166 Leafy Pass Perched within the prestigious guard-gated enclave of Alta Vista at Orchard Hills, this masterfully designed estate offers a rarely-found combination of 6 bedrooms and 6.5 bathrooms, with refined, livable interiors and thoughtful amenities throughout. A soaring grand entry and dramatic dual staircase lead to open-concept living anchored by a wide-open living area and a chef's dream kitchen featuring Wolf and Sub-Zero appliances, a generous center island, floor-to-ceiling custom cabinetry, and a fully equipped prep kitchen. The south-facing living areas, together with a dedicated entertaining room, a true hidden gem, take in mountain, orchard, Catalina, and sunset views, with distant ocean glimpses on clear days. A main-level suite, a private retreat for guests or extended family, completes the main level. Upstairs, the luxurious primary suite features a flex room, a spa-inspired bath with a soaking tub and oversized shower, and a huge walk-in closet, all presenting incredible views, joined by four additional en-suite bedrooms and a laundry room. A connected four-car garage and tremendous driveway give car lovers all the parking and display space they could wish for.
