Warner's Ranch, Historic ranch in San Diego County, United States

Warner's Ranch is a 221-acre historic property with two adobe buildings from 1849 and 1857 that show early California construction methods and daily life. The structures reveal how settlers built homes to withstand the local climate and landscape.

Juan José Warner, a Connecticut-born trader naturalized as a Mexican citizen in 1844, received the Rancho San Jose del Valle grant and opened the only trading post between New Mexico and Los Angeles on the Gila River emigrant trail. In 1851, during the Garra Revolt, his ranch was attacked and some buildings burned. John G. Downey, a former California governor, became sole owner in 1880 and began eviction proceedings against the Cupeño in 1892; the U.S. Supreme Court ruled against the tribe in 1901, and they were moved to Pala on May 12, 1903.

The land was long inhabited by the Cupeño, who encountered Spanish missionaries and were drawn into the mission system, losing control of land they farmed. Many later worked on the ranch, and on May 12, 1903, the tribe was relocated to the Pala Indian Reservation.

The ranch house is open to the public on weekends from 12PM to 4PM and by appointment. The site lies 4 miles south of Warner Springs in San Diego County. The 221-acre property holds the restored 1849 adobe ranch house and the restored 1857 Carillo Adobe and barn.

The 1857 Carillo Adobe on the grounds served as the original Butterfield Stage Station and trading post. The property also holds the restored 1849 adobe ranch house, where evidence suggests travelers stayed. Both adobe buildings survive on the 221-acre site.
