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.

      reporter Really good from Waldrop for about .5 miles. The section through staircase is a bit jumbly. Road through to Boy Scout pretty good.

       There's only one short section of trail which qualifies as a double black. The rest is squarely a single black.

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