No passport needed for U.S. citizens and easy flights into St. Thomas. This charter destination is becoming more popular the last several years. Saint Thomas, Saint John, Water Island, St. Croix, and the many surrounding smaller islets and cays all have something unique to offer. There are seven national parks, beautiful beaches, great hikes, delicious onshore restaurants and fun beach bars. You also won’t want to miss a visit to Limeout (limeoutvi.com), the floating taco restaurant only accessible by boat.
