Welcome to Circle K Ranch—an iconic 554±-acre estate nestled in the heart of the Santa Ynez Valley. Rich in history, scale, and opportunity, this multi-parcel ranch is a legacy asset with unmatched infrastructure and natural beauty. Formerly known as the Double Arch Ranch, it was the vision of McDonald's founders Ray and Joan Kroc, who used the property as a corporate retreat and innovation hub. Gerald Kessler, founder of Nature's Plus Vitamins, continued its legacy as a private think tank, preserving its architectural soul while expanding its residential, recreational, and agricultural capabilities.

The property spans rolling pastures, wooded canyons, and ridge-line trails with sweeping views of Happy Canyon, often referred to as the ''Montecito of wine country.''Anchoring the ranch is the renowned 17,000±-sq ft Main Lodge with 25 en-suite double-occupancy rooms, a commercial-grade kitchen, a 3,000±-sq ft great hall, and a 5,200±-sq ft conference centerideal for large-scale events, retreats, or wellness programming. Prominently perched above it all, the iconic 5,200±-sq ft Round House, offers sweeping 360° views, a resort-style pool, circular drive, and unforgettable architectural character.

Additional features include multiple guest residences, barns, equestrian infrastructure, a roundhouse estate with pool and circular driveway, a gymnasium, tennis courts, helicopter pad, library, internal road systems, and two lakes supported by a robust water portfolio including numerous wells and cisterns.

The Ag-II zoning qualifies the property under the Santa Barbara Ag Enterprise Ordinance (AEO), opening the door for farmstays, camping, glamping, and on-site food service uses. Whether reimagined as a corporate retreat, regenerative wellness center, or lifestyle family compound, Circle K Ranch stands ready for its next steward.

The ranch is also offered in two separate configurations: the Front Ranch (1750 Rambling Oaks, Santa Ynez CA - 204± acres) at 14,950,000 and the Back Ranch (1959 Rambling Oaks, Santa Ynez CA - 349± acres) at 9,950,000.
