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

People have been fighting over Lake Champlain as long as there have been personal flotation devices. The waterway’s strategic value is evidenced by the dozens of shipwrecks on the bottom. The Lake Champlain Maritime Museum has been discovering, researching and protecting those rusty relics, and the result is the Lake Champlain Underwater Historic Preserve, a gallery of sunken ships accessible to divers. But there’s plenty to look at on land, too. The dry museum chronicles the maritime history of the area through exhibits, boat-building demonstrations, lectures and festivals.
