This route was planned by komoot.
The trail's surface is primarily crushed gravel and limestone, which is generally well-maintained. While gravel grinders or e-bikes are ideal, mountain bikes are also suitable. Some riders even use road bikes with 28c tires, though all-terrain tires might be needed for certain rougher sections.
You'll encounter over 100 converted railroad bridges, some with impressive trestles, and four historic rock tunnels. A notable one is the 40-foot-long 'keyhole' tunnel south of Mystic. The trail also passes through areas rich in gold rush history. Specific sections include the George S. Mickelson Trail between Rochford and Mystic, George S. Mickelson Trail between Mystic and Redfern, and George S. Mickelson Trail between Redfern and Hill City.
Yes, the trail is generally considered easy-going with mellow grades, making it suitable for leisure cyclists, beginners, and families. Most of the route rarely exceeds a 4% grade. However, be aware that the northernmost 16 miles between Deadwood and Dumont involve the longest and steepest climb, with some sections reaching over 9%.
The trail is popular for biking in the warmer months, typically spring through fall, when the weather is most pleasant. It's open year-round, and in winter, some sections can be used for cross-country skiing, snowshoeing, or snowmobiling.
Yes, a trail pass is required to use the George S. Mickelson Trail. You can purchase these at self-sale stations located at the 15 trailheads along its length.
Yes, the George S. Mickelson Trail is dog-friendly. Please ensure your dog is kept on a leash and that you clean up after them to maintain the trail for everyone.
There are 15 easily accessible trailheads along the trail's length, all offering parking, self-sale trail pass stations, and vault toilets. Many also provide drinking water, warming shelters, and picnic areas. Shuttle services are available from various local businesses, which can be helpful for point-to-point rides.
You'll experience diverse and picturesque scenery as the trail winds through the Black Hills National Forest. Expect beautiful spruce and pine forests, rugged canyons, scenic valleys, sweeping meadows, and colorful granite outcrops. Wildlife sightings are common and can include deer, elk, coyotes, and wild turkeys.
Yes, while the route primarily follows the George S. Mickelson Trail, it also passes through small sections of Forest Road 245, Horse Creek Road, Bloody Gulch Road, Forest Road 242, Forest Road 231.1A, Forest Road 241, Forest Road 389.1A, and Forest Road 231.1B.
The trail provides an immersive way to experience the heart of the Black Hills, passing through or near several small towns like Deadwood, Lead, Hill City, and Custer. These towns offer various amenities, including accommodations, cafes, and other services for riders.
While the trail generally has mellow grades, riding from north to south (starting near Deadwood and heading towards Edgemont) is often considered easier. The northernmost 16 miles between Deadwood and Dumont are the steepest climb, so riding this section downhill from Dumont towards Deadwood can be a more relaxed start to your journey.
