"The 277-mile (365-kilometer) Superior Hiking Trail, which hugs a ridgeline above the Lake Superior shoreline between Duluth and the Ontario border, is the best long hike in the country between the Continental Divide and the Appalachian Trail. It covers rugged terrain—bluffs, cliffs, and the spine of the ancient Sawtooth mountain range—as it traces streams and skirts wild rivers, rises to mighty bluffs overlooking the great lake, and plunges into deciduous forests of birch, aspen, and maple interspersed with redolent stands of boreal spruce and balsam."
