Porcupine Mts-Cross Trail/Correction Line Trail

The Correction Line Trail and Cross Trail are located in Porcupine Mountains Wilderness State Park. They cross the heart of the park’s old-growth forest and connect the Big Carp River Trail to Mirror Lake. Several travelers combine portions of the Lake Superior Trail and the Big Carp River Trail and return using the Correction Line and Mirror Lake Trail. The Correction Line trail is a single, 2.8-mile loop challenging footpath filled with ridges and old-growth forest terrain. The trail does contain a steep climb when journeying towards Mirror Lake. The Cross Trail is 4.5 miles in length.
