Nestled among the rolling hills of Norco Ridge Estates and the famous Hidden Valley Golf Club, this exceptional estate captures the essence of Southern California's coveted rural lifestyle while offering a backyard experience unlike any other. Set on approximately 0.66 acres, the property is surrounded by breathtaking rocky hillsides and horse trails, creating a setting that feels worlds away from the city. Designed for unforgettable gatherings, the backyard is a true showpiece. Massive real rock formations blend seamlessly into the natural hillside backdrop, creating a resort-inspired oasis centered on a spectacular multi-coloured Pebble-Tech pool and spa, featuring natural rock waterfalls and lounging areas. Entertain from the fully equipped outdoor kitchen featuring a Kegerator and seating for ten, gather around the custom outdoor fireplace with log storage and built-in stone seating, or enjoy the extensive real stone patios. Gated RV parking and a dramatic illuminated staircase leading to the PAKA zone further enhance this one-of-a-kind outdoor retreat. The ranch-inspired exterior welcomes guests with a covered front porch, Juliet balcony, and direct access to Norco's renowned horse trail system. Inside, the sprawling floor plan offers approximately 3,586 square feet with four bedrooms, a home office, a loft, and four wood-burning fireplaces. An intimate living room with a fireplace, currently used as a game room, opens onto a tranquil courtyard with a soothing fountain through French doors. The expansive kitchen boasts glass-accented cabinetry, stainless steel appliances, dual ovens, a warming drawer, an oversized preparation island, breakfast bar seating, and a sunny morning room. A Butler's pantry with a wine chiller provides additional convenience. Hand-distressed hardwood flooring and oversized baseboards enrich the main level, while the enormous family room offers walls of windows overlooking the backyard, a wood-burning fireplace, a built-in media alcove, surround-sound prewiring, and a direct connection to the kitchen. A downstairs bedroom with an en-suite bath is currently configured as a custom office with built-in cabinetry.
