If you are seeking a mountain bike trail that does not require driving out of town, pedal up to this old mining road. The opening two miles (3.2 kilometers) of loose-graveled switchbacks dominate the ride until you reach the Iowa mine. From there you can either bounce back down, or continue on for the Hunter Creek Loop, which covers just under eight miles (13 kilometers) and returns you to Aspen via Red Mountain Road. Follow residential Smugglers Mountain Road until you reach the well-marked trailhead.
