Ostia Antica Day Trip: Ancient Roman Port & Coast by Train from Rome

Ostia Antica at Sunset

Just 30 minutes from central Rome, Ostia Antica is one of Italy’s best-kept secrets. Once the bustling seaport of ancient Rome, it’s now a sprawling archaeological park filled with temples, houses, warehouses, and intricate mosaics. In September, the cooler weather and smaller crowds make it an ideal day trip—easy to combine with a walk on the beach or a seafood lunch along the coast.

What to Expect

• An easy train journey from Rome’s Piramide station to the site entrance

• A vast Roman city you can explore at your own pace, with minimal crowds

• The option to continue to the seaside for a relaxed afternoon

• A mix of history, nature, and local food all in one day

Five Things to Do

1. Walk the Decumanus Maximus – The main street of Ostia Antica, lined with shops, temples, and the remains of apartment buildings.

2. See the Baths of Neptune – Famous for their preserved mosaics depicting the god of the sea.

3. Climb the Roman Theatre – Still used for performances today, with excellent views over the ruins.

4. Explore the Forum and Capitolium – The political and religious heart of the city.

5. Visit the Borgo di Ostia Antica – A small medieval hamlet near the entrance, perfect for a quick coffee before heading to the coast.

Coastal Add-On After exploring the ruins, take the local train to Ostia Lido for a stroll along the promenade or a plate of fresh seafood at a beachfront trattoria. If you prefer a quieter option, head to Fiumicino for fishing boats, narrow streets, and waterfront dining.

Where to Eat

• Ristorante Monumento dal 1884 – Traditional Roman cuisine in the old village.

• La Bussola (Ostia Lido) – Fresh seafood with sea views.

• Osteria dell’Orologio (Fiumicino) – A more upscale option with creative seafood dishes.

Travel Tips

• From Rome, take the Roma-Lido train from Porta San Paolo (connected to Piramide Metro B).

• Wear comfortable shoes—the archaeological park is large and mostly unshaded.

• Arrive early to enjoy the ruins before midday.

• Combine history and seaside relaxation for a perfect September day trip.
