Most of St. John is a National Park. The beaches are the real highlight: a slow cruise past Caneel Bay, through Durloe Cays, leads you to the picture postcard Trunk Bay, with it's underwater snorkel trail. Similar sights await at beautiful Hawknest Bay and Cinnamon Bay. The sea turtles make the waters around St. John their home, so keep a sharp eye out, and if you see any swimming around your boat, throw them some lettuce! If you enjoy hiking, then check out Reef Bay Trail and view the pretoglyphs at the end of the trail.
If you enjoy history, stop by the Annaberg Plantation for a tour of the old sugar mill ruins. You clear back into U.S waters at Cruz Bay, a small artistic community on the western end of St. John. Mongoose Junction, easy walking distance from town, is an interesting stop. There is a very nice shopping mall with gift shops, jewelry stores and craft vendors.
