The Lower Canyonback Trail is more challenging and scenically interesting than its upper counterpart. Purists might be turned off by the fact that this route is almost entirely on fire roads and paved roads and that power lines follow it for much of the way, but the ocean and mountain views are excellent and the hike’s convenient location and dog-friendliness add to its popularity.

A few informal trails branch off and run parallel to the main roads, making several different routes possible. Begin by following the trail uphill, almost immediately coming to a split where a use trail heads up a ridge to the right and the paved road continues to the left, slightly downhill. The two routes rejoin at about 0.4 miles, where you’ll bear left and follow the fire road uphill. (Another trail, popular with mountain bikers, also branches off to the left at this point; it rejoins the main route later on. There’s also a steep break that heads straight up at this point, soon rejoining the fire road). Farther uphill, 0.7 miles from the start, a steep path climbs to a vista point where a wooden bench hangs from a large oak. From this ridge, you enjoy some of the best views of the hike.

The ridge drops back down to rejoin the fire road (1.1 miles) as well as the single-track from earlier. You continue, enjoying good views on both sides, climbing to the highest point on the route (1.7 miles), marked by a large water tank. A short spur on the left leads to a knoll with some nice vistas; the road, now paved, continues, gradually descending through a plateau dotted with oaks, willows and spring flowers. A use trail leads to what someone has named Nipple Mountain, although the area is considered a sensitive habitat and is off limits.

As you descend toward the end of the trail, you may get glimpses of the Santa Susana and San Gabriel Mountains. A metal gate marks the trail’s end at an upscale residential community. It’s possible to access the Upper Canyonback Trail by walking about half a mile on streets; that route continues a mile and a half farther to Mulholland Drive, making a round trip of 8+ miles or a possible 4-mile shuttle with the necessary arrangements.

Big wild was filled with dog walkers, dozens if not hundreds of dogs. Too much!
I tried to hike this Friday, May 28th 2020 and the gate was locked. A local resident said it has been locked for over a week.
Thanks for the heads up, I’ll see if I can find some more info about it.
