The Three Mile campground is three miles from Rock Harbor, and a great place to stay if you're looking for a short day after getting off the ferry. The privy and shelters are just a ways up trails off the main path, creating a little isolation and extra quiet from foot traffic passing through. We saw a fox and a moose while staying here! The trail that connects on either side of the campground is made up of huge rock slabs that are just feet away from Lake Superior, and there's old mining grounds just West of the Three Mile campground that are fun to walk around, just be aware of bees!
