This extremely scenic run begins and ends at the Circle X Ranch parking lot on Yerba Buena Road. It heads out the Canyon View Trail, crosses Yerba Buena Road to the Sandstone Peak Trailhead, and continues on to the Mishe Mokwa Trail. The route goes past Split Rock and Tri Peaks before turning onto the Backbone Trail, passing close by Sandstone Peak (the highest point in the Santa Monica Mountains), and returns to Circle X Ranch via the Canyon View Trail. This course offers sweeping valley to ocean vistas, as well as views of spectacular rock formations. The trails are mostly well maintained single track, with a few short technical sections.
