Duncan Bay Campground — Isle Royale National Park

Managed by the National Park Service, Duncan Bay Campground sits on Isle Royale, an isolated island in Lake Superior accessible only by boat or seaplane. The campground operates under a no-pets policy, standard for national park backcountry sites. Campers reach the island through ferry services from Grand Portage, Minnesota, or Copper Harbor, Michigan, with advance reservations required for both transportation and camping.

The remote location means no vehicle access once on the island—all gear must be carried from boat landings. Rock Harbor Campground — Isle Royale National Park lies 1.6 miles east for those comparing island camping options. Plan for wilderness conditions with limited facilities and pack accordingly for the multi-day commitment required to reach this Lake Superior destination.
