Phase One of the Heritage Trail, a paved, 10-foot-wide multi-use trail, which runs from the Dune Climb to Glen Arbor, is the first leg of what supporters envision will one day be a 27-mile trail from the Leelanau-Benzie County Line running north to Good Harbor Bay. Though it has been operational for over a month, the Heritage Trail’s official grand opening is scheduled for June 20 at 1:30 p.m. at the Sleeping Bear Dune Climb.
