This is a national monument and can only be visited by boat. Please respect it and its beauty when here. We took a tour that let us snorkel an hour and say a school of blue tang (at least 200) lots of other fish and coral. I felt like I was swimming in a giant aquarium. Coral is mostly dead, but with concerted efforts it has begun to grow again. That was wonderful to see as we have snorkelled the Great Barrier Reef and hope that st croix could become that pretty a landmark of live beauty. Afterwards we went to the island, no landing the boat so we had to swim ashore. Softest sand I have ever felt. Don't miss this one.
