The Rimrock Trail in Spearfish Canyon begins in the same area as Little Spearfish Trail, only across the road. From Savoy take FSR222 and follow it for just under five miles. The trailheads to Rimrock Trail and Little Spearfish Trail are on opposite sides of the road. There are also several access points along the way, including the Dances With Wolves film site location, Timon and Rod and Gun campgrounds, the Old Baldy Trail, an old ranger station/root cellar, and several small marked and unmarked trailheads.
Rimrock Trail is a fairly moderate hiking trail. It consists of one large loop that is just over six miles in length, or two smaller loops that are approximately three or five miles in length. If you were to hike the entire trail system, you will have gone through about a 700 foot elevation change throughout.
