On Michigan's Upper Peninsula, Porcupine Mountains Wilderness State Park is gorgeous, with 90 miles of trails through old-growth forest, 25 miles of Lake Superior shoreline and four inland lakes.
Hiking is best in late summer and fall, when bugs are gone and hardwoods turn colors that are among the region's most vivid.
What to do: Hike the Escarpment Trail above Lake of the Clouds (pictured). See waterfalls along the Little Carp and Presque Isle rivers. Take a workshop at the Porcupine Mountains Folk School.
Events to catch: Aug. 23-25, Porcupine Mountains Music Festival.
Where to stay: The park rents 19 rustic cabins, four yurts and a handsome 1940s lodge.
