Extension Mill Road

Extension Mill Road is a short, easy 4WD trail through open meadows and dense woods. At the northern trailhead are the remains of the Extension Mill. It is part of the Golden Horseshoe trail system which covers over 8,000 acres between the Swan River and French Gulch. The area has a rich history and is dotted with countless mines, mills, and cabins dating from the late 1870s through the 1950s. The Golden Horseshoe is crisscrossed with 4WD, ATV, single track, mountain bike and foot trails. Keep a sharp eye out for other folks using this network and, as always, be considerate. Stay the trail, and pack out what you packed in.
