The Cold Stream Trail begins just across CA 79 from the Paso Picacho camping area. Mountain bikers must turn north on the trail. The middle section to the south is clearly marked as off-limits for bikers.<br><br>Cold Stream is a narrow singletrack with lots of turns, dips, and bends with a couple of rocky areas thrown in. Nothing too difficult, just a pleasure to ride. The trail passes through the forest regenerating from the massive 2003 Cedar Fire so there is an interesting mix of partially burned and decaying trees with new growth.<br><br>Cold Stream connects to Los Caballos trail near the paved Stonewall Mine Road by using the Vern Whitaker Trail and Connector, offering connectivity to the mountain bike trails at the north end of the park. Bikes may continue northward on Los Caballos at this intersection, but the southern route towards the horse camp is closed to bikes.
