A roadless island wilderness in Lake Superior where wolves and moose coexist in a classic predator-prey relationship.
July–August has the warmest weather, but late June and September mean fewer bugs. Ferries run roughly late May–September.
Very low visitation, but ferry and seaplane seats and backcountry permits can still sell out.
The park closes November–mid-April. Lake Superior fog, cold water and sudden storms can delay boats, and biting flies peak in June–July.
General patterns — conditions vary by year. Check current NPS alerts and road status before you go.
Distances are rough estimates to the closest entrance. Check road and ferry conditions before you go.
Campgrounds inside the park are booked through Recreation.gov, and many fill months ahead.
