Discover more about San Gabriel Mountains National Monument

The San Gabriel Mountains National Monument, established in 2014 and expanded in 2024, encompasses over 452,000 acres of the Angeles and San Bernardino National Forests. This natural haven is a vital recreational and ecological resource for Southern California. Millions of residents and visitors seek respite in its cool canyons, perennial streams, and snow-capped mountains. The monument's history stretches back millennia, with over 600 archeological sites evidencing the presence of Native American cultures. Later, Spanish missionaries, Mexican rancheros, and Euro-American settlers shaped the region. In 1892, President Benjamin Harrison established the San Gabriel Timberland Reserve, recognizing the importance of the mountains' watershed. The monument boasts diverse flora and fauna, including over 500 native plants and fungi. Iconic species like the California condor, Nelson's bighorn sheep, and California spotted owl find refuge here. The area also features four wilderness areas: Magic Mountain, Pleasant View Ridge, San Gabriel, and Sheep Mountain. Visitors can enjoy a wide range of activities, including hiking, camping, fishing, and scenic driving. Popular destinations include Mount Baldy, Strawberry Peak, and the Bridge to Nowhere. The Angeles Crest Scenic Byway offers breathtaking views, and the Mount Wilson Observatory provides a glimpse into astronomical research. Despite its natural beauty, the monument faces challenges such as heavy visitor use, leading to trash and sanitation issues. Efforts are underway to improve access, enhance water quality, and protect the fragile ecosystem.
