The San Gabriel Mountains are located in northern Los Angeles County and western San Bernardino County, California, United States.[1] The mountain range forms a barrier between the Greater Los Angeles Area and the Mojave Desert. This Transverse Range lies in and is surrounded by the Angeles National Forest with the San Andreas Fault as the northern border to the range. The highest peak in the range is Mount San Antonio, commonly referred to as Mt. Baldy. Mount Wilson is another famous peak, famed for the Mount Wilson Observatory and the antenna farm that houses many of the transmitters for local media. The observatory may be visited by the public.

The main road that runs through the San Gabriel Mountains is the Angeles Crest Highway, State Route 2. It starts in the southwest at the city of La Cañada Flintridge and ends at its junction with State Route 138 just past Wrightwood near the Victor Valley and the West Cajon Valley. Past its junction with Angeles Forest Highway traveling east, Angeles Crest Highway features blind curves, various bumps, and potholes. This section of the "Crest" is closed during the winter due to rockfall and avalanche hazards. State Route 2 just past Mountain High is called the Big Pines Highway all the way to the 138 junction.

Another key county route which connects Angelenos to and through the mountains is Angeles Forest Highway. Angeles Forest Highway begins 11 miles northeast of La Cañada Flintridge at its Angeles Crest Highway junction. Ending near Acton, it allows easy access to the central Forest and the fast growing Antelope Valley. Because the "Forest" and the 11 mile "Crest" portion leading to La Cañada Flintridge is well traveled by Antelope Valley commuters, its road maintenance is much better, and is open much of the winter.

In the winter snowboarding and snow skiing is quite popular in the San Gabriels at Mountain High, and Mt. Baldy. The two other resorts, Mount Waterman and Kratka Ridge, are rarely open. In the summer, canyoneering, hiking, backpacking, picnicking and camping are some of the activities of its visitors. From time to time, a hiker gets lost or stuck on a mountain ledge, or may fall downhill. Some of the more extreme cases of emergency search and rescue will often be given air time on Los Angeles television and radio newscasts.

Angeles National Forest Fire Lookout Association has rebuilt and operates Vetter Mountain Lookout, and Slide Mountain Lookout. Organization is rebuilding South Mount Hawkins Lookout.
