Notes:
Big Bog State Recreation Area has been called Minnesota's last true wilderness. This two-part recreation area includes a northern unit and a southern unit. The 500-square-mile peat bog, the largest in the lower 48 states, is located in the northern unit. A mile-long boardwalk, completed in 2005, enables visitors to get a first-hand look at the unique plant and animal life of this rare resource. The bog, which has long been a source of medicinal plants for the Ojibwe Indians, represented a barrier to European settlers who tried in vain to drain it. Today, many of the native plants, including yellow-eyed grass, bog rush and two kinds of sundews, are on Minnesota's endangered or threatened species list. From orchids to carnivorous plants to rare birds, visitors will see a mixture of fascinating and rare resources. The southern unit includes a campground with 31 campsites (26 electric sites) winterized camper cabins, a sandy beach, picnic grounds, and great fishing.
