After half a decade of planning, some debate, and the solidification of enthusiastic support across a broad spectrum of the public, the Sleeping Bear Heritage Trail will officially launch with a groundbreaking ceremony at the Dune Climb on Friday, August 12 at 11 a.m. When completed, the 27-mile trail will run from the southern edge of Leelanau County, through the Sleeping Bear Dunes National Lakeshore to Good Harbor Bay.
