Welcome to Five Arches Ranch, an extraordinary 639.5 acre estate in the heart of Californias Central Coast, where wide open space, wine country living, and true ranch luxury come together. Spanning three legal parcels, this legacy property offers a rare combination of agricultural production, equestrian facilities, residential comfort, and exceptional privacy. At the center of the ranch sits a beautifully maintained 7,772 SF main residence (7BD/6.5BA), built in 2008 and positioned at the end of a gated, cypress tree lined private driveway. Designed to frame panoramic ridgeline and vineyard views, the home features large windows, an attached guest quarters with a kitchenette, two 2 car garages, a resort style 40' x 20' pool with automatic cover, a built in spa, an outdoor kitchen with a pizza oven, and 745 feet of glass fencing surrounding the main compound. The chefs kitchen is complete with high end Dacor stainless steel appliances, a breakfast nook, sprawling granite counters, a walk in pantry, and a climate controlled wine cellar. The living room and loft benefit from soaring ceilings, natural light through large arched windows, and tasteful tile floors. Five Arches Ranch is deeply rooted in equestrian tradition. The extensive horse facilities include an impressive 60' x 50' horse barn with 11 stalls, an attached trainers apartment, 800 linear feet of fenced turnout, and a 40 foot radius hot walker. Additional structures include a 925 SF hay barn, a 4,000 SF equipment shed with a fuel station, a ranch office, two ranch houses, and a historic 1935 barn, seven buildings in total supporting full ranch operations. Agricultural assets include 12 acres of producing olive trees, 23 acres of Syrah (1998), 10 acres of Cabernet Sauvignon (2017), and extensive irrigated ground (264.62 acres). Four high capacity wells support farming, equestrian use, and future expansion. The ranch also offers grazing land, a second elevated plateau ideal for a future home site, and nearly 2 miles of Highway 46 frontage for accessibility. A property of this scale, versatility, and beauty is exceptionally rare in Paso Robles wine country. Five Arches Ranch offers land, luxury, privacy, water, and income potential, all in one extraordinary package.
