Cucamonga Peak is one of the highest peaks of the San Gabriel Mountains in San Bernardino County, California, with a summit elevation of 8862 ft. It is within the Cucamonga Wilderness of the San Bernardino National Forest. It is named after the 19th-century Mexican land grant, Rancho Cucamonga, that was below it.

Geography

The mountain towers over the Inland Empire cities of Rancho Cucamonga, Ontario and Fontana. The summit can be seen west of Cajon Pass on Interstate 15, the route from Southern California to Las Vegas. The peak can also be seen on extremely clear days from Mount San Jacinto 46 mi to the southeast, Irvine 55 mi to the south, and Santa Monica to the far west.

Recreation

The most popular trail to the summit begins in Icehouse Canyon. A Forest Service trail (7W07) leads from here to Icehouse Saddle, from which the Cucamonga Peak Trail (7W04) leads to the summit. The round trip is 14 mi long with an elevation gain of 4300 ft. A wilderness permit for vehicles is required. It is advisable to bring a warm jacket or windbreaker as there is no protection from the elements when getting close towards the summit. Snow can also be found in certain parts of the hike depending on the season.
