, passed in 2008 to the Ente Monti Cimini, the regional body that now looks after the reserve, the trails, the surveillance and the outreach.

The symbol of the protected area is the great crested grebe, the elegant long-necked water bird that nests among the reed beds and that, in spring, stages one of the most spectacular courtships in the animal world. Choosing it as an emblem is not random: it says in a single image that the protagonist here is inhabited water, the living marsh, the forest that comes down to the shore.

The beech forest of Monte Venere and the UNESCO ancient beech forest

On Monte Venere grows a beech forest that botanists call depressed, because it develops at altitudes much lower than those at which the beech usually thrives. The beech is a mountain tree: finding it this low, a few hundred meters above sea level and a step from the water, is a rare phenomenon, made possible by the cool, humid microclimate of the volcanic basin, which reproduces at low altitude the conditions that elsewhere exist only in the high hills. Walking in this beech forest, especially in autumn when the leaves turn copper, is one of the most beautiful experiences of the Tuscia.

A few kilometers away, on nearby Monte Cimino, above Soriano nel Cimino, another, even older beech forest survives, the Faggeta Vetusta del Monte Cimino. In 2017 it became part of the world heritage of humanity, inscribed in the UNESCO serial site of the ancient primeval beech forests of the Carpathians and other regions of Europe, together with other Italian beech forests such as the one at Oriolo Romano. Vetusta means that inside it the forest follows its own natural cycle, with very old trees, fallen trunks left on the ground and a structure that humans have not reshaped: a fragment of forest as the woodlands of Europe must have been before agriculture. If you come to Lake Vico, the Cimino beech forest is the detour worth the trip. You can also get a taste of it in the beech forest of Oriolo Romano, another tile of the same UNESCO mosaic.

The hazelnut groves around Lake Vico (VT)

Anyone driving around the basin immediately notices a crop that dominates the landscape: the hazelnut. The Tuscia of Viterbo, and in particular the area of the Monti Cimini, is one of the Italian capitals of the hazelnut, with orderly groves that climb from the shores toward the hillsides. It is an agriculture of great economic value and ancient tradition, but it is also the point where environmental protection and production meet and sometimes contend for the land: the fertilizers and treatments of the hazelnut groves are among the factors that affect the state of the lake's waters, as the algal bloom episodes of recent years remind us. Observing the hazelnut groves helps you understand that this landscape is not pure, untouched nature, but a delicate balance between protected forest, water and productive countryside, managed day by day.

The flora and fauna of Lake Vico (VT)

The biological richness of Lake Vico is the real reason it deserves a slow visit. The reserve alternates beech forests and cerrete, that is Turkey oak woods, with the reed beds that fringe the shore, the beaches and the cultivated fields. This variety of environments, packed into a few kilometers, hosts a surprising fauna for a lake so close to Rome, and makes it one of the most important wetlands in Lazio for the stopover, wintering and nesting of water birds.

The water birds of Lake Vico (VT)

The protagonist is the great crested grebe, joined by the little grebe. In winter the clearings of shallow water among the reed beds and wet meadows fill with ducks: the common pochard and the tufted duck, diving ducks that dive to look for algae on the bottom, and then the mallard, the wigeon, the gadwall, the teal, the garganey, the shoveler. Coots in great numbers and moorhens are not lacking. Among the herons you can see the grey heron, the great egret, the little egret, the little bittern and the squacco heron. In the reed beds hides the water rail, hard to see and easy to hear.

The great overwintering

For about five months, in the cold season, the lake becomes a dormitory of water for birds: the wintering population exceeds 5,000 individuals overall, among coots and ducks of several species. It is the most impressive natural spectacle of Lake Vico, invisible to those who come only in summer for a swim. Anyone who loves birdwatching finds paradise here in exactly the months when the beaches are empty.

Day and night raptors

The skies above the basin are visited by notable raptors: the lanner falcon, a rare and precious falcon, the common buzzard, the sparrowhawk, the kestrel, the marsh harrier, the peregrine falcon and the black kite. As evening falls the shift changes and the night raptors begin: the barn owl, the tawny owl, the long-eared owl, the little owl and the scops owl, whose monotonous voice accompanies the summer nights.

Woodland and reed bed birds

In the woods you meet woodpeckers, jays, finches, tits, the hoopoe with its unmistakable crest, the tiny wren. The reed bed has its specialists: the great reed warbler, which marks its territory with a loud, grating song in the mating season, together with the little bittern and the squacco heron. In winter, at sunset, thousands of starlings gather among the willows and the reed beds to spend the night, drawing their moving clouds in the sky.

