This route was planned by komoot.
The trail primarily features a crushed limestone and gravel surface, following an abandoned railroad bed. This results in generally gentle slopes, mostly not exceeding a 4% grade. You'll traverse diverse landscapes, including spruce and ponderosa pine forests, meadows, and narrow valleys, with sections skirting mountainsides and crossing creeks. Some areas, particularly the 19-mile stretch from Deadwood to Dumont, can be more strenuous with loose or deep gravel.
There are 15 easily accessible trailheads located along the 109-mile route. These trailheads typically offer amenities such as parking, self-sale trail pass stations, vault toilets, and tables. For example, the Dumont Trailhead is a key access point.
Yes, a trail pass is required for anyone 12 years or older to use the George S. Mickelson Trail. These passes can be purchased at self-sale stations located at the trailheads or online. As the trail is within the Black Hills National Forest, specific forest regulations may also apply, though a separate forest entrance fee is not typically required for trail use.
The trail is open year-round for hiking, biking, and horseback riding. Spring and fall offer pleasant temperatures and beautiful scenery, with autumn providing vibrant colors. While accessible in winter for cross-country skiing and snowshoeing, be prepared for snow and colder conditions.
Much of the trail is considered accessible for people of varying ages and abilities due to its gentle slopes. However, some sections, like the 19-mile incline from Deadwood to Dumont, are more strenuous. Beginners should choose shorter, flatter sections and be aware that some areas may have loose gravel requiring more effort.
You'll pass through spruce and Ponderosa Pine forests. Keep an eye out for diverse wildlife such as deer, elk, turkeys, foxes, and coyotes. Mountain lions are also present in the area, though less commonly seen. The trail also offers a chance to observe autumn colors in season.
Yes, the George S. Mickelson Trail is generally dog-friendly. However, dogs must be kept on a leash at all times, and owners are responsible for cleaning up after their pets. Always ensure your dog is well-behaved and respectful of other trail users and wildlife.
The trail, built on a former railroad line, features over 100 converted railroad bridges and four rock tunnels, including a quiet tunnel break. You'll also encounter natural beauty like a waterfall by Rochford Road and a wooden bridge, as well as remnants of old cabins and abandoned mines, offering a glimpse into the area's gold mining history.
Yes, the George S. Mickelson Trail is a significant route that can intersect with other paths. While it forms the primary path for the komoot tour, sections of the route also pass through or connect with other parts of the George S. Mickelson Trail itself, and briefly with the Deerfield Trail.
The time it takes to hike a section varies greatly depending on its length and your pace. For instance, the specific komoot tour provided covers approximately 33.5 kilometers (20.8 miles) and is estimated to take around 8 hours and 52 minutes to hike, classifying it as a difficult hike. Shorter sections will naturally take less time.
Yes, the trail is open year-round. In winter, it becomes part of the Black Hills Snowmobile Trail System and is also popular for cross-country skiing and snowshoeing. Be prepared for cold weather, snow, and potentially icy conditions, and check local reports before heading out.
