Soaring high above the Los Angeles Basin, the San Gabriel Mountains also are working lands that provide Angeleños 70 percent of their available open space and 30 percent of their drinking water.
Current recreational opportunities include geological, natural history and cultural interpretation activities, hiking, bicycling, hunting, horseback riding, fishing, picnicking, skiing and off-highway vehicle use.
Leashed dogs are permitted on trails, in the wilderness, in campgrounds and in developed areas. Dogs aren’t allowed inside buildings, in swimming areas and in some cabins.
