If you like techy rock riding you will love this trail, if not, you will hate it. Best ridden from the Brainard Lake area as a downhill but can be ridden from Peak to Peak if you enjoy steep technical climbing. This could also be done as a shuttle in a number of different ways. Probably the most technical "legal" trail in Boulder County.
This trail is also open to fat bikes in the winter.

Overall grade is low but steady. Lots and lots of rocks on the upper part. Watch for hikers on the weekends.
