What Travellers Say
Reviews Summary
Baiae Archaeological Park is a unique and fascinating site, offering a rare glimpse into a submerged Roman city. Visitors are captivated by the underwater ruins, especially when visibility is good. While the historical significance is undeniable, some reviewers note that dive gear maintenance can be an issue, and the marine life is not the main attraction. The glass-bottom boat tour is a popular alternative for those not diving.
"It was a unique and interesting experience. We got to see the archaeological underwater park and swim among fish. A perfect mix of history and adventure 👍☺️ highly recommended!"
Olga Nikolajenko
"Great experience however low visibility on the day we went Aug 10th. You do see ruins. The Roman floors are the best thing to see. This dive shop is difficult to locate as it is at a resort on the beach side of the railroad so you have to walk through the pedestrian tunnel to get there. Park in the parking lot for the beach goers North of it and walk back."

🎫 🏛️ History & Significance
Baiae was a luxurious resort town for wealthy Romans, known for its thermal baths and opulent villas. It was submerged due to seismic activity and volcanic phenomena.
Baiae was submerged over centuries due to bradyseism, a geological phenomenon causing the land to rise and fall.
You can see the remains of villas, thermal baths, nymphaea (water features), and even parts of the ancient city's infrastructure, both above and below the water.
