Double Dive in the Bay Park for certified divers

Sweetest divers and fun experience swimming around in the sunken city!!

Nice experience and sweet people! In the briefing we were told about the places we went too and then when diving they showed everything, even simulating the hot floors which was so cute! We also stayed to eat with the divers as there were left overs and got to know them a bit better which was a lot of fun:)! The diving was different than I am used too, because it’s really like going to an underwater museum in a way, looking around at the mosaics and different rooms of the Vila’s or harbour etc, instead of swimming a guided tour along a wall for example. And the fish there swim with you lol! There was actually a lot of life and I even spotted a tiny tiny eel/Murray (as big as my pinky finger). Anyhow, great vibe and would recommend <3!

Diving at the Baia Submerged Park for certified divers

amazing experiece

I booked a dive in the morning. The weather was a bit cool at 15 degrees Celsius, but sunny. It was a fantastic experience to see the various mosaics and remains of the Villa a Protiro. The sight was ok but it of course depends on the weather. The dive was about 45 minutes in shallow whater of about 4 to 5 meters. The SeaWorld team is very professional and the atmosphere was great. I would definitely do a dive there again.
