About this place
Rancho Cucamonga is a Southern California city in San Bernardino County, formed in 1977 from three distinct communities. Locals often shorten the name to "Rancho" and the areas of Cucamonga, Etiwanda, and Alta Loma retain their own identities. The city sits at the base of the San Gabriel Mountains, offering easy access to both mountain recreation and the broader Inland Empire.
The city blends suburban comfort with scenic backdrops and a growing selection of shopping and dining. It functions well as a relaxed base for exploring the region or enjoying a quieter pace away from central Los Angeles.
