Like middle children, the Puente Hills are often overlooked. Indeed, on hot and hazy summer days, they are not an ideal destination, but on cool winter days when the air is clear their strategic location provides some of L.A.’s best views. Although you will have to contend with power lines for much of this route, you will also get to see almost every major mountain range in southern California. If visibility is exceptionally good, sharp-eyed hikers may even pick out the Hollywood sign.

From the parking area, bypass the fence and head uphill on the Elderberry Trail, a steep fire road (listed on Google Maps both as Rose Hills Road and Skyline No. 2 Fire Road). In 0.4 mile, you reach a junction with the Worsham Ridge Trail, another fire road. The loop can be done in either direction but by going counter-clockwise, the bulk of the ascent happens on the pleasant, partially shaded single-track, not the exposed ridge. The Worsham Ridge Trail descends to the west, taking in views that may extend to downtown L.A. and the Santa Monica Bay, before bending around to the south, passing by some homes. Non-native plants, including eucalyptus trees and (following rains) mustard flowers similar to those at Chino Hills State Park, dominate the landscape.

Next is the Worsham Canyon Trail, a single-track which meanders pleasantly uphill for the next 1.6 miles, picking up a modest 400 feet of elevation gain. Though the vegetation doesn’t provide much cover, the folds of the canyon tend to block out most of the sun, so there’s a decent amount of shade. At about 2.7 miles from the start, you reach the top of the canyon and a junction with the Skyline Trail. Turn left and follow it uphill to a knoll called Workman Hill (the high point of the hike, at about 1,300 feet). Despite the power lines, the views of Mt. Baldy and Old Saddleback are impressive. You also may see distant San Bernardino and San Gorgonio if the air is clear.

From this bump on the ridge, head downhill to a junction where the Skyline Trail heads right toward an alternate trail head on Turnbull Canyon Road. From here, it’s all downhill, half a mile back to the Elderberry Trail where you will retrace your steps back to the parking area.
