Isle Royale National Park

QUICKLINKS:

A Superior Wilderness

Isle Royale’s physical isolation and primitive wilderness challenged human use for centuries; ironically today it has become the Island’s main attraction. Accessible only by boat or seaplane, visitors come to experience this island park through hiking its trails, paddling its inland waterways, exploring its rugged coast, or venturing into the depth of its shipwrecks.

Ranger III

The Ranger III, located in Houghton, Michigan, is the largest ship owned and operated by the National Park Service. Like its predecessors, which carried passengers, the Ranger III’s main function is logistical support of Isle Royale National Park. Today it offers its passengers many amenities not found with other service providers.
