This summer, thirty years after a pair of trailbuilders first started flagging a hiking route along the ridges overlooking Lake Superior on Minnesota’s North Shore, the Superior Hiking Trail will be finished—mostly. The final section of the trail, connecting it to the Wisconsin border southeast of Duluth, should be completed by Labor Day. Hikers will then be able to travel from that point all the way to the Canadian border on the trail that has been called one of the best in America. But the work is never done. Hundreds of volunteers will continue to put in thousands of hours each year keeping the trail in good condition.
