Rock Harbor Campground — Isle Royale National Park

Rock Harbor Campground offers several amenities, making it the most established campground on Isle Royale. The facilities include potable water on tap, outhouses within the campground, and access to flush toilets at the nearby port. A small store provides camping supplies, food items, beverages, and souvenirs. There's also a small café for hungry hikers. Additional amenities include a ranger station for information and assistance. The campground's proximity to the port makes it convenient for accessing these services before departing the island.

Rock Harbor Campground is considerably busier than Three Mile, as it serves as most visitors' final stop before taking the ferry back to the mainland. It offers more amenities including a store, café, and access to flush toilets at the port, while Three Mile has more basic facilities. Rock Harbor features multiple shelters and tent sites with nearby water access. Wildlife viewing opportunities exist at both locations, with Rock Harbor known for a resident bull moose that frequently appears at various hours. Rock Harbor provides more conveniences but less solitude compared to Three Mile's more remote setting.

Rock Harbor Campground is accessible by ferry service. Visitors can take a ferry from Grand Portage, Minnesota to Windigo and then hike approximately 40 miles across the island via the Greenstone Ridge Trail to reach Rock Harbor. Alternatively, you can take a direct ferry to Rock Harbor from the Upper Peninsula of Michigan. The campground is located right outside the Rock Harbor port, making it convenient for arrivals and departures. Since Isle Royale is an isolated national park, all access is by ferry or seaplane, and advanced planning is essential.

Rock Harbor Campground features nine shelters available at no additional cost beyond the standard camping fee. These shelters operate on a first-come, first-served basis, with availability varying by season and day of the week. They can be particularly welcoming after long hikes across the island. Additional shelters can be found a short distance up the trail from the main campground area, providing options if the weather turns bad. While sometimes in demand, shelters can be shared when necessary, especially during busier periods. These three-sided structures offer good protection from the elements while still providing an outdoor experience.
