The oldest of the three communities that merged to form Rancho Cucamonga in 1977, Etiwanda retains a neighbourhood of late-Victorian and Craftsman-era houses, mature eucalyptus and pepper-tree-lined streets, and a quiet main street that feels notably different from the surrounding suburb. Etiwanda Avenue between Base Line Road and Foothill Boulevard is the spine of the historic district.
The 1913 Etiwanda Depot (now a private event venue) is the most prominent landmark. Rows of Victorian-era homes, a few historic churches, and citrus grove remnants fill the residential blocks. The neighbourhood is on the National Register as a Historic District. A self-guided walking tour pamphlet is available from the Rancho Cucamonga Planning Department.
