Rock Harbor extends through September 15. See specific stay limits for each campground in the current park newspaper. Permits are required, regardless of group size or method of travel, for all overnight stays at campgrounds, cross country sites, docks, or at anchor. Permits are free for parties of 6 or fewer or boaters.
