Comprising 34 islands, the Boston Harbor Islands National Park Area is somewhat of a hidden gem for nature lovers and history buffs, with miles of lightly traveled trails and shoreline and several little-visited historic sites to explore. The focal point of the national park is 39-acre Georges Island, where you'll find the partially restored pre-Civil War Fort Warren that once held Confederate prisoners. Other islands worth visiting include Peddocks Island, which holds the remains of Fort Andrews, and Lovells Island, a popular destination for campers. Lovells, Peddocks, Grape, and Bumpkin islands allow camping with a permit from late June through Labor Day. There are swimming areas at the four camping-friendly islands as well, but only Lovells has lifeguards. Pets and alcohol are not allowed on the Harbor Islands. The National Park Service (617/223-8666. www.bostonislands.com) is a good source for information about camping, transportation, and the like.
