In addition to the spectacular beauty of this area, its numerous recreational opportunities, and rich cultural history, this group of 21 islands (and 12 miles of mainland) also offers a unique bio-diversity to explore. There are primitive campsites available with advance reservations and permits are required. Permits must be picked up in person at the lakeshore's headquarters visitor center located at 415 Washington Avenue in Bayfield, Wisconsin. This campground is closed during the offseason. There are no electric or water hookups at the campgrounds.
