Trailheads

The Rock Harbor Trail can be busy because it leads to one of the island's main transportation hubs, Rock Harbor. This section between Rock Harbor and Three Mile offers picturesque views of the Rock Harbor Channel and the outer islands. The Rock Harbor Trail begins past the Rock Harbor Campground. Much of this trail transverses over rocky outcroppings and it can be difficult to find secure footing. Cairns (rock stacks) are placed on open ridges to mark the way.

After hiking about 1.8 miles from Rock Harbor the trail cuts into the woods and arrives at the trailhead for Suzy's Cave. Suzy's Cave is an inland sea arch carved by waves when Lake Superior's shoreline was higher. Past Suzy's Cave is the junction with the Tobin Harbor Trail and Mount Franklin Trail.

The Rock Harbor Trail continues along the shoreline for about another 1.8 miles to Three Mile Campground. Three Mile Campground is located right on the shore. Campers enjoy the sounds of water lapping the shoreline while relaxing at camp in the evening.
