"The drawing of this route may make it look like an out-and- back; however, it is anything but. It involves a very tough fire-road ascent, followed by a bomb down the singletrack that parallels the fire road. This is the bread-and- butter proving ground of Westside XC riders, affording plenty of aerobic and technical challenges. The ride’s centralized location and modest length make it an ideal alternative to visiting a sweaty, crowded gym after work."

"Sullivan Canyon is one of the gems of the eastern portion of the Santa Monica Mountains. Stately oaks and sycamores shade a seasonal creek and a fine trail travels the length of the canyon. The canyon was very attractive to its former owner—the Los Angeles County Sanitation District—and was long near the top of the list as a potential landfill site. Protests by environmentalists derailed the dump and these days Sullivan Canyon is a beautiful place to roam. Sullivan’s high and narrow canyon walls display handsome sandstone outcroppings, as well as a blue-gray bedrock known as Santa Monica slate. During winter and spring, the canyon walls are colored with clusters of ceanothus. Casual hikers will enjoy a nearly flat stroll for a mile or three along the canyon floor. More energetic hikers will make a loop trip by climbing out of the canyon and traveling Sullivan’s west ridge. Views from the ridge are quite good."
"Despite being so close to West Los Angeles, this route provides some of the best scenery and singletrack action that the Santa Monica Mountains National Recreation Area has to offer. The technical and aerobic difficulty is moderate, but novice riders may find themselves winded early—a simple out-and-back up Sullivan Canyon or to the Nike Missile Base via the West Mandeville Fire Road (known locally as Westridge) may be more desirable than riding the full length of the described route."

I have been doing this ride for years and it remains one of my favorites. Slightly technical ascent and descent. The trip up gets difficult at the end so pace yourself, but once to Mulholland you open to a variety of terrain. The trip down Sullivan is fast and fun. This is a great ride for beginner to advanced intermediate riders. Watch out for hikers, dog walkers and folks heading up when bombing down!
