“This ride features a steep ascent/descent on fire road and passes near the outdoor location for the M*A*S*H sitcom/movie.”— Lost Justpastnowhere
This is followed with an easy ride out along Crags Road to the location for the M*A*S*H outdoor set. There is about a half mile of singletrack along Malibu Creek just before the M*A*S*H set.
Shortly after the M*A*S*H set, you'll start the long, arduous climb of Bulldog Motorway. Bring plenty of water and prepare for a long grind to the crest of the Santa Monica Mountains. Along the way, you'll enjoy sweeping views back into the Malibu State Park and the Santa Monica Mountains.
Once you reach the top of Bulldog Motorway, turn left onto Castro Peak Motorway and descend to the Corral Canyons Parking area. From there, you can continue following this loop along the Backbone Trail: Corral Canyon Trailhead to Tapia Trailhead which initially is a steep but rewarding climb on a rutted, wind-formed, very grippy rock formation. The reward for this climb is a short descent of the same rock formation.
After that, the Backbone Trail joins the Mesa Peak Motorway for most of the descent down to Malibu Canyon Road. The last mile of the Backbone Trail is a steep, twisting singletrack descent. Enjoy, but watch for hikers. A short segment along Malibu Canyon Road completes the loop.
If you don't like the looks of the rock formation at the start of the Backbone Trail, you can continue a quarter mile on Castro Peak Motorway and then turn left onto the Upper Mesa Peak Motorway section which soon joins the route for the Backbone Trail.
