If one water sport is king on St. John it’s snorkeling. Most beginners go to the underwater trail at Trunk Bay, which is hundreds of miles long. The National Park Center, as well as Caneel Bay, also offer round-island tours, which last the better part of an entire day, but will take one to three or four location that aren’t reachable by foot. Another favored spot is Flanagan's Cay off the Southeastern coast and features impressive 12-foot coral heads.
