13040 N HIDDEN VALLEY Road This is not a home listing. It is a private desert mountain retreat, 133 acres with a private mountain compound at the summit. Gated, off-grid capable, no HOA, no visible neighbors, and bordering preserve land. A long private paved drive climbs through open Sonoran Desert landscape before the gate opens and the home reveals itself: arched colonnades, a large covered outdoor living area, and a freeform pool with rock waterfall and fire pit, all perched at the mountain's edge with nothing behind it but open sky, layered mountain ranges, and city light views stretching nearly 50 miles across the valley. The single-story Spanish hacienda-style home was thoughtfully positioned to maximize privacy, sunrises and sunsets, panoramic mountain views and glowing city lights in every direction. The fully accessible layout offers no interior steps and includes approximately 5, 347 square feet, 4 bedrooms, 5 full bathrooms, 1 half bath, a great room, bonus room, 3-car garage. Infrastructure is already in place for long-term self-sufficiency and flexibility, including a private well, owned propane, owned solar panels, water distillation system, SRP electric, septic, and multi-zone HVAC systems. The property offers exceptional versatility as a private mountain compound, equestrian property, secluded hillside estate, wellness retreat, multigenerational compound, remote luxury retreat, collector property, or investment opportunity. After dark, the city lights spread across the entire horizon. The land is the asset. The estate is the reward.
