466 Camino Sur Set within the iconic Old Las Palmas neighborhood - long favored by Hollywood's elite and prized for its close proximity to downtown Palm Springs' restaurants, retailers, and entertainment - this ultra-private Hollywood Regency residence captures the essence of classic desert living on an estate-sized lot with magnificent mountain views. Originally designed by Robert Marx, son of Gummo Marx of the legendary Marx Brothers, this residence carries a subtle Hollywood lineage that reflects the glamour and creative spirit of its era. A formal entry framed by floor-to-ceiling glass introduces interiors filled with light and connection to the outdoors. The expansive living room, anchored by a gas fireplace, opens to the backyard through sliding glass doors flanked by floor to ceiling windows while an adjacent formal dining room and adjacent bar create a natural flow for gatherings. A separate family room offers additional living space, also oriented toward the lush, private grounds. The kitchen is thoughtfully positioned for both function and flow, offering a casual sitting area, generous storage, and a dedicated space with built-in wine refrigeration - ideal for both everyday living and entertaining support. The bedroom layout offers flexibility and separation. The Primary Suite opens to the backyard and features a spa-like bath and walk-in closet. Bedrooms Two and Three enjoy west-facing exposure with direct outdoor access and a shared bath, while Bedroom Four (currently styled as an entertainment suite) can easily adapt to a variety of uses and the plumbing is already in place to add an ensuite bath. Outside, mature landscaping surrounds the home, creating a private resort-like setting. The south-facing front yard captures stunning mountain views, while the backyard offers space to relax, entertain, and enjoy the quiet beauty of the desert. A rare opportunity to reimagine a classic Hollywood Regency residence in one of Palm Springs' most prestigious and desired neighborhoods.
