About the Island

Three Mile Island Camp is an AMC full-service camp located three miles down the lake from the northern end of Lake Winnipesaukee in New Hampshire. Built on a 43-acre island in 1900, campers enjoy a relaxed and simple life that has changed little since the camp's founding. It is a place where several generations of families and newcomers alike come to swim, fish, kayak, canoe, and sail in New Hampshire's largest lake. Many enjoy hiking in the nearby White, Ossippee, and Bald Peak mountain ranges. And all relax with friends and family, with three delicious meals provided (special dietary needs are accommodated) for stays of either one or two weeks in the summer and four weekends in the fall.

Three Mile Island Camp is a volunteer-managed, family-oriented facility of the Appalachian Mountain Club. Located on Lake Winnipesaukee in Meredith, NH, "Three Mile Island" welcomes AMC members and the general public to summer and fall camping opportunities.

Situated on an island of 43 rocky woodland acres, this shorefront camp offers families a delightful recreational experience in the heart of New Hampshire's lake district. Exploration of the woods, swimming, boating, and conservation programs are just a sampling of the pleasures this island getaway offers.
