Overview
Josephine Peak stands at 5,558 feet above the La Crescenta-Montrose area, making it one of the more accessible summits in the western San Gabriel Mountains of Angeles National Forest. It doesn't get the press that Mt. Baldy or San Gabriel Peak receive, which is exactly the point. On a Saturday morning when the Eaton Canyon parking lot is overflowing at 7 AM, the Colby Canyon trailhead is quiet.
The route follows the Josephine Fire Road from the base of Colby Canyon up to the summit, a wide, well-graded fire road that climbs steadily without technical sections. Josephine Peak is named for a forest ranger's wife who worked in the area during the early 20th century. A ruined lookout tower once stood here; the concrete foundation is still visible at the top. The summit provides a panoramic view that takes in the San Fernando Valley to the west, the Crescenta Valley directly below, and a sweep of San Gabriel peaks to the east including Mt. Lukens, San Gabriel Peak, and the higher terrain of the front range.
At 5,558 feet, Josephine sits below the snowline most of the year, which is why October through May is the best window. Summer temperatures in the lower canyon can push into the 90s, and the exposed fire road offers little shade above the first mile. October through November and February through April deliver the ideal combination of cool air, clear skies, and manageable crowds.
The Route
Miles 0 to 1.0: Colby Canyon approach. The trail begins at the end of Colby Canyon Road and enters the canyon on a dirt path that follows the creek bed. The canyon is narrow and shaded, with coast live oak and chaparral. The creek is typically dry by late spring but can run in winter and early spring. This lower section is the most sheltered part of the hike.
Miles 1.0 to 2.5: Fire road climb. The trail transitions to the Josephine Fire Road, which begins its ascent in earnest. The grade is consistent and never steep enough to require hands, but it doesn't relent much either. The road is wide enough to walk comfortably two abreast. Chaparral lines both sides: ceanothus, chamise, and scrub oak. As the trail climbs, views begin opening to the south over the Crescenta Valley and the Los Angeles basin.
Miles 2.5: Summit. The fire road ends at the summit flat. The old lookout tower foundation is concrete and overgrown at the edges. Find a spot on the flat to take in the full panorama. On a clear winter or fall morning, you can identify individual neighborhoods in the San Fernando Valley to the west and the Santa Susana Mountains and Santa Monica Mountains beyond. To the north, the higher peaks of the San Gabriel range roll back into the interior. The Verdugo Mountains are visible to the southwest.
Return by the same route. The descent is fast on the open fire road.
When to Visit
October through November is the best window. Air quality improves dramatically as summer marine layer and wildfire smoke clear out. Temperatures at the summit are in the 50s to 65s. The Santa Ana winds occasionally push visibility to an extraordinary level, with downtown LA's skyline visible from the top.
December through February can bring snow to the summit, though rarely more than a few inches that melts within days. Bring an extra layer and check conditions if there has been recent rain, as the fire road clay surface gets slippery when wet.
March through May is also excellent. Wildflowers bloom in the canyon in March and April. Temperatures are mild and the chaparral is green. This is a reasonable hike even for newer hikers in spring.
June through September: Manageable early in the morning but uncomfortable by midday. If you go in summer, start by 6:30 AM and be off the exposed fire road by 10 AM. The shaded canyon section helps on the return.
Practical Details
Parking: The trailhead is reached via Colby Canyon Road off Foothill Blvd in La Crescenta-Montrose. Street parking along Colby Canyon Road; no formal lot. An Adventure Pass ($5/day or $30/year) is required. Arrive by 8 AM on weekends to get a space.
Permit: No wilderness permit or timed entry permit required. Adventure Pass covers access.
Dogs: Allowed on leash. The wide fire road is comfortable for dogs, but bring water for them, especially in warmer months. There is no water source on the route.
Water: No water on the trail. Bring at least 1.5 to 2 liters per person. More in warm weather.
Crowd levels: Much lighter than comparable LA-area hikes. Weekday mornings are essentially solitary. Weekend mornings see a modest number of regulars but nothing like the Eaton Canyon or Mt. Hollywood crowds.
Getting There
From Glendale or Burbank, take the 210 freeway east to the La Crescenta exit or drive north on Foothill Blvd through the Crescenta Valley. From Foothill Blvd, turn north on Rosemont Avenue or Briggs Avenue toward the foothills, then find Colby Canyon Road. The road dead-ends at a gate that marks the trailhead. Drive time from downtown Los Angeles is about 35 to 40 minutes. From Glendale, about 20 minutes. GPS the "Colby Canyon Trailhead" for the most reliable routing; the road is easy to miss on a first visit.
The Bottom Line
Josephine Peak is the right answer when you want a genuine Angeles National Forest summit hike without the crowds and without driving an hour into the mountains. The 5.5-mile round trip with 1,500 feet of gain is accessible for hikers in reasonable shape, and the summit view is better than many more famous options in the range. Go in fall or winter for clear skies and the best visibility across the LA basin.
