TTFs on TrailRock Garden, Skinny
Technical on either end of this trail.The eastbound direction is a slight uphill. Westbound has a flow sensation to it at speed. Excellent views of Green Valley at the Cliff View Trail on the southeast portion. Both directions in use constantly so keep your eyes forward and watch out for other riders and runners/hikers, especially on the weekends. Some sections just recently re-groomed over this last summer.
