The Angeles National Forest (ANF) of the U.S. National Forest Service is located in the San Gabriel Mountains of Los Angeles County, southern California, United States. It was established on July 1, 1908, incorporating the first San Bernardino National Forest and parts of the former Santa Barbara and San Gabriel National Forests. It covers 655,387 acres (1,024.0 sq mi; 2,652.3 km2) and is located just north of the densely inhabited metropolitan area of Los Angeles. A small part extends eastward into southwestern San Bernardino County, in the Mount San Antonio ("Mount Baldy") area. A tiny section also extends westward into northeastern Ventura County, in the Lake Piru area. Forest headquarters are in Arcadia, California.
The Angeles National Forest manages the habitats, flora and fauna ecosystems, and watersheds. Some of the rivers with watersheds within its boundaries provide valuable non-groundwater recharge water for Southern California. The existing protected and restored native vegetation absorb and slow surface runoff of rainwater to minimize severe floods and landslides in adjacent communities. The land within the Forest is diverse, both in appearance and terrain. Elevations range from 365 meters to 3,067 m (1,200 to 10,064 ft). The Pacific Crest Trail crosses the forest.
A National Forest Adventure Pass is required for parking at many locations in the Angeles National Forest and other National Forests in Southern California, and this can be obtained online or from visitor centers and local merchants. Los Angeles County has declared that passes are not required on county-maintained roads. There are also many other areas that do not require the pass.
