During the summer, crowded backcountry trails can be as frustrating as the Santa Monica Freeway. Not so on Lake Superior's Isle Royale, which sees fewer visitors in a year than many parks get in a day. Don't be fooled by the lack of attention. A designated "International Biosphere Reserve," it's arguably the most primitive wilderness camping and kayaking experience in the Midwest, with no roads and 165 miles of hiking trails, many of which shadow ruggedly beautiful shores haunted by shipwrecks. The island is home to moose, river otters, and more than 25 different species of wild orchid, some rarely seen anywhere outside the park. The island is most famous for its gray wolves that roam in several packs, but you'll be lucky to even see them. [nps.gov/isro]