Mammals, amphibians, reptiles and fish

Among the mammals the reserve hosts the fox, the badger, the wild boar, the pine marten, the polecat and the wildcat, ever rarer. The otter, once present, has disappeared in recent times. The amphibians include the green frog, the tree frog, the common toad and the green toad. Among the reptiles you can see the grass snake, the common tortoise and the Aesculapian snake. In the waters swim native species such as the pike and the tench, alongside introduced species such as the whitefish, the European perch and the agone. In spring, anyone with patience and a good pair of binoculars can watch the famous courtship dance of the great crested grebe, which ends with the offer of a tuft of algae as a wedding gift between the two partners.

The advice I give you for visiting Lake Vico (VT)

My advice is to turn the common idea upside down. Most people arrive at Lake Vico on a Sunday in July, look for a spot at a beach club, swim and leave without having seen the best part. The best part is something else: it is the basin seen from above and walked in the woods. Come early in the morning, or better still out of season, in May or October. In May the reed bed is alive with song and the beech wood is a new green. In October the beech leaves turn copper and the low light sets Monte Venere on fire. Take the high road, the S.P. 39, stop at the viewpoints and then go down to walk at least one stretch of a reserve trail.

The verdict is clear: swimming in summer is the most overrated reason to come all the way here, and on top of that it is subject to the whims of the algae. The underrated reason, the one that really repays the trip, is nature in silence during the shoulder months, when the lake goes back to the birds and to those who walk. Bring water, binoculars and real shoes: you don't need high-mountain gear here, but beach flip-flops on woodland trails are a terrible idea.

The trails of the Lake Vico Nature Reserve

The reserve is crossed by a network of marked trails, eight main routes laid out according to hiking standards, which allow you to go around the basin on foot, by bicycle or, on some stretches, on horseback. They range from easy walks along the shore to more demanding climbs toward Monte Venere and the viewpoints on the caldera rim. The updated map of the routes, with travel times and any seasonal closures, is picked up at the Visitor Center: it is the first place to stop, because the state of the trails changes with the rain and with maintenance. For a view from above without too much effort, the stretch of the S.P. 39 with its rest stops remains the most immediate solution.

Swimming at Lake Vico (VT): where and the rules

Lake Vico is swimmable in the equipped stretches, as the checks of the regional environmental protection agency of Lazio have confirmed for years. Swimming is concentrated in the beach clubs and authorized zones along the shore, not everywhere: a large part of the perimeter is protected reed bed and bird habitat, and swimming is not allowed there. In summer the beach clubs offer beach, umbrellas, refreshment points and lifeguard supervision. The golden rule, already stated but worth repeating, is to check the state of the water for the current season: in the years of algal blooms temporary bans were issued precisely to protect the health of swimmers. In normal conditions the water is cool and clean, and the bottom slopes gently, which makes the lake suitable for families too in the supervised spots.

Another well-known fact that is rarely mentioned

The very name of the lake hides a story that almost nobody stops to tell. The origin of the place name is uncertain, and scholars propose more than one track, all Roman. The first calls into play the Vicus Matrini, a Roman settlement of some importance that arose along Via Cassia about three kilometers from the lake, so significant that it appears on the Tabula Peutingeriana, the ancient road map of the empire. The second hypothesis looks to the Vicus Elbii, a small Roman settlement overlooking the southern edge of the basin, which then disappeared by the early Middle Ages. From one of these vici, these villages, the name of the lake would derive.

There is more. The area was crossed by a very ancient artery, Via Ciminia, the inland variant of Via Cassia that crossed the Cimini and passed right through here. In the Middle Ages control of this strategic passage made powerful the family of the Prefetti di Vico, lords who dominated the territory between the 12th and the early 15th century from their fortress built on a height. After them it was the Farnese, in the 16th century, who got their hands on the area. The lake that today seems only a natural paradise was for centuries a hub of power: whoever held the Ciminia held the road to the north.

The right photo to take at Lake Vico (VT)

The photograph you take home and that nobody else has is shot from above, not from the shore. The spot is the Poggio Trincera viewpoint, on the northern rim of the caldera, reachable from the S.P. 39 del Lago di Vico scenic road. From up there the whole basin opens beneath you: in front, the wooded cone of Monte Venere entering the water. To the left and right the rim of the crater. Beyond, on clear days, the gaze even reaches Lake Bracciano and the line of the Tyrrhenian. The best light is that of early morning, when the haze rises from the water and the raking sun draws the reliefs, or the golden light of a late autumn afternoon, with the beech forest ablaze.

