Pretty steep climb/DH depending on what direction you are going. Really rocky and technical, used to access the other trails in the surrounding area. Overall, pretty sweet trail
Access Info
Park/ride to the hospital parking lot. Go to the far end and find the start of the trail at the back. Follow it left and you will be greeted with one heck of a climb.
