Natural tread multiuse singletrack climbing or descending trail in the Willamette National Forest. Narrow bench cut singletrack at the top until the first road crossing at about the 1 mile point. Below that a newly-built section (as of 2016) with banked corners, armored roots and rocks covers most of the second mile of the trail. The remaining stretch of trail extends another 2.5 mi down to the lower trailhead, with stream crossings and a couple of rollable rock drops before it finally flattens out right at the trailhead. ***This trails wet weather resiliency is rapidly declining due to the repetitive use/abuse by shuttlers. Please DO NOT ride the trail in heavy rain, or right after. Heavy rutting and prevalent mud are now a regular thing during wet periods. It needs time to drain and dry out.*** Please stay on the trail and do not create new lines Camping at the trail heads is PROHIBITED AND POSTED! ***

Access Info

Access the top of the trail from Castle Rock above the USFS 480 Rd. The trail also crosses the USFS 480 Rd in its first mile. Access the bottom of the trail from E King Rd on the south side of the McKenzie River, just east of the covered bridge crossing in Rainbow.

Adaptive Bike Info
aMTB Black Rating: Advanced obstacles exist, some trail obstructions.

Plenty of exposed sidehill where adaptive riders will need support. Rock roll near bottom may require spotter. See aMTB3 recommended route.

      It’s a treasure trail. Such a beautiful place to be. As of March 7, 2025 there was about 7 down trees in the flow zone, some were small’ish. Tread was excellent the entire length of trail.

      Really great downhill through stunning forest. Highly recommend starting at the trailhead and taking the pavement to Leary and getting to the top for a very satisfying loop.

      Super fun PEDAL through old growths. I love to shuttle but this place is awful for it as there are plenty of uptight hikers and equestrians for even pedaling...it sucks for everyone if you shuttle. There's a few berms and side hits, no jumps or drops.

      We hope you've been enjoying Trailforks!
