An Unrivaled Underwater Nature Trail
The snorkeling is legendary at this uninhabited satellite island off St. Croix, where an elkhom coral reef lies in crystal-clear waters (think 100-foot visibility) at an average depth of 13 feet. Off Buck’s northeast end, a meandering snorkeler’s trail is marked with explanatory plaques so you’ll surface knowing the difference between one forest of sculpture-shaped coral and another. The reef abounds with more than 250 species of fish, including queen angelfish, parrotfish, iridescent blue tangs, sergeant majors, and a host of other colorful creatures who remain remarkably nonplussed in your presence. Much of the reef is protected as an underwater national park.
