Isle Royale National Park

Wilderness Island of Lake Superior

Established in 1940, Isle Royale National Park protects 571,790 acres of wilderness archipelago. The park encompasses one main island, hundreds of smaller islands, and surrounding waters of Lake Superior, creating a unique ecosystem that's home to wolves, moose, and diverse aquatic life.

Known for its wolf-moose predator-prey relationship and pristine wilderness, the park offers visitors a rare chance to experience true isolation. The park's maritime history is preserved in lighthouses and shipwrecks beneath the crystal-clear waters.
