5.00This was such an incredible tour and the highlight of our trip! Our guides were Zack and Leo, who were super friendly, knowledgeable and did such an amazing job with the group! Zack explained everything perfectly, so we knew exactly what was going on/what to expect. They made sure to actively check on the group to make sure everyone was safe and comfortable (including me when I had a brief moment of anxiety in the beginning). I absolutely loved the photos/videos they took while in the water. Definitely worth purchasing!! As for the actual experience – AMAZING!! You don’t need to be a swimmer to enjoy this incredible activity. Seeing the fish (getting to feed them), playing “volleyball”, etc… – all of it was perfect. I really can’t recommend this activity enough!! If you are in San Juan – PLEASE DO IT!!

5.00An absolutely incredible experience! It was surreal being able to breathe normally while walking on the ocean floor. We saw so many colorful fish and the guides made us feel completely safe the whole time. If you aren’t a strong swimmer but want to see the reef up close, this is a must-do!"
Just book it!!

5.00It was an amazing experience considering I’m a non swimmer. Our tour guides were very tentative and informative of what to expect once you’re in the water. I would definitely recommend and rebook again

5.00We did this last year and had to come back for another go. It was even better than last time - water shoes instead of crocs, the briefing is on the beach and in the shade (last time we did it in the water and I got a bit of a sunburn), and they took some great footage, both video and stills. It’s easy to equalize from the pressure because you can reach up inside the helmet if you need to pinch your nose. Lots of fish all around you. We got messages warning about tough parking so took an uber, but it was midweek so there was tons available even in the parking lot where you meet. Thoroughly recommend.
Great vibes great people...
