The Waterloo-Pinckney Hiking Trail west of Ann Arbor, Michigan, is a 36-mile, 3-day trail. It travels between Big Portage Lake Day Use Area and Silver Lake Beach and affords recreational opportunities to hikers, mountain bikers (26 miles of hiking trails are open to mountain biking, including the very-challenging Potawatomi mountain bike loop), horseback riders, geocachers, and cross-country skiers.
