A wonderful addition to a state dominated by water, the Superior Hiking Trail is probably Minnesota's best known trail. It's a 286-mile footpath that follows the rugged ridge along Lake Superior from Duluth to the Canadian border. Thanks to the trail's numerous access points, you can hike for a day or grab your backpack for a multi-day adventure. Pick from 89 backcountry campsites, with no fees, reservations or permits required. Remember: This is a rugged trail, especially for flatlanders. But you won't have to hitchhike back to your car: Several shuttle services are available along the North Shore.
