Los Angeles, CA: Ontario and Bighorn Peaks via Icehouse Canyon

Explore the ruins of historic taverns and watch clouds roll over two 8,000-foot San Gabriel peaks on this 14-mile out-and-back in the Cucumonga Wilderness.

Trip Tools

The 7-mile route over Bighorn and Ontario peaks begins in the shade of Icehouse Canyon, where hikers pass through the stone ruins of a 1920s wilderness lodge. The Icehouse Canyon Trail steadily climbs 3,200 feet in the first 5.5 miles of this trip, traveling from a lush creekside environment to coniferous forests to exposed, rocky ridgelines. After only 2 miles, you’ll drop the crowds at Icehouse Saddle and enjoy 360-degree views of nearly every peak in Cucumonga Wilderness.
More views await as you pass the crumbling foundation of another abandoned resort, Kelly Camp, and break through tree cover once again. Big skies offer up a massive panorama of the backside of Ontario, Cucamonga Peak, Bighorn, Timber Mountain, Telegraph Peak, Thunder Peak, Mount Harwood, and Mount Baldy. From the Bighorn Peak Trail, climb up a steep grade with loose talus to Bighorn then take the ridgeline trail 1.5 miles through manzanitas to Ontario. Both summits have a sweeping vista of the evergreen-blanketed San Gabriel Mountains; the tallest peak, Mount Baldy, stands out prominently to the west.
