Just a route to get the legs burning in the first half of the route and mostly downhill after the climb!
★ 3.0 • 7 miles • 1,163 ft • 8 • Loop •
A basic Auburn ride that can be added extended further into the recreation area. Good for laps, make sure...

Dried out, overgrown, a few downed trees…dont think they have the man power to maintain this trail

Wow, rode for the first time yesterday and it was AWESOME. Switchbacks you can really dig some tires into and the jumps are fun!.

FATRAC smoothed out most of those annoying roots and rocks in curves. Overall smoother ride, especially at the end. Some drainage gutter is now right where I used to ride, but now can't, on one turn. Not a complaint; just an adjustment. What used to be an OK trail is now a very good one. (I always preferred Stonewall and Confluence)
We hope you've been enjoying Trailforks!
