Property Description

The Converse Ranch was purchased and built out in 1908 by U.S. Steel and banking heir Edmond C. Converse Jr., known as the Millionaire Cowboy. Originally a sprawling 6,000-acre cattle ranch, it's now a 174+ acre legacy estate that's accessed via a dramatic, mile long driveway along the beautiful Santa Clara River Preserve. The original main house and all the historic structures are enveloped by citrus and avocado groves and equestrian facilities.... all with a magnificent mountain backdrop. Just West of the Ranch the 1,000-acre preserve continues, ensuring this spectacular setting will remain for generations to come. Rarely in Southern California can one ride horseback amidst such varied terrain; along the river, meadows and mountains... At the heart of the ranch is the grand 6,635 sq ft. main home that has been carefully restored and updated while maintaining all its original detail and charm. The second owners, one a member of the Doheny family, built the spectacular 40,000-gallon stone swimming pool. The carriage house and three additional guest/staff residences have also undergone thoughtful renovations. Horse lovers will find unlimited potential to expand on the existing facilities that include pastures, arena, 1908 barn structure and a contemporary 5,000 sq. ft. steel barn. Split into two parcels, each with city water supplies. The Eastern parcel features Rose Cottage that overlooks the river valley and out to the Channel Islands. Lastly, but most incredibly, the ranch comes with pre-1914 riparian water rights. This allows owners to pump river water to irrigate all the agriculture on the ranch. A rare opportunity to acquire a property of such historic and natural beauty just 90 minutes from Los Angeles.