The technical advice: a lens that holds together the cone of Monte Venere and the curve of the shore tells the volcanic shape better than a close-up. Avoid the summer midday, when flat light flattens everything and the heat haze erases the horizon. And you don't need a heavy tripod: here the right photo is a matter of time of day and season, much more than of equipment.

What to see around Lake Vico (VT)

Lake Vico is at the center of one of the richest areas of Lazio, and it would be a shame to leave without widening the circuit. A few kilometers away, clinging to the rim of the basin, is the village of Caprarola, dominated by the bulk of Palazzo Farnese, the pentagonal residence built by the Farnese family in the 16th century and one of the absolute masterpieces of Italian Mannerism. Not far away, at Bagnaia, another jewel of the Renaissance is Villa Lante with its Italian gardens and water features.

Toward the Cimini you reach Soriano nel Cimino, with its UNESCO beech forest, and the quiet village of San Martino al Cimino. The city of Viterbo, with its medieval quarter and the Palazzo dei Papi, is a stone's throw away. Further north open the great Lake Bolsena and the spectacular Civita di Bagnoregio, the dying city. For those who love the bizarre, a short distance away is the Monster Park of Bomarzo. Toward Rome, instead, nearby Lake Bracciano closes the circle of the great volcanic lakes of northern Lazio.

Some important events that happened here in history

The recent history of Lake Vico is above all the story of its salvation. In the 1960s and 1970s, as on so many Lazio shores, the threat of building speculation appeared: in the territory of Ronciglione the small residential settlement of Punta del Lago arose, a witness to an urbanization that, if not stopped, could have devoured the banks. The turning point came in 1982, when the Lazio Region established the Nature Reserve with Regional Law no. 47 of September 28. From that moment the shores were withdrawn from concrete, and the lake was able to remain one of the least built-up basins in central Italy.

Since then the recognitions have followed one another like stages of a long protection. In 1995 the lake was identified as a Site of Community Importance. In December 2016 it was declared a Special Protection Area, while Monte Fogliano and Monte Venere had already entered the European network in earlier years. In 2008 management passed from the Municipality of Caprarola to the Ente Monti Cimini and the protected area was expanded to the present 4,109 hectares. On the front of water quality, monitoring has intensified: in July 2018 the sampling by Legambiente's Goletta Verde found no worrying levels of pollution, while in the following years the cyanobacteria blooms have brought attention back to the balance between agriculture and the environment. Every date in this chronology tells the same thing: a lake saved by law and kept alive by vigilance.

Who has passed through Lake Vico (VT)

The mythical figure who opens the list is, of course, Hercules, the hero who according to legend made the lake gush from the earth. Leaving myth and entering history, the first to leave a mark were the Romans, who laid out Via Ciminia here and founded the vici from which the lake's name perhaps derives. In the Middle Ages the scene was dominated by the Prefetti di Vico, the powerful family that from the 12th century controlled the territory and the road, building the fortress on the height of the village of the same name and long resisting the power of Rome.

In the 16th century the Farnese arrived. The family that gave the Church Pope Paul III made nearby Caprarola the heart of its holdings, building the grandiose Palazzo Farnese, and used the woods of the Cimini around the lake as a hunting reserve and leisure territory. Cardinal Alessandro Farnese, a great patron of the arts, tied his name to this corner of the Tuscia more than anyone else. Since then Lake Vico has entered the imagination of Grand Tour travelers and of naturalists who, climbing toward Viterbo along Cassia, stopped to admire the wooded basin and noted its unusual shape, that high lake closed among the mountains. In the 19th and 20th centuries the basin continued to attract geologists and ornithologists, the former drawn by the structure of the extinct volcano, the latter by the extraordinary concentration of water birds. Today anyone passing through here walks, in the end, on the same shores as mythical heroes, medieval prefects, Renaissance cardinals and scholars who in this corner of the Tuscia read the history of the Earth and that of the birds.

Lake Vico (VT) as a day trip from Rome

From Rome Lake Vico is the classic day trip, and it holds its own against more famous destinations. The distance is covered in a little over an hour by car up Cassia, and this leaves time to build a complete itinerary without rushing. The recommended formula is simple: arrive in the morning, a view from above over the basin from the scenic road, a walk of a couple of hours on a reserve trail or along the shore, lunch with the flavors of the Tuscia, and in the afternoon a visit to Palazzo Farnese in Caprarola or the gardens of Villa Lante in Bagnaia. Anyone with a whole day who loves nature can instead devote all the time to the lake, between birdwatching and walks, returning to Rome at sunset. The beauty of this trip is its variety: water, forest, volcano, Renaissance art and country cooking, all gathered in a few kilometers. For those organizing the trip in stages, Lake Vico fits well into a wider tour of the Tuscia that includes Viterbo and its thermal area, or into a loop of the volcanic lakes of northern Lazio.

