Tinton Trail
The Tinton Trail consists of around 46 miles of trail that is used for hiking, mountain biking, and running. The trail branches out to several other different trails and overlaps other trails such as the Old Baldy Trail and Rimrock Trail. The main trailhead itself starts off of Tinton Road in Spearfish Canyon and depending on which trail you take differs in difficulty. The trail is especially pretty to hike in the fall.
