Trail is Under Construction and Closed. This is a two year project with completion planned for 2017.

Please don't ride or hike the trail until it is open. Thanks for your patience!
If you'd like to ride, join an Evergreen work party:
We'll ride up to the top, stash our bikes, get some work done and ride down.

Big views, big vert, just outside North Bend

The Olallie Project is secured and funded, with Evergreen crews currently working on site. The trail starts near Rattlesnake Lake, just a few minutes outside of North Bend and only 40 minutes from Seattle.

The first several miles amble up Cedar Butte through pristine forest, then turn east and ascend the flanks of Mt. Washington. There is a cliff along the trail, with multiple opportunities for stunning views. The trail then changes to road-trail conversion before climbing a rock cliff that will be difficult to build, but will be a stunning section of trail. This connects to another road-trail conversion section, before finishing on singletrack just below the summit of Mt. Washington.

Boxley Blowout historical site. The Olallie trail starts at Cedar Butte. Just to the SW of Cedar Butte is the site of the Boxley Blowout of 1918 and some interesting geographical features.

Access Info

Riders will park at Rattlesnake Lake and pedal 2.5 mostly level miles to the trail head via the John Wayne (aka Iron Horse) trail. The start on Olallie trail will be on your right. From there the trail is an out-and-back heading up Cedar Butte and up to near the top of Mount Washington at 3700 feet. As an out-and-back route finding will be easy.