When to go to Lake Vico (VT)

Every season has its own Lake Vico. Spring, between April and June, is the season of songs and blossoms, with the beech forest a tender green and the birds in full breeding activity. Summer is the swimming season, the most crowded, to be enjoyed in the early hours to avoid the crush and the heat. It is also the period in which it's best to keep an eye on the state of the water. Autumn, from October, is the most beautiful moment of all: the foliage of the beech forest, the low light, the clear air and the almost deserted trails. Winter, finally, is the season of the great wintering of water birds, with thousands present on the lake: cold but extraordinary for those who love silent nature.

Lake Vico (VT) with children

The lake is a happy destination for families, provided you choose the right register. In the supervised spots of the beach clubs the bottom slopes gently and the fresh water, without waves and without salt, is less demanding than the sea for the youngest. Away from the beach, the abundance of birds makes the lake an open-air science classroom: inexpensive binoculars and a notebook for drawing herons are worth more to a child than any toy. The easiest trails along the shore are suitable even for short legs, while the climbs toward Monte Venere remain for older kids. As always, bring water, a hat in summer and check the swimming status before getting in.

The grebe's dance and the mating season at Lake Vico (VT)

If there is one spectacle worth setting an early alarm for in spring, it is the courtship of the great crested grebe. This long-necked water bird with a colorful crest stages, before mating, a real choreography: the two partners face each other on the water, shake their heads in sync, dive and resurface, and conclude the ritual with the mutual offering of a tuft of algae torn from the bottom, a kind of wedding gift. Watching this dance, with binoculars and from afar so as not to disturb, is one of the most intense experiences that Lake Vico gives to those who frequent it. The good season runs roughly from the end of winter to late spring, when the reed beds fill with song again. The great reed warbler marks its territory with a loud, shrill song, the little bittern hides among the reeds, the herons patrol the shores. Anyone who knows the lake only for the summer swim can't imagine how much life bursts out here in the shoulder months, away from the crowd.

Autumn foliage at Lake Vico (VT)

Autumn is the season in which Lake Vico gives its best. From October the beech forest of Monte Venere and the woods on the rim of the caldera turn yellow, orange and copper, and the basin lights up with warm colors reflected in the water. The low light of this season, clear and oblique, draws the reliefs with a definition that in summer the heat haze erases. The trails, crowded in the swimming months, become almost deserted again, and walking in the beech forest under the golden canopy of leaves is an experience that alone repays the trip from Rome. It is also the season of the hazelnuts and mushrooms of the Cimini, which adds the pleasure of the table to the walk. If I had to name a single week to come to Lake Vico, I would pick any one in mid-October, with a clear day and a charged camera: the foliage reflected in the volcanic water is the image this place can give like few others in Lazio.

The climate of the basin and why the water is cool

A detail that surprises those who arrive in summer is the temperature of the water and the air. Lake Vico is at 507 meters of altitude, enclosed in a basin surrounded by woods: two conditions that make it a cooler place than you would expect a few dozen kilometers from the sea. The water warms up more slowly than that of lower lakes, and in the evening, when the air comes down from the wooded slopes, the basin cools quickly. For the swimmer this means a shorter swimming season and water that is always lively, never lukewarm like the sea. For the hiker it means that even on hot days, in the shade of the beech forest, walking is pleasant. It is the microclimate of the caldera, the same one that lets the beech grow here at unusually low altitudes, that makes Lake Vico a place where summer is gentler than elsewhere.

The outlet and the water management of Lake Vico (VT)

It is worth returning, calmly, to the way this lake keeps its level, because it is a chapter of ancient engineering that few people know. A basin closed in a caldera collects rainwater and spring water, but without adequate drainage it would tend to rise and turn the basin into marsh. The solution is the outlet, the Rio Vicano, which collects the excess water and carries it out of the depression through a tunnel. The artificial stretch that now regulates the outflow measures about 400 meters, and the current concrete structure dates to the 1990s. But the idea of letting the water flow out in a controlled way to reclaim the land downstream is much older and has accompanied the agricultural history of this plain for centuries. The level of the lake, then, is not entirely a fact of nature: it is a balance built and maintained, and this explains why the cultivated fields reach almost to the shore in a stable way and why the waterline stays so regular from year to year. Observing the outlet means understanding that in the Tuscia humans and water have been negotiating for millennia.

