San Dimas

San Dimas is a residential town in Los Angeles County, California, located in the San Gabriel Valley. The streets run mostly straight and are lined with trees, with neighborhoods climbing gentle hills.

The arrival of the railroad in 1887 transformed the area from ranchland into a center for citrus fruit. Later the town developed into a residential community for commuters to the nearby metropolitan area.

The name comes from a Catholic saint, and the town maintains a friendly suburban character with single-family homes and local shops. Many residents use the nearby parks on weekends for walks and picnics.

The downtown area sits along Bonita Avenue, where shops and restaurants are located. Parking is usually easy to find, and most places are reachable by car.

A large water park sits within the town limits and draws many visitors from across the region during summer. The park takes advantage of the warm climate of Southern California for its attractions and pool facilities.
