One of the routes to San Gabriel Peak begins on Mount Lowe Road, creating a 3.2-mile round trip hike that climbs 1,050 feet. This trek leaves from a trailhead at Eaton Saddle along Mount Wilson Road and delivers great views the entire way to the summit.
Start hiking up Mount Lowe Road (Mount Lowe Fire Road) where you will be greeted immediately by a head-on view of Mount Markham. On the left side of the wide trail, the mountainside drops away into Eaton Canyon to the east below Mount Wilson and Occidental Peak. The dirt road bends to the right toward San Gabriel Peak and continues gradually uphill to Mueller Tunnel, which cuts through the steep face of San Gabriel Peak.
A short distance beyond the tunnel, which was built in 1942, and 0.6 miles from the start, the trail arrives at Markham Saddle. If you continued straight down Mount Lowe Road, you would reach Inspiration Point and Mount Lowe Trail Camp. To the right there is a cement water tower and a single-track heading west to San Gabriel Peak. Turn right here up San Gabriel Peak Trail. The next 3/4 of a mile are spent weaving up the slope of San Gabriel Peak. The trail carves around several adventurous outcroppings with great views to the south and west where the mountains give way to the city below.
The trail Ts at a saddle half a mile from the top. To the left is Mount Disappointment, whose summit offers a great view of San Gabriel Peak and surrounding mountains. To the right is San Gabriel Peak, the second tallest mountain in the front range of the San Gabriel Mountains (Strawberry Peak is three feet taller).
Turn right and press on for San Gabriel Peak. The trail switches steeply through chaparral before reaching the summit at 6,161 feet, which offers fine views of the lower San Gabriel Mountains. One can see Mounts Baldy, Wilson, and Lowe, and legend has it, Catalina Island is visible on a clear day (though you probably won’t see much beyond Pasadena).
The adjacent Mount Disappointment has clearer views because the mountaintop was leveled and cleared during the Cold War to host a military satellite installation. Mount Disappointment served as an air-defense Nike Missile site. Radio towers and other military installation still stand on the summit. Over a hundred years ago, surveyors gave Mount Disappointment its name. After reaching the top, they realized that the high peak they sought was actually San Gabriel Peak, which is two hundred feet taller.
To get to Mount Disappointment, descend to the saddle at the T in the trail and continue straight to a clearing filled with cement slabs. Follow the paved Mount Disappointment Fire Road up to the summit. This adds about half a mile (round trip) to the hike, and yes the views are different enough to warrant the extra effort.
The round trip distance of this hike to San Gabriel Peak is 3.2 Miles (3.7 if you visit Mount Disappointment). There is an alternate route to the summit from Mount Disappointment Fire Road that starts farther down Mount Wilson Road. This is a slightly longer hike with more elevation gain (1,400 feet vs. 1,050 feet). Subjectively, the route from Eaton Saddle is the more enjoyable of the two. The trail offers better views and packs more into a shorter excursion than the longer and steeper alternative.
This hike down Mount Lowe Road begins from an amenity-free trailhead within the Angeles National Forest where an Adventure Pass (day use pass) is no longer required. Dogs and mountain bikes are welcome. No fee or permit is required to hike to San Gabriel Peak, so get out and enjoy!
To get to the trailhead: From the 210 Freeway in La Cañada Flintridge, head northeast on Angeles Crest Highway (CA 2) for 14 miles and turn right on Mount Wilson Road Box Road (after mile marker 38). Drive 2.3 miles to the Markham Trailhead at Eaton Saddle and pull into the dirt lot on the right at the start of Mount Lowe Road.
