|
The San Gabriel Mountains have two parallel east-west ranges. The front range is to the south and overlooks Los Angeles and San Bernardino counties. The northern back range is taller and goes from 6,000′ to 10,000′ with Baldy at the top. A general rule is to hike the front range in cooler seasons and the back range in warmer seasons.
Nestled in the Cucamonga Wilderness, in the eastern end of the back range is Bighorn Peak. The trail goes up Icehouse Canyon to Icehouse Saddle. It then follows a ridgeline that connects Bighorn Peak to Ontario Peak. You can hike to either peak or both.

Icehouse Canyon
The Icehouse Canyon Trail runs alongside a creek, featuring cabins, honey-scented blue ceanothus, rocks, and streams. At the start, there is a giant tree whose roots restrain giant boulders. The trail becomes rocky just before it crosses a dry riverbed.
After crossing the creek, you enter the Cucamonga Wilderness area. The trail then gently climbs to a big rock. The way is long, steep, and gradual like a slide, but covered with stable little stones. The trail steadily climbs the side of the canyon until it begins to switchback like crazy below Icehouse Saddle.
Icehouse Saddle
Right below Icehouse Saddle, the breeze seems to carry you up as the trail levels off. From the saddle, you can see all the neighboring peaks.
The ridge connecting Bighorn to Ontario
The pine needle covered Ontario Peak trail hugs the slope beneath the ridgeline. After a mile, you pass Kelly’s Camp. Then you climb through dense shrubs and over logs to the ridge connecting Bighorn Peak to Ontario Peak. The trail along the ridge dips ever so slightly before climbing the slope of Bighorn Peak.
Bighorn Peak
At the summit, soak in views of Cucamonga to the east, Ontario Peak to the west, and SoCal to the south. On this day, there were gray squirrels, chipmunks, a young deer, bumblebees, screeching California scrub jays, and a hooded oriole.
Factoids
Years ago, Bighorn sheep were numerous in the San Gabriels. You may see a few survivors. They named this peak in their honor.
