San Dimas

San Dimas is a city in the San Gabriel Valley of Los Angeles County, California, United States. San Dimas is a suburb of Los Angeles nestled along the foothills of the San Gabriel Mountains, about 28 miles east/northeast of Downtown Los Angeles and north of the Pacific Ocean. San Dimas runs along and southward from historic U.S. Route 66, another part of its development in the earlier 20th century.

The area was originally developed in 1837 with the Mexican land grant from Governor Juan Bautista Alvarado to Ygnacio Palomares and Ricardo Vejar for the Rancho San Jose, then in Alta California. It later became known as La Cienega Mud Springs, so named because of local mud springs that created a riparian marsh and healing place. It was the arrival of the Los Angeles and San Gabriel Valley Railroad in 1887, later purchased by Santa Fe Railroad, that La Cienega Mud Springs was first mapped. The resulting land boom resulted in the formation of the San Jose Ranch Company, which first laid out streets. Small businesses began to open soon thereafter, and the city took on a new name: San Dimas. Growth was rapid, and San Dimas soon became an agricultural community.

San Dimas incorporated as a city in 1960, and is now known for its small town and equestrian qualities.

San Dimas is home to Raging Waters theme park, one of the largest water parks in California. Pacific Railroad Museum – museum/library located in the former ATSF San Dimas Depot on Bonita Ave.
