Under the Sea in San Juan. - Fun time walking underwater, feeding the fish and our guide held a blowfish in his hands. Water was beautiful and the guides were fun. Very easy breathing with the helmet.

Amazing birthday - I did this today for my birthday and I must say it was the best experience ever. I had such an amazing time and experience. I don’t even know how to swim and I had a ball. I was very relaxed and you will feel very comfortable and at ease. Definitely is a must try when visiting Puerto Rico,

Cool Experience! - This was such a fun and cool experience. Our kids are 14 and 11 and had a blast. The weight of the helmet is about 75 pounds but it is only 12 to 15 pounds in the water so small kids could definitely do this excursion because the helmet sits on the shoulders and they have pads for it. Our guides were excellent. I would recommend wearing water shoes.

So much fun! - Alejandro Guzman led us on an underwater scuba experience that was truly unforgettable. He was patient, kind, and extremely knowledgeable, which made us feel comfortable and confident the entire time. He and his team guided us underwater to explore a reef, where we were able to see incredible marine life, hold a crab, and even feed fish. It was such a unique and special experience. Alejandro also took many photos throughout the dive and made sure we received them afterward, which was so thoughtful and meaningful for our photo album. I would absolutely recommend this activity and Alejandro to anyone looking for a memorable underwater experience.
