The George S. Mickelson Trail, in the heart of the beautiful Black Hills, was completed in September of 1998. Its gentle slopes and easy access allow people of all ages and abilities to enjoy the beauty of the Black Hills. Much of the trail passes through National Forest Land, but there are parts of the trail that pass through privately owned land, where trail use is restricted to the trail only.

The trail is 109 miles long and contains more than 100 converted railroad bridges and 4 rock tunnels. The trail surface is primarily crushed limestone and gravel. There are 15 trailheads, all of which offer parking, self-sale trail pass stations, vault toilets, and tables.
