Start at the North Fork Park yurt parking lot. Proceed up pipeline trail, till intersects with Cinch trail. Proceed until intersect with Mule Shoe trail, proceed to Mule Ear trail intersect. Proceed till intersection of pipeline trail and then head back to the yurt. Very fun ride. This ride is not for the faint of heart. Lots of climbing, but with every climb there is a downhill and that's fun also.
