About
Three Mile Campground is a remote backcountry camping destination located on Rock Harbor Channel within Isle Royale National Park, Michigan's wilderness island in Lake Superior. The campground is accessible via the Rock Harbor and Mount Franklin Trails, as well as by water via kayak, canoe, or private boat. The site features 8 shelters available on a first-come, first-served basis, along with 3 group tent sites that require advance reservation for parties of 7 or more. The campground provides essential backcountry amenities including food storage lockers (required under park regulations to prevent wildlife interactions), seasonal composting toilets, and non-potable water. Boats can overnight at the dock, which has a depth of approximately 9 feet under normal conditions. The terrain throughout the campground is uneven and rough, and facilities are not accessible for those with mobility limitations. Due to the park's stay limit regulations, campers are restricted to 1 night at Three Mile Campground during the peak season from June 1 through September 17. Only self-contained stoves are permitted; ground fires are not allowed. All visitors must follow park regulations including quiet hours from 10:00 p.m. to 6:00 a.m. EDT, and pets are not permitted anywhere in the park. The campground operates seasonally when Isle Royale National Park is open to visitors, typically mid-April through mid-September.
