On St. Croix we took the Buck Island Snorkel Excursion. If you are looking for a shopping tour, Frederiksted doesn’t have a lot to offer and Christiansted doesn’t have much more. We took a taxi to Christiansted to get to the pier were we depart to Buck Island. The boat never touches the beach and you snorkel directly from the boat. You are in ten feet of crystal clear water. This was my first time snorkeling and I enjoyed the corals but I would of liked to see more fish. We snorkeled for an hour and then returned back to the ship.
