TTFs on TrailRock Garden
Fat Lip is not heavily ridden, and can get overgrown from August-Snowfall.
This trail is the route to take you from Keystone to Black Forest. It is tight and a bit overgrown in places, but a fun trail to maneuver over roots and around tight turns. A lot of this trail is narrow bench cut on steep faces. It's a difficult climb and descent technically for this reason. There are 2 climbs, one near the start and a more difficult one (steeper) in the 2nd half (South).

I enjoy tight techy trails and thought this one was cool. I liked it. And it got me over towards Black forest which was the objective.

Trail can be pretty technical in spots with some tight squeezes between trees.

Older style “true” single track that should be classified intermediate difficulty when dirt is good. A couple short steep climbs and short steep descents. If you like John’s area and stuff south of there, this will be fun. Use this as a loop from shadow lake area involving 9k/Apex/Keystone. Technical areas similar to lower Keystone in trees.
We hope you've been enjoying Trailforks!
