The trailhead is beside the wood fence. This is an out and back ride with a steady climb. Once you get to the wide gravel road, you've reached the top. Turn around, check your brakes and fly like the wind.
How to get there:
In Spearfish head West on Jackson Blvd. Follow the truck route to the P&T Saw Mill and take the first left after the mill onto a gravel road. At the fork in the road, turn right and follow this road to the cattle gate. Turn left here immediately after the gate and park.
