Button Bay is one of the best beaches on Lake Champlain: The water’s clean, and you can rent canoes and kayaks right there. If neither swimming nor boating appeals, there’s always the area’s unique geology: flat round “button-like” rocks along the shoreline are great for skipping. Seventy-three campsites and 13 lean-tos beckon if you feel like staying over. Samuel de Champlain, Ethan Allen, Benedict Arnold and Ben Franklin all did. PHOTO: CAROL DINGLEY
