Cajon Pass, Road and rail mountain pass in San Bernardino County, United States.
Cajon Pass spans between the San Bernardino Mountains and San Gabriel Mountains, rising to an elevation of 3,777 feet in Southern California.
The first railroad through Cajon Pass was constructed in the 1880s by California Southern Railroad, connecting Barstow with San Diego through steep terrain.
Native Americans established early transportation routes through the pass, followed by Spanish explorers who named it Cajon, meaning box in their language.
Interstate 15 and two major railway lines traverse the pass, creating a vital transportation corridor between Los Angeles and the High Desert region.
The Pacific Crest Trail crosses through the pass where hikers encounter a McDonald's restaurant, making it an unexpected stop on their wilderness journey.
