OSUNA RANCH

Osuna Ranch is an historic 25-acre property purchased by RSF Association in 2006. Association members and their guests may enjoy miles of walking paths, expansive grass pastures, and equestrian boarding. At any given time, the stables house nearly 50 horses, many of them being show horses or jumpers that have trained at Hap Hansen Stables, a world premier horse training facility.

On the Osuna Ranch property is an old adobe home, believed to be one of the oldest existing structures in California. The original adobe was built in 1831 and is now listed on the National Register of Historic Places. The adobe was acquired by Juan Maria Osuna in 1836, the first alcalde (mayor) of San Diego, until it was sold to the Santa Fe Land Improvement company in 1906. Despite multiple remodels and changes in ownership, the Osuna name has survived.

Osuna Ranch hosts many community events throughout the year including Celebrate Osuna, Rancho Days, and the Fall Festival. An enclosed quarter-mile loop walking path was recently installed along Via de la Valle including a mulched walkway, irrigated trees and a dry creek bed. 

The Osuna Ranch is open to members and their guests daily from 7:00 am to 4:00 pm. Visitors are welcome to explore the ranch, walk the scenic pathways, and take a self-guided tour of the old adobe home to experience San Diego history. Members are asked to please avoid attempting to feeding or pet any boarding horses without owner permission.
