If there are sheep in the area, please don't bring your dog.
If starting from Lower Loop or Meadow Loop Trail, follow the sign to this trail along the old narrow guage railroad bed. Zip along this for a few hundred yards, turn right down the switchback to a crosshill trail that gets more challenging. Carefully ride across the small arroyo, down to a water crossing, then back up. There's a coal deposit from the old train days near the switchback. Notice it?
