This section of the Mickelson trail begins12 miles north of Hill City on Mystic Road and is within the Black HIlls National Forest. You'll travel alongside Castle Creek and Rapid Creek as you make your way to the historic mining town of Rochford, and then you'll pass by Swede Gulch before getting to the Dumont Trailhead. You can make this a half-day one way trip with a vehicle at each trailhead, or you can make it a full-day out and back trip. Be sure to purchase a Mickelson Trail pass at a self-service station along the trail or online.
