Totally free of vehicles and roads, Isle Royale National Park, a 210-sq-mile island in Lake Superior, is certainly the place to go for peace and quiet. It gets fewer visitors in a year than Yellowstone National Park gets in a day, which means the 1600 moose creeping through the forest are all yours.
The island is laced with 165 miles of hiking trails that connect dozens of campgrounds along Superior and inland lakes. You must be totally prepared for this wilderness adventure, with a tent, camping stove, sleeping bags, food and water filter. The park is open from mid-April through October, then it closes due to extreme weather.
