San Gabriel Mountains National Monument

The National Monument is the heaviest used area on the Angeles National Forest, which receives more than 4 million visitors per year. This number is expected to increase now that the area has been designated a national monument. Hiking, biking, horseback riding, off-highway vehicle use, fishing, hang-gliding, hunting and picnicking are just a few of the recreational activities on the monument.

What Will I See?

Deep canyons, many with perennial streams, provide crucial habitat for rare and unique wildlife, including the California condor, spotted owl, bighorn sheep, and 1,000-year-old limber pines.
