In a nutshell

A one-of-a-kind experience: with mask and snorkel, you’ll explore the remains of an ancient Roman city, sunken beneath the sea due to a natural phenomenon. Glide over mosaics, baths, villas and perfectly preserved statues in what is considered the Italian Atlantis. A journey through time... underwater!

The programme

In the sunken Park of Baia experience an adventure in the kingdom of the volcano. From the constantly active Phlegraean Fields area you’ll set off for the ancient Roman city, which you’ll discover one stroke at a time.
Before diving in, your instructors will get you ready with masks, fins and snorkel. Snorkeling is simple even if you have little experience, and you’re guaranteed to have fun.
With one fin stroke after another, you’ll move across the blue waters of the archaeological park. From the water’s surface, you’ll see all its inhabitants: fishes, algae and other marine life.
A little further on, you’ll make out the Via Herculanea, once the city’s main road. And, exploring from above, you’ll recognize workshops, ruins of villas, banqueting halls and even two thermal bath areas.
It seems incredible, but this sunken world was once on land. Baia was plunged into the sea by bradyseism, a natural phenomenon of volcanic origin which raises and lowers the level of the ground over the course of centuries.
And so, while you swim over silent statues and remains of mosaics, you see the city’s history re-emerge, and you’ll take this with you on dry land too.

Good to know

Only bring what you need: a swimming costume, a backpack with beach towel, a hat, suncream and bottle of water.
We'll provide the fins, mask, and snorkel.
