The George S. Mickelson Trail is a 109-mile rail-to-trail route that runs the length of the Black Hills, from Edgemont in the south to Deadwood in the north. It follows an old railroad bed, which means grades are gentle, usually four percent or less, and the surface is crushed rock suited to most bicycles. Along the way it crosses more than a hundred bridges, passes through four tunnels and visits Custer, Hill City and other small towns. You can ride a short section from any trailhead, and the most popular sections for visitors are around Hill City and Custer. A trail pass is required, about five dollars per person per day or about twenty dollars for the year, and it must be carried with you. Park entrance licenses do not cover the trail. Rental bikes and shuttles are available in several towns, and e-bikes are a popular choice for those who want help with the distance. A private guided ride with a brewery stop is also available for visitors who want a curated day. Confirm current pass prices and trail conditions before you go.
The trail's appeal is its easy grade and its scenery. Because it follows a railroad, it avoids the steep climbs that make other Hills rides punishing, and the route winds through ponderosa forest, meadows and canyons. The bridges and tunnels add variety, and the small trailhead towns offer a chance to stop for coffee or lunch.
A half-day ride is manageable for most fit adults and many older children, and the whole trail is a multi-day adventure for cyclists who want a challenge. Hikers and runners use it too, and in winter parts of it are used for snowshoeing.
To plan a ride, choose your section and your transport. Many visitors ride downhill from a higher trailhead and arrange a shuttle back, which keeps the effort low and the scenery high. Others rent bikes in town and ride out and back. Bring water, snacks, a spare tube and a rain layer, since weather changes quickly in the Hills.
The trail is open year-round, but the surface can be muddy after rain, and winter conditions vary. Buy your trail pass at a trailhead or online, carry it on your person and respect the honor system that keeps the trail running.
Think about who it suits. Cyclists of all levels, families with older children and visitors who want to see the Hills at a slower pace will enjoy it. A guided private ride suits those who prefer logistics handled, and the brewery stop turns the day into a social outing.
The trail pairs naturally with the 1880 Train, which follows a similar corridor, and with a night in Hill City or Custer. It is a quieter way to experience the region, away from the road traffic, and it rewards visitors who allow a full morning rather than rushing a short section between stops.
