About this Hike
Mileage: about 3.8 miles (via Rock Harbor and Tobin Harbor Trails)
Rocks and roots on trail
Windigo via Greenstone Ridge Trail
Spend a day exploring Suzy's Cave on Isle Royale National Park. Follow the Rock Harbor Trail 1.8 miles beyond the Rock Harbor Campground and turn inland at the wooden post directing you to Suzy’s Cave. Discover an inland sea arch, formed by wave action some 4000 years ago when lake water levels were higher. From here the trail leads on to the gentler Tobin Harbor Trail, which loops back to Rock Harbor. As you meander through a thick canopy of spruce, fir, and birch, watch moose and other wildlife.
