The largest freshwater system in the world by area, the Great Lakes border eight American states and one Canadian province. Like inland seas, Lakes Erie, Huron, Michigan, Ontario and Superior are subject to wind-whipped waves and strong currents and are so big that rarely can you see across them.
In summer, beach lovers flock to their shores at parks such as Sleeping Bear Dunes National Lakeshore in Michigan, and along more obscure strands.
Swimming in the lakes is usually bracing, best appreciated during the dog days of summer. While these freshwater shores come rocky, cliff-walled, dune-lined and wetland-filled, the following six destinations offer some of the best sandy stretches for families. (Hotel rates reflect August stays.)
Lake Superior
Bayfield Peninsula and Apostle Islands, Wis.
The Bayfield Peninsula, roughly 70 miles east of Duluth, offers some of the most inviting beaches on Lake Superior, the deepest, coldest and most forbidding of the Great Lakes. Most travelers come to kayak and island-hop among the Apostle Islands National Lakeshore, a chain of 21 isles and 12 miles of mainland shore.
Summer visitors may be tempted to dip a toe in Superior, starting at Bayview Beach just south of the town of Bayfield. A one-mile walk along the beach with inviting shallows reaches Friendly Valley Beach. Seven miles north of Bayfield, the Red Cliff Band of Lake Superior Chippewa manages the first Native American national park, Frog Bay Tribal National Park, featuring a quarter-mile hike to the sandy shore with views of five Apostles.
Twenty-five-minute ferry rides from Bayfield reach the most accessible of the Apostles, Madeline Island (cars from $38 round-trip). There, Big Bay State Park and nearby Big Bay Town Park offer access to a 1.5-mile sand spit and Big Bay Lagoon.
Where to stay: Woodside Cottages of Bayfield offers cozy cabins paneled in knotty pine with fireplaces and kitchens (from $175).
