Secret Harbour is a relatively small beach with great amenities anda great voew all around. You can snorkel, use the water platform, or lounge about. The restaurant on the beach (Sunset Grille) is pretty good - go for the ahi tuna nachos. The Aqua Action Dive Shop rents out snorkel gear, chairs and more. This beach does not get as crowded as some of the extremely well known St Thomas beaches. Just a beautiful spot.
