Gaeta Beaches: Sant’Agostino, Arenauta, Serapo

The Gaeta beaches covered in this guide are two, and both lie along Via Flacca (state road SS 213): the Sant’Agostino bay, about two kilometers long, and Arenauta, reached by the Trecento Gradini staircase. At both, access to the free beach costs nothing. The services differ: Sant’Agostino has lidos and kiosks, while the free stretch at Arenauta has no ticket booth, no opening hours and no lifeguard.

This text is based on the listings published by estateromana.com. Where a practical detail is missing, we say so and point you to the listing for that place or to the official website. For the full list of coastlines, see our beaches near Rome page.

Gaeta Beaches at a Glance

The table sums up the data in the listings. For everything else, lido prices included, it is best to ask for confirmation on the spot.

Sant’Agostino Beach: The Bay on Via Flacca

Sant’Agostino beach fills the bay of the same name on the western side of Gaeta, in the province of Latina (postal code 04024). It sits along Via Flacca, roughly between km 20 and km 21, just before the tunnels that lead toward Sperlonga. Of all the Gaeta beaches, it is the first one you meet when arriving from that side.

The sand runs for about two kilometers and alternates free stretches with lidos, kiosks and holiday villages. If you just want to lay down a towel, use the free beach: you don’t pay and you don’t book. There is no ticket booth and no closing time.

Umbrella, Sunbeds and Prices

You rent an umbrella and sunbeds at the lidos. Price lists are posted, and each operator sets its own. The listing gives no figures, so we don’t either: ask for the price before you settle in.

How to Get to Sant’Agostino

By car, you arrive on Via Flacca, the only road that serves the bay. Parking is private, and nearly all the roadside dirt lots charge a fee in the warm months. By train, you get off at Formia-Gaeta station. For the onward connection to the bay, schedules and runs included, the listing refers you to official information: check it before you leave.

Arenauta and Trecento Gradini: The Way Down from Via Flacca

On maps and signs, Trecento Gradini beach almost always appears as Arenauta beach. It opens along Via Flacca, on the stretch of coast between Sperlonga and Gaeta. Among the Gaeta beaches, it is the most secluded: the listings classify it as a cove and hidden beach, as well as a free beach.

The main entrances are between km 23 and km 24, on the sea side. The best known is the staircase marked Trecento Gradini, the last way down you come to when heading toward Gaeta and Formia. The listing does not give the exact number of steps or the time needed to descend.

What You Won’t Find at Arenauta

There is no public ticket booth. There are no opening hours. There is no lifeguard on the free beach. Anyone choosing this stretch should bring what they need and judge the sea conditions for themselves. The listing gives no list of services for the individual establishments facing the road: ask the operators directly.

How to Get to Arenauta

You get there by car or motorbike. Parking is private and paid, and nearly all of it belongs to the establishments and hotels along the road. You can also arrive by sea in a small boat. Public transport serves Via Flacca with suburban runs; the listing is not enough to give you lines and times, so check them on the transport operators’ websites.

Gaeta, the Town: Getting There and Where to Park

A day trip to the Gaeta beaches usually starts in Rome. The listing for Gaeta gives about two hours by car. The fastest route takes the A1 motorway to the Cassino exit and then the expressway toward Formia. The alternative is Via Pontina and then Via Flacca along the coast: it is slower, but passes through Terracina and Sperlonga.

By train, you get off at Formia-Gaeta station, on the Rome-Naples line via Formia. From Roma Termini there are regional and Intercity trains, with travel times from an hour and ten minutes to an hour and a half depending on the train. From there you take the Cotral bus to Gaeta.

Cotral Bus from Formia

Runs are frequent on weekdays and much sparser on Sundays. The terminus is at Piazzale Caboto, below the walls of the medieval quarter, with stops along Corso Italia and on the seafront. The Formia-Gaeta ticket costs a little over a euro and the ride takes about half an hour. If you are going for the day, check the Sunday timetable before you set your return time.

Parking in Town

Drivers will find paid blue-line spaces along the whole of Lungomare Caboto and at Piazzale 5 Febbraio, at the foot of the old town. The listing names other parking areas: read it in full before you leave. The medieval quarter, with its churches, is easy to visit on foot and pairs well with a morning at the beach.

How to Choose Among the Gaeta Beaches

The choice depends mostly on which services you need. A few criteria, drawn from the listings:

• Services and rentals: Sant’Agostino has lidos and kiosks, with umbrella and sunbeds for rent. Each operator sets its own price list.
• Free beach without services: at Arenauta the free beach has no lifeguard and no ticket booth.
• Train: the reference station for both areas is Formia-Gaeta. The final leg should be checked with the transport operators.
• Car: Via Flacca is the only road that serves the Sant’Agostino bay. All the parking mentioned in the listings is private and almost always paid.
• Day trip: both listings are tagged as day trips and as outdoor places suited to summer.

The listings do not state the number of parking spaces, the depth of the water, or whether there are facilities for children and people with disabilities. If those matter to you, ask the lido operators or check the official channels.

Practical Tips Before You Go

Keep in mind that Via Flacca is the only way into the Sant’Agostino bay and that parking is mostly paid in the warm months. Bring cash for parking and ask the price before you leave your car. For umbrella and sunbed rental, compare the lidos’ posted price lists.

At Arenauta, where there is no lifeguard on the free beach, choose the time of day and the sea conditions carefully.

Beware of Other Places Named Sant’Agostino

The name Sant’Agostino appears in other places in our catalog and should not be confused with the Gaeta bay. Bagni di Sant’Agostino is the southernmost stretch of coast in the municipality of Tarquinia, in the province of Viterbo, and has nothing to do with the Gaeta beaches. The Basilica of Sant’Agostino in Campo Marzio is a church in Rome, near Piazza Navona. If you are looking for the sea at Gaeta, always check that the listing mentions Via Flacca.
