25770 E GRADE ROAD BACK ON MARKET, NO FAULT OF SELLER OR PROPERTY A rare opportunity to own more than 11 pristine acres in the San Diego mountains, this secluded artist’s retreat on the eastern slope of Palomar Mountain captures the essence of refined country living. Enveloped by the Cleveland National Forest and overlooking the serene San Jose Valley watershed, the 2, 150 sq. ft. off-grid residence offers unobstructed views of Lake Henshaw Basin and Hot Springs Mountain, the highest peak in San Diego County. A wraparound patio frames the surrounding meadows and changing light. Inside, newly refinished red oak floors and Post & Beam architecture define an open layout anchored by a majestic fireplace. The kitchen, updated with warm wood cabinetry and thoughtfully chosen fixtures, creates a natural gathering space for cooking and conversation. The primary suite includes a walk-in closet, a quiet reading alcove and mountain views. A second suite on the lower level features its own entrance, den, and access to the one-car garage, offering privacy for guests or multi-generational living. With a private well, temperature-controlled solar power house, and minimal battery maintenance, the home delivers complete off-grid independence. A potential third bedroom could be created through a loft conversion. Surrounded by Coast Live Oak groves and open sky, the property offers direct trail access to Love Valley with miles of paths for horseback riding and hiking. The setting is rich in wildlife, privacy, and stillness, yet only a short drive from Santa Ysabel, Julian, and the historic Palomar Mountain general store. From the front door, a scenic trail winds through the Cleveland National Forest to a sweeping overlook of Lake Henshaw and stands of ancient Engelmann Oaks. Located just 25 minutes from Pauma Valley and Valley Center, and 50 minutes from Escondido, the property offers an ideal balance of seclusion and accessibility—well-suited for those seeking a full-time mountain residence, a low-maintenance weekend retreat, or an income-producing investment with remarkably low utility overhead.
