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."

"Good experiance, did not see a lot. But glad we did it. Very nice people"
