New opportunities to take in the sights and sounds begin with the June opening of The Waterloo State Recreation Area in Chelsea’s five mile mountain biking, hiking and cross-country skiing trail. The trail, part of a planned 20-mile loop, dubbed the DTE Energy Foundation Trail, was made possible by a $255,000 grant from the DTE Energy Foundation. The trail is the latest update to the Waterloo Recreation Area, the largest state park in Michigan’s Lower Peninsula.
