It has been called Minnesota’s last true wilderness. Divided into two parts with the bog in the north and the main use area in the south. The bog is the largest one in the lower 48 states and has a mile-long boardwalk through an otherwise inaccessible landscape.

The bog, which has long been a source of medicinal plants for the Ojibwe, 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.

The southern unit in sandwiched between Upper Red Lake and the Tamarac River. Visitors can enjoy a campground with winterized camper cabins, a sandy beach, picnic grounds, and great fishing.
