Glidden Lake is on Lake Mary Road, south of M-69 about five miles east of Crystal Falls. There are three loops (3.4, 4.5 and 3.9 miles) to these well-marked trails with signs every half mile. The starting point is in the parking area adjacent to Glidden Lake. Cool off after your hike or bike with a dip in Glidden Lake. There’s a small sandy beach just off the parking area. The facility is part of the Copper Country State Forest managed by the Michigan Department of Natural Resources and Environment.
