Tucson's Crown Jewel! A rare opportunity to own the highest home in the Tucson area with astonishing 270° vistas stretching 60 miles across the city and desert to the surrounding mountain ranges and beyond! Begin every morning with a brilliant sunrise emerging out of deep orange dawn glow. End every day with glorious sunsets over the Sonoran Desert, and behold the most dazzling sweep of city lights at night, with shining stars above. It's an unparalleled, constantly evolving, awe-inspiring display of color and luminosity you can experience from the comfort of your architect-designed, 4-bedroom, 5-bath home on 4 acres--smartly remodeled in 2024--with ultimate privacy, tranquility, and security behind three gates. This is the only home fully situated up on the crest of the Tucson Mountains, at almost 4000 ft elevation, a world away from urban bustle but only 20 minutes to downtown. The west side of the property borders the protected lands of Tucson Mountain Park, ensuring lasting peace and quiet with up-close views of rocky Tower Peak. The mountain ridge has its own pleasant micro-climate, 5-7° cooler than the city in summer with gentle warm desert evenings ideal for outdoor living and stargazing. On approach, you pass through two successive gated entry points, then drive up the private road lined on both sides with beautifully crafted stone walls. Arriving at the estate, you'll be surprised, delighted, and uplifted by the expansive scenery, especially when a quick walk around the home reveals that the southern and western views are just as stunning as the eastern spectacle. The elegant split-face-block and stone house is surrounded by spacious flagstone and brick patios featuring wrap-around glass fencing for maximal sightlines. Enjoy the solar-heated pool and large built-in spa that can hold up to 10 people comfortably, as well as an open-air gazebo with mesmerizing vistas for shaded entertaining. The property features more than 100 saguaro cacti, visiting hummingbirds, soaring ravens, and the moon so big and close it feels like you can touch it. The bright interior of the home features new LED recessed lighting throughout, all new appliances, and fresh flooring treatments (2024). You'll have a primary kitchen with additional kitchenette/wet bar, both of which open to a great room with wood-burning fireplace, cathedral ceilings, high clerestory windows, and a wall of glass framing stunning views of the Catalina Mountains and the city far below, which becomes a dazzling panorama of light at night. All 4 bedrooms have sliding-glass doors with patio or balcony access, creating a constant connection with the natural desert environment. The primary bedroom features a stone fireplace and elegant en suite bath with an additional black-marble fireplace and spa tub with city and mountain views. A second extra-large bedroom at the opposite end of the house features its own city-view balcony with glass railing and a panoramic 9-ft-wide picture window looking west far across the desert. The home has two independent HVAC systems (2023) for ample heating and cooling, augmented by mini-split HVAC units (2025) in the primary and west-facing bedrooms. The three-car garage has its own mini-split, toilet, utility sink, closet space, and refrigerator (2025). The gated entry features a new intercom system and security camera (2025). Building a home in this magnificent location would be virtually impossible today, given current regulations and the significant cost of infrastructure, grading, and stonework. The benefits of many years of craftsmanship, engineering, and ingenuity are now yours to savor. From this singular vantage point, many Tucson landmarks are in full view, including Mt. Lemmon (sometimes snow-capped in winter!), the Catalina Mountains, Saguaro National Park East, the University of Arizona, downtown Tucson, Golden Gate Mountain, and Saguaro National Park West, with Old Tucson and the Arizona-Sonora Desert Museum in the valley below. Farther west, you have a magnificent view of Kitt Peak and Baboquivari, the sacred birthplace of humanity in the Tohono O'odham tradition. This stellar property is so much more than a house--it's a precious opportunity to live at the scintillating intersection of desert, mountain, sun, and sky.
