Starting from the Crescent Mountain, North/South Pyramid Trailhead this loop was done clockwise. See Oregon Endurance Mountain Biking for original route and expanded version. A good majority of this loop is loamy with only a few areas of chunder. See individual trail descriptions for more information. Would make a good bikepacking loop if you don't mind climbing with a loaded bike. Water sources for filtering are roughly at miles 8 and 23.

This is an epic loop. Due diligence required. Suggest completing a couple 5+ hour rides with 7k+ of climbing before attempt. There's water at Scar Mt creek, a spring up high, which is about half way. I carried 1.5l to start, and 1.5l at the spring. Hotter weather maybe more. The switchback climb sections on N Pyramid will kick your ass and come late in the ride so always be thinking about that. The descent of N Pyramid absolutely is double black. Bucket list ride, old school single track epic ride.