Ronciglione, Caprarola and the village overlooking Lake Vico (VT)

The basin of Lake Vico is divided among a few municipalities, and knowing them helps with orientation. On the southern side is the territory of Ronciglione, where in the 1960s and 1970s the small residential settlement of Punta del Lago arose: an isolated episode of building on the shores, today a useful reading for understanding what the reserve saved the rest of the perimeter from. Ronciglione, a village of medieval and Renaissance origin, deserves a stop for its old town and for the tradition of its Carnival. On the opposite side Caprarola dominates, the town to which the lake is administratively most tied and on which the management of the protected area long depended: here the bulk of Palazzo Farnese, with its pentagonal plan and its scala regia, tells the power of the family that made the Cimini its private kingdom. The small village of Vico, which gives the lake its name, preserves the memory of the fortress of the Prefetti di Vico. Anyone touring the basin by car crosses in a few hours a condensed version of Lazio history, from the Middle Ages of the feudal lords to the splendor of the Farnese Renaissance.

By bicycle and on horseback around Lake Vico (VT)

The lake is not experienced only on foot. Several stretches of the reserve's routes are open to mountain bikes and, in some segments, to horseback excursions, which lets you tour a good part of the basin at a different pace from walking. The track that follows the shore, where the elevation change is minimal, is the best suited to a family bike ride. The climbs toward Monte Venere and the high points of the caldera rim instead require trained legs and an adequate bike. On horseback, the wooded area offers routes immersed in the beech forest and the Turkey oak woods, with glimpses of the water that on foot you would miss. As always, before setting out it's best to ask the Visitor Center which trails can be used on two wheels or on horseback in the current season, because not all stretches have the same rules and some, in nesting periods, may be subject to limitations to protect the wildlife.

The flavors of the Tuscia around Lake Vico (VT)

A trip to Lake Vico is also a gastronomic opportunity, because the Tuscia of Viterbo has a generous and recognizable country cuisine. The undisputed queen is the hazelnut of the Monti Cimini, the base of sweets, creams and nougats found in all the towns around the basin: tasting their products in the local bakeries and shops is the most honest souvenir of this land. Alongside the hazelnut, the cooking of the area brings to the table the dishes of the Lazio interior, from handmade pasta to legumes, from the mushrooms of the Cimini woods to meats. Many beach clubs on the shore and the trattorias of the nearby villages offer the local cuisine in a simple, hearty version. The professional's advice: if you come in autumn, time the visit to the hazelnut and mushroom season, and leave room in the trunk for a few purchases in the towns of the Cimini.

Accessibility, services and rules of Lake Vico (VT)

Since it is a protected natural area, services are concentrated along the shore and near the lakeside beach clubs, while the forest trails have no refreshment points: anyone setting out must carry water and provisions. The summer beach clubs offer an equipped beach, parking, refreshments and, in the supervised spots, conditions suitable for families with children. Being a reserve, rules of respect for the environment apply: no fires outside authorized areas, no leaving trash, no disturbing the wildlife in the reed beds, no picking protected plants. Dogs must be kept on a leash, especially in the nesting areas of water birds. For precise information on trail accessibility, swimming conditions, guided visits and any seasonal closures, the reference remains the Visitor Center of the managing body, which updates the information as the seasons pass.

Lake Vico (VT) and the other volcanic lakes of Lazio

To truly understand Lake Vico it's best to place it in the family it belongs to. Northern Lazio is a land of great volcanic lakes, all born from the same ancient fire but with different characters. Nearby Lake Bracciano is wider and lower, famous for its shores and its villages. Lake Bolsena, further north, is the largest volcanic lake in Europe, with its two islands. Compared with these elder siblings, Lake Vico plays the card of intimacy and altitude: smaller, higher, more enclosed, less built up, protected in its entirety by a reserve. It is the wildest of the three, the one in which nature still has the first word, and for that reason the most loved by those looking for silence and birds instead of beach life. An itinerary that links them all, from Bracciano to Vico to Bolsena, is one of the most beautiful volcanic routes that Lazio can offer.

Lake Vico is one of those places that reward those who slow down. If I had to give a single suggestion, I would say not to treat it as a spare beach for hot Sundays, but as a small world enclosed inside a volcano, where the water, the forest and the birds tell a story that has lasted 90,000 years. Come off season, climb to the rim of the caldera in the morning, walk a stretch of beech forest and leave the camera on: that is how this lake makes itself remembered.
