Recreation on St. John [1] generally has one aim: to bring you closer to the exquisite natural beauty of the island. Hiking and snorkeling are the most popular pursuits because they are rewarding, easy, and require little gear. For people seeking something a little more involved, there are also opportunities for biking, kayaking, scuba diving, windsurfing, and sailing.
For some of the most rewarding activities, check with the Friends of Virgin Islands National Park (340/779-4940, www.friendsvinp.org [2]), which organizes guided hikes, workshops, arts and crafts lessons, and other fun educational activities. Past workshops have showcased traditional island cooking, how to take better nature photographs, and stargazing. The organization accepts donations in support of its conservation work.
