Very solid route. Not too terrible elevation. Most of the singletrack parallels forest service roads so if you want to save some gas for later you can bail on a section and still stay on route.

The section EZ Out is the most technical singletrack on the route.

Not many views except near the top of Observatory Hill

We hope you've been enjoying Trailforks!

A new metal bridge has been added at the creek at the bottom. The old trail has been blocked off where the old stream crossing was.
