The Cii Debora Spur Trail provides access to the Temescal Ridge Trail.

Starting at Temescal Gateway Park, Temescal Ridge Trail quickly winds up the canyon before leveling off at the ridge. The trail offers a steep, challenging hike that provides sweeping views of the San Gabriel Mountains, the Santa Monica Bay, and the Los Angeles basin. It is also the route to the iconic outcropping, Skull Rock. To extend the hike, continue along the ridge at the southern end on Temescal Ridge Fire Road.
