The experience was great. The staff members were very friendly and very attentive. The actual “sea walking” was a about 25 min and we did not get to see a lot of fish but the guide tried their best. To be fair it could have been the weather and not the tour.

A unique experience I had never worn a brief and I had never walked underwater, 5 meters (no ears problem at this small depth) But what a spectacle... fish of all colors, coral, sea anemones... just a dream And what about the boat team Incredible, kind and considerate people One of my best life experiences

This was such an incredible experience! There were three of us and my kids were 11 and 15. The boat can take a maximum of 4 people at a time. There were three crew members and they take such good care of the three of us. I have done a lot of these types of guided dives and snorkeling activities, and this experience provided the best diving suits and shoes. Everything is practically new. So many fish surrounded us right away and the experience of walking under water was totally surreal. When our friends and family saw our photos and videos, they thought the fish were added in via AI…. Haha They took a lot of pictures and videos for you then immediately airdrop them to you at the end of the trip. The lead guide Yuyichi speaks perfect English. The price is incredibly affordable for the out of world experience. Totally recommend!!
