The San Gabriel Mountains are a mountain range located in northern Los Angeles County and western San Bernardino County, California, United States.

The range lies in, and is surrounded by, the Angeles and San Bernardino National Forests, with the San Andreas Fault as its northern border.
The Santa Clarita Valley (SCV) is part of the upper watershed of the Santa Clara River in Southern California. The valley was part of the 48,612-acre (19,673 ha) Rancho San Francisco Mexican land grant.

State Route 14 is a north–south state highway in the U.S. state of California that connects Los Angeles to the northern Mojave Desert. The southern portion of the highway is signed as the Antelope Valley Freeway. The route connects Interstate 5 on the border of the city of Santa Clarita to the north and the Los Angeles neighborhoods of Granada Hills and Sylmar to the south, with U.S. Route 395 (US 395) near Inyokern. Legislatively, the route extends south of I-5 to SR 1 in the Pacific Palisades area of Los Angeles; however, the portion south of the junction with I-5 has not been constructed. The southern part of the constructed route is a busy commuter freeway serving and connecting the cities of Santa Clarita, Palmdale, and Lancaster to the rest of the Greater Los Angeles area. The northern portion, from Vincent to US 395, is legislatively named the Aerospace Highway, as the highway serves Edwards Air Force Base, once one of the primary landing strips for NASA's Space Shuttle, as well as the Naval Air Weapons Station China Lake that supports military aerospace research, development and testing. This section is rural, following the line between the hot Mojave desert and the forming Sierra Nevada mountain range. Most of SR 14 is loosely paralleled by a rail line originally built by the Southern Pacific Railroad, and was once the primary rail link between Los Angeles and Northern California. While no longer a primary rail line, the southern half of this line is now used for the Antelope Valley Line of the Metrolink commuter rail system.

The Tejon Pass, previously known as Portezuelo de Cortes, Portezuela de Castac, and Fort Tejon Pass is a mountain pass between the southwest end of the Tehachapi Mountains and northeastern San Emigdio Mountains, linking Southern California north to the Central Valley. Both the pass and the grade north of it to the Central Valley is commonly referred to as "the Grapevine". It has been traversed by major roads such as the El Camino Viejo, the Stockton – Los Angeles Road, the Ridge Route, U.S. Route 99, and now Interstate 5.
The Ridge Route, officially the Castaic–Tejon Route, was a two-lane highway between Los Angeles County and Kern County, California. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Much of the old road runs through the Angeles National Forest, and passes many historical landmarks, including the National Forest Inn, Reservoir Summit, Kelly's Half Way Inn, Tumble Inn, and Sandberg's Summit Hotel. North of the forest, the Ridge Route passed through Deadman's Curve before ending at Grapevine.
