Hidden behind private gates and spanning nearly 23 acres of extraordinary Southern California landscape, Alto Mar is a rare legacy estate where sophisticated coastal luxury meets the timeless romance of the American West. Encompassing two distinctive yet seamlessly connected private compounds, The Villa and The Ranch, this remarkable offering combines exceptional residences, resort-inspired amenities, established equestrian facilities, and expansive open land into one extraordinary world, just minutes from the coast. At the heart of The Villa stands an approximately 8,000-square-foot architectural residence, exquisitely reimagined in a $4 million renovation with interiors by designer Hayden Crosby. Soaring ceilings, exposed beams, white oak floors, exquisite marble, and bespoke finishes establish an atmosphere of understated sophistication. Designed around a magnificent central courtyard, the residence opens to a resort-style pool, outdoor entertaining areas, fire pits, and lush lawns. A theater, game room, wine room, and private office complement the four-bedroom main residence, while three additional residences, an open-air entertaining pavilion, sports field, and basketball court create an exceptional setting for gathering generations. Connected through a private gate, The Ranch introduces an entirely different yet beautifully complementary experience. Its approximately 3,100-square-foot, Montana-inspired residence blends refined Western character with modern luxury, framed by pastoral views and an inviting courtyard with a wood-burning stone fireplace. Established equestrian amenities include five horse stalls, a riding arena, tack room, training areas, and fenced grazing grounds. A secluded three-bedroom guest residence, beautifully transformed two-story entertaining barn with eight bunks, private gym and sauna, additional finished spaces, and extensive RV accommodations further enhance the property’s remarkable versatility. Together, The Villa and The Ranch offer an unparalleled setting for multigenerational living, grand-scale entertaining, equestrian pursuits, and the freedom to create a truly personal legacy. With nearly 23 acres of privacy, natural beauty, and possibility, Alto Mar represents an increasingly rare opportunity to own an estate of extraordinary scale and character in coastal Southern California. Two distinct worlds. One extraordinary estate. For additional details, a site map, or private showings, visit https://altomarestate.com/.
