Located in southern California, lies the Angeles National Forest, encompassing 694,187 acres including almost the entire San Gabriel Mountain range. The Forest provides the striking backdrop to southern California's largest metropolitan area, the city of Los Angeles. Topography on the forest ranges from mountain peaks over 10,000 feet to low-lying canyon bottoms at a mere 1,200 feet above sea level. A good introduction to the Forest is a drive along the scenic Angeles Crest Highway (State Highway No. 2). Along the way, see how the vegetation changes with elevation and watch for wildlife-bobcat, mountain lion, bear, and perhaps get a glimpse of impressive Nelson bighorn sheep. The forest offers year-round opportunities for camping, hiking, swimming, boating, picniking, and sightseeing. Over 800 miles of forest trails lead hikers, mountain bikers, equestrians, and off-highway vehicle riders across rugged backcountry, along high, scenic ridges, and through shady, tree lined canyons. During the winter, visitors can ski at one the five ski areas or cross country ski, snow camp, hike, snow-mobile, or just play in the snow.
