    The man who helped us and we ended up snorkeling because was so patient and helpful I actually succeeded at learning how. The staff was both kind and helpful and I am nearly 80 years old but was still able to have the adventure of a lifetime. Noted-the water was warm and clear, and if someone has never tried seeing the ocean close up, this is an amazing way to do that. Highly recommended.

  • If you like snorkeling, you will love this experience

    Really enjoyed a new experience and had the chance to see all the fish on the bottom of the sea bed, even though we were not that far out. It was a different experience to snorkeling

    This was an incredible experience! No swimming required. You'll be walking the whole time as you gain depth. Perfect for beginners looking to get into underwater activities!

    This was a cool experience. It is in a small bay off of the hotel property and even with hotel guest swimming in the area, there is a decent amount of fish to see; particularly as you get out deeper. The team takes photos and video of the excursion that you can review and purchase separately, if interested. They do a good job and you get a decent amount of photos and a few videos. This may be affected by group size as we did it with just two other people. Afterwards, you get a wristband that allows you to stay on the hotel property to use features such as their beach or pools.

  • Best helmet dive ever

    Dale T,Apr 30, 2026

    - Review from Viator

    We did a similar helmet dive in St Thomas, but this one is 10 times better. The one in St Thomas uses airlines connected to the shore and a restricted underwater path that limits where you can go. The one in Puerto Rico uses air from tanks that float above you, giving each person much more freedom of where to travel. That being said, the guide traveled along with us each step of the way to ensure our safety. The highlight was when the guide put out some fish food right in from of our face mask and the fish swarmed all in front of us. A photographer took lots of photos for those interested in purchasing images of the excursion. After getting out of the water, we were given access to the exclusive resort guest pool, which added to the value of this excursion. Highly recommended.
