Porcupine Mountain Wilderness - Union Mine Trail

Porcupine Mountain Wilderness - Union Mine Trail is a trail in Michigan, part of the state's vast network of paths for hiking, biking, horseback riding and seasonal use. Michigan maintains thousands of miles of designated trails — from rail-trails and shoreline paths to rugged backcountry routes and groomed winter corridors for cross-country skiing and snowmobiling — threading through state forests, parks and quiet countryside.

Surface, length and allowed uses vary by trail, and many shift with the seasons: soft or muddy in spring, groomed for snow in winter. Check the managing agency for trailheads, maps, current conditions and any required permits or trail passes before heading out. Nearby parks, waters and other trails are listed under related places.
