Whitefish Dunes State Park sits on the quieter side of Door County with beguiling mounds of sand that warm up on hot days while waves from Lake Michigan cool you off. Get enough wind, and you can body surf the Great Lake. Before you get too gritty at the beach, explore the nature center’s displays on the dune eco-system and a movie about the people who have lived at the dunes as far back as 3,000 years ago. There are replicated wigwams in the woods, along with frequent naturalist programs. Take time, too, to hike along cliffs at the adjacent Cave Point County Park.
