The South Mirror Lake Trail, is one of two trails that encircle the famous Mirror Lake of the Porcupine Mountains Wilderness State Park. The Southern Loop is the shorter of the two loops, as it is only 3 miles. Along this trail, visitors will find several backcountry campsites and cabins scattered throughout. Most hikers combine the South and North Mirror Lake Trail to cross through the heart of the Porcupine Mountains, beginning at Summit Peak Road and ending at the Lake of the Clouds overlook.
