San Gabriel Peak

San Gabriel Peak rises from the Transverse Ranges and offers wide views across the Los Angeles Basin toward the Mojave Desert edges. The ascent is demanding and requires proper preparation and physical fitness.

The San Gabriel Mountains received national monument status in 2014 through a presidential declaration to protect the area's natural resources. This marked a significant step in safeguarding the region for the future.

Native American peoples lived seasonally throughout these mountains, settling near water sources that shaped their movements across the landscape. This relationship with the land remains part of how the region is understood today.

Check weather conditions before starting and carry plenty of water, as the mountain is exposed and dry. The route demands sure-footing and good fitness, so plan your time and bring breaks into your schedule.

The peak is made of granite and metasedimentary rocks formed during the Mesozoic era when oceanic plates subducted beneath North America. These rock layers tell a story of continental change spanning millions of years.
