Some steep sections (8-12% grade) might require walking for certain riders.
Cyclists often encounter a variety of wildlife. Common sightings include deer, elk, coyotes, and wild turkeys. If you're lucky, you might even catch a glimpse of bighorn sheep or mountain lions, especially in more secluded areas. The diverse landscapes provide habitats for many species.
While the Mickelson Trail itself has its own pass requirements, it traverses through the Black Hills National Forest. Generally, standard national forest regulations apply, such as staying on marked trails, packing out all trash, and respecting wildlife. Always check the official Black Hills National Forest website for the most current and specific regulations regarding camping, fires, and other activities if you plan to venture off the main trail.
