This scenic and rigorous hike explores the secluded western corner of the San Gabriel Mountains. In the wake of its post-Station Fire re-opening, it is popular with hikers and trail runners. Just a short distance from the northeast edge of the San Fernando Valley, the Oak Spring Trail offers a welcome escape into nature during the fall, winter and spring months.

From the parking area, cross Gold Creek Road to the signed trailhead and begin your ascent. You start off shaded by oaks but soon enter exposed terrain as the trail switchbacks its way up a ridge. At least you are on a north facing slope so with an early start (recommended) the sun won’t be too intense.

As you climb higher you get a good aerial view down into Little Tujunga Canyon, with the Mendenhall Ridge dominating the landscape toward the north. The trail moves to an eastern slope, meaning more sun exposure, making the steep ascent more draining. However, the grade levels out at about a mile and soon after you reach a saddle with a great view of the Valley to the west.
The trail passes by a solitary tree, crosses a fire break and then drops into a meadow, passing through thick bushes of ceanothus flowers (be careful of bees). You then enter the welcome shade of the Oak Spring Trail Camp (1.3 miles). This makes a good resting spot.
Continuing south, the trail crosses a stream (be careful of poison oak) and enters the exposed hillside again, soon climbing up a steep, sometimes rough, break. At the top you follow the trail through a ridge with more ceanothus–and more bees–enjoying wide-ranging views. Finally you reach a four-way junction with a fire road. Follow it briefly downhill to where the single-track branches off south toward Fascination Spring a mile away (an additional destination if you have time and energy). Here you get excellent views of the Verdugo Mountains; if the air is clear you can see Old Saddleback in Orange County and Catalina Island. To the west, you can see the Santa Susana range and with good visibility the western end of the Santa Monica Mountains.

The hike up to the fire road is a substantial workout, but if you want to extend your trip you can do so either by dropping down to Fascination Spring or following the fire road in either direction.
I did this hike today 10/30/21. A nice workout; the trail is in decent shape. The Oak Springs Trail camp doesn’t seem to exist anymore. Also, the hike described here just takes you to the fire road. You have to hike an additional 2.7 miles to make it to the Yerba Buena Ridge. There’s a sign at the junction with Oak Springs Trail and the fire road that says this. Then, if you look at a topo map of the hike and the surrounding area, you’ll see it.
