Access via the (private) 'FAA Road' to the summit is now closed for construction in the area. You can use the 'Quarry Road' to enter the area, but please don't block the road.
E-bikes NOT allowed on Trail 1
Trail 1 at Cline Butte is accessed by climbing the forest road from Cline Falls Rd. to the summit of the tallest (southernmost) butte. You can also climb up the XC trail for a more single-track route to the junction.
Starting at the summit, the trail quickly drops over 700′ in under a mile. The turns are steep, loose, and most include a black-diamond garden of sharp rocks that has to be negotiated (or walked) — a dropper post is probably mandatory unless you’re some kind of psycho. Knee pads are good idea too.
Once you cross Trail 2 (which is an option from here if you like big dirt-jump doubles) you can fly down some single and double track back to the forest road for another lap.
This trail is maintained by Central Oregon Trail Alliance.
