Isle Royale National Park was designed to remain a wilderness. And so it has—a wild place with no roads, few services, many foot trails, and a network of water routes for canoes and sea kayaks.

Isle Royale, 45 miles long and 9 miles wide, sports one hotel for overnighters, the homey, comfortable Rock Harbor Lodge. Beyond that accommodations consist of dozens of rustic campgrounds scattered on the shores of bays and lakes, and along the promontories.
Islands are defined by the water around them. Isle Royale includes a lot of water; its boundary stretches 4.5 miles from any exposed land. Shipwrecks ring the island as grim monuments to rocky reefs and shifting fog. The forest, drenched by rain and frequent mist, stands in spongy carpets of moss and lichen.
Tea-colored creeks pour off the ridges, filling wetlands. Animals include, most famously, wolves, plus moose, foxes, river otters, snowshoe hares, beavers, bald eagles, and loons.
How to Visit
Few visitors make a visit to Isle Royale National Park a day trip. The average stay is four days, no surprise considering the effort and preparation it takes to get here.
Although private boats are allowed, most visitors arrive on ferries from Michigan, via Houghton or Copper Harbor, or from Minnesota, via Grand Portage. Activity centers on Rock Harbor, one of two ferry entry points—Windigo is the other.
Both have visitor centers. From Rock Harbor, trails and water routes stretch the length of the island. The Greenstone Ridge Trail traverses the island’s rocky spine; numerous connecting trails offer a web of hikes. Unusual for wilderness parks, some campsites feature shelters that provide relief from rain and insects.
