Isle Royale National Park
Last Updated: March 2026
Overview
About This Park
Isle Royale National Park is open for the season (April 16–October 31). Main rule: no private vehicles on the island; access is by ferry or seaplane, and backcountry camping requires permits.
Why Visit
Isle Royale spans a vast slice of Lake Superior, a landscape shaped by expansive water and rugged forest. The island’s scale demands deliberate planning and self-reliance, as there are no roads and facilities are sparse. The park centers on a predator–prey dynamic between moose and wolves, a true wilderness where food storage and self-sufficiency determine your success.
