High on the crest of Palomar Mountain, where towering trees frame views stretching from the Pacific to the Observatory, Round House Ranch is anything but ordinary. Set on 11.39 private acres, its distinctive twelve-sided home has been beautifully renovated from top to bottom, creating a turnkey mountain retreat with exceptional craftsmanship, usable land, and room to spread out. Inside, soaring old-growth timber beams frame an 18-foot vaulted great room with a wood-burning stove, where every window is a view. The beautifully finished kitchen features leathered granite counters with waterfall edge, custom maple cabinetry, and premium stainless appliances, flowing seamlessly to an expansive hardwood deck made for entertaining. Three bedrooms each offer an ensuite bath. A spacious downstairs family room, ideal as a media or homeschool room, and an indoor laundry and utility room add flexibility and potential. Step out from the lower level to an inviting patio, the perfect spot to watch the wildlife parade. Outside, broad areas of level, usable land unfold beneath mature cedars, firs, and oaks. The existing barn and stable facility adds versatility for animals, hobbies, a workshop, or storage, and the workshop could have potential to serve as an additional living option. RV hookups are waiting for you, with plenty of parking, garden beds, and room for chickens and other outdoor pursuits. A productive private well adds to the property's mountain homestead appeal. Take in distant Pacific and island views to the west, Palomar Observatory and San Jacinto to the north, spectacular dark skies, and four distinct seasons, all just 70 minutes from the coast. When evening falls, the sparkling city lights come on below, yet you're a world away from the stress of the city. Just over a mile from Palomar Mountain State Park, Round House Ranch offers a rare combination of turnkey living, privacy, usable acreage, and authentic mountain character.
