Description

Have you ever seen a city underwater? Explore the wonders of the ancient Roman city of Baia, the Roman city where luxury was the standard, which today is partly submerged due to the strong volcanic activity of the Phlegraean Fields, the geological area where we find ourselves. The phenomenon called bradyseism has slowly brought the level of the earth down over the years, so today the Roman villas that stood in front of the sea are about four meters underwater and the sea has preserved them wonderfully. Come with us to see the ancient Roman city of Baia, you can experience the thrill of swimming on an ancient city today inhabited by so much marine life. All the remains, being no more than four meters deep, have perfect visibility from the surface and you can easily admire them while snorkeling!

My Favorite Tour of My Trip!

This was my family's favorite activity of our entire trip! The first hour of the tour is used for equipment fitting, safety briefings, and sightseeing overview (with a bit of history about the ruins!). The next hour is on the boat and in the water where you see a portion of the Baia ruins. The last half hour is used to shower and change into dry clothes! The employees of the diving center were kind and knowledgeable. I felt very safe the entire time. Be sure to bring a waterproof phone lanyard, a dry towel, and a change of clothes!

Awesome

Amazing experience. There is a train/ subway from Naples. Then just a short walk to the shop. We'll worth the trip.

Great day out, must do

​An Absolute Blast on the Water, highly Recommend! ​We had such a brilliant day out! The entire experience was fantastic and worth every single penny. ​The staff are exceptionally knowledgeable, friendly, and just great fun to be around. A massive shout-out to Mickey (I'm pretty sure that was her name!), who was absolutely fantastic and kept everyone in great spirits. ​It's an incredible day out and an absolute must do, just make sure you don't fall out of the boat! We would highly recommend this to anyone looking for a fun adventure.

Just book it!

What an extraordinary experience! Never done anything like it and was quite nervous to begin with. The team and especially Elioth were all extremely calm and kind, he explained every step of the way and he made me feel very at ease. He’s very gentle, funny and speaks very good English. It was a beautiful day, sea was warm and visibility was good. It took me a while to get used to ‘breathing underwater’ but when I did and saw the ruins up close it was magical. As a solo young woman and someone who can struggle in social situations like these, I really did feel safe and very happy with the whole experience - so if you’re thinking about booking it, just do it! A big thank you to the team and Elioth, I wish you the best😄🧡

Amazing staff and a great experience

I took my mother and brother on one of the snorkeling excursions and we all had an amazing time. It was run so smoothly and every staff member was incredibly friendly and nice. They even messaged earlier in the morning to inform us that the train was cancelled and instructed us on how to get to them via bus or taxi. Tessa, our guide, was super knowledgeable and a great help in and out of the water! We got to spend about 45 minutes exploring the one site and it was truly fantastic. Would definitely recommend and my family already wants to go again!

A magical must do!

A fantastic and magical experience. Extremely friendly and helpful guides who gave a lovely background briefing of what we would see, a pace that allowed for full appreciation and an overall pleasure. One of the coolest things I've ever done while travelling. The fighters mosaic is stunning! As a beginner to snorkeling, I was quickly at ease and learned a few skills, thanks to my guide Andrea. And the office staff were also extremely accommodating, amiable and prompt in their replies. I would urge anyone who goes to Naples to take the train to Baia and experience the archaeological park with Sea Baia.

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.
