This hike explores the rugged terrain of Rocky Peak’s back side. It starts in a gated community and climbs to the Rocky Peak Fire Road, about a mile north of the summit.

Unless you have access to the Indian Springs or Fern Ann Falls communities, your hike will begin outside the guard house on Iverson Rd. Head north from under the freeway to the pedestrian gate, where you can ring a buzzer on the side for access. Inside, pick up the Santa Susana Pass Trail as it heads north along Iverson. At 0.3 mile, it leaves the road and threads its way between houses, crossing Fern Ann Falls Rd. at 0.6 mile. At 0.7 mile, leave the Santa Susana Trail and head northwest on Indian Hills Road. It climbs steeply uphill for 0.2 mile to an unsigned junction; this is the start of the Johnson Mountain Way. Bear left and follow a Johnson Mountain Way which starts as gravel and soon becomes a rocky fire road. The steady uphill climb continues before leveling out at a ridge line, with Rocky Peak dominating the western landscape and Oat Mountain to the east.

You pass by two spurs on the right leading to an antenna facility and the trail enters an interesting jumble of sandstone and granite boulders. Though still nominally a fire road, Johnson is basically a single-track by this point. Despite being only a few miles from civilization, this part of the trail feels pleasantly remote.

At 2.4 miles, a saddle-shaped rock on the left side of the trail provides a nice place to rest and enjoy a view of Chatsworth. The trail follows the stream bed of Falls Creek, a tributary of Devil Canyon and makes one last climb before leveling out and meeting the Rocky Peak Fire Road, 3.3 miles from the start. Here, you can take in a panorama of Simi Valley to the west. This makes a good turnaround point for a day hike, although if you have time and energy you can head left (south) and continue to Rocky Peak. If you’ve set up a car shuttle at the Rocky Peak trailhead, you can descend via the fire road.
