Must-see excellent snorkelling tours - Super friendly staff! Thanks so much to Alex, our dive instructor. Exploring the archeological sites under water is something I have never experienced anywhere else. And most of the mosaic are in such good condition that you wouldn’t think they are about 2000 years old.

Very good snorkelling experience - We took a family snorkelling dive in early March. The visibility was very good. It's very impressive to see these ruins submerged. Andréa and Alessandro the two young owners of the center are pure hearts united by their love of the sea, we wish them the best. The suits are quality and in good condition. The English explanations were clear and Fransesco watches over the boat during the outings. We feel safe.

Snorkeling Over Ancient Ruins - Fabulous dip into the Mediterranean. Alessandro "led" us over the ruins of Baia, making sure we knew what we were looking at, and giving each person time to dive down to see for themselves. Wet suits, flippers, masks and snorkel were provided. Bring your own towel!!! We had a non-swimmer in our group and even she was coaxed into the water, as the wet suits are buoyant. It was an experience to remember for a lifetime.

Interesting experience - There were beautiful mosaics to see. The staff were very friendly and helpful. Unfortunately, the place is difficult to reach by public bus from Naples because the buses do not run reliably, but the snorkel group was kindly waiting for me.

Great sites, great knowledge - A very fair fee for an hour in the park. Alessandro was friendly and knowledgeable. We got very lucky with the weather and the mosaics were easily visible from the surface! We ended up in a group of only three so got to see everything and spend time properly looking. Thank you!
