Updated February 2019

Popular Upper Las Virgenes and Cheseboro Canyons were hit hard by the 2018 Woolsey Fire, but thankfully the areas have opened and provide hikers a chance to see the recovery. Recent rains have brought out the green in the hillsides – and also made for muddy conditions on some of the trails, particularly in the canyons and a few stream crossings that may be more challenging than usual. The area’s wide network of trails make for many possible routes including the trip described below, which meanders pleasantly along the floor of Upper Las Virgenes Canyon before climbing to an unnamed bump high above Bell Canyon with a 360-degree view. There are many options for extending or shortening the hike as needed.

From the trail head, follow the wide Las Virgenes Canyon Trail north (a single track branches off, making for a more challenging alternative). After crossing a stream, you reach a T-junction. Head left (the right fork heads east toward Lasky Mesa.) About 1.1 miles from the start, you reach another junction with a trail heading east. Continue for another 1.3 mile to a Y-junction with the single-track Sheep Corral trail, a possible return route for a longer loop hike. This route heads right however, onto the unsigned Bell Canyon Loop trail. Now the first major ascent begins as you climb over 600 feet in the next 1.3 miles. As you ascend the views get better and better. At about 3.2 miles from the start, you enter a grove of oaks and cross the top of a waterfall that might be flowing  if there have been recent heavy rains.

At about 3.8 miles from the start, the trail reaches the top of a ridge and descends to another Y-junction. Bear left and descend back into the upper reaches of Las Virgenes Canyon, now heading west. The trail drops almost 200 feet before making the second major ascent. At about 4.6 miles, an obscure, unsigned single-track branches off on the left. This is the continuation of the Bell Canyon Loop Trail, which eventually hooks up with the Sheep Corral trail, leading you back to the junction in Las Virgenes Canyon for a 12-plus mile balloon loop.

After reaching the next bump on the ridge, you then drop to a saddle before making one last steep climb of some 200 feet. The fire road makes a sharp bend to the right and climbs to an unnamed but obvious bump (elevation about 2,000 feet). Here you are rewarded for your efforts with excellent views in all directions. The Santa Monica Mountains stretch out to the south beyond the folds of Las Virgenes Canyon and Cheseboro Canyon while the Santa Susana Mountains lie to the north past Simi Valley.
