Excellent experience; highly recommend it! We went with “Fins & Feet Nature Tours” just my friend and I, with Rob as our guide. We liked the idea of not having to deal with a boat, with risk of getting seasick, and also boats aren’t as eco- friendly for the fish & reef. Rob picked us up at our hotel in a van, had a selection of good masks & fins in different sizes, and drove us right to 2 great snorkel spots; first one for sea turtles; saw lots of them, & second site for great reef with lots of fish. He brought a small buoy/ round flotation device that he held and we could hold onto it when tired or for security if less experienced. We’d done snorkeling years ago but were out of shape and had basically forgotten how, & Rob was really patient and a great instructor, and told us all about the island as well. They can be very flexible as these are private snorkel trips; just whoever you sign up with. Definitely give them a try!
