The Double Trail, located inside the Porcupine Mountains Wilderness State Park, is one of several trails that make up the mountain biking and cross-country skiing trail system in the park. The Double Trail stretches for three miles through the rolling hills of the Porcupine Mountains. The Double Trail is connected to the Union Spring Trail, has easy access to the Triple and Log Camp Trails and can be accessed via the Downhill Ski Area. Mountain biking and cross-country skiing are both allowed on the trail, weather permitting.
