The San Gabriel Mountains are close enough to feel local
The national monument north of the Los Angeles basin protects more than 452,000 acres of mountains, canyons, history, habitat, and recreation land.
The San Gabriel Mountains give Los Angeles County one of its great outdoor edges. For many neighborhoods, they are close enough for a day trip. They are also big enough to feel like an escape.
The national monument now stretches more than 452,000 acres. Most of it sits inside Angeles National Forest, with a smaller piece reaching into San Bernardino National Forest. The place carries cultural history, geologic features, rare plants and animals, and recreation used by millions of visitors.
Pick your trail, picnic area, or scenic stop first. Then check the Forest Service page for maps, road notes, and seasonal rules. It is close, but it is still mountain country.
