Land OwnerBoulder County Parks & Open Space
Fast and flowy through the trees. The Ponderosa Loop sits on top of a mesa and is accessible either from the south via Left Hand canyon and the Wapiti trail or from the north via Lyons and the Picture Rock trail. The Boulder Mountainbike Alliance has done extensive rock armoring on the trail to protect the natural habitat.

Awesome trail! A lot of work put into excellent rock work! Must ride trail system!

Such a fun trail. You have to work for your speed at the beginning and some of the corners are a bit flat and loose but they have more grip than you think. Definitely best when ridding clockwise.

I ride this trail a few times a week for a lunch break. This is not a black. I'd give it a blue-green rating. A few little spots, but pretty easy.
We hope you've been enjoying Trailforks!
