11+ Acres in San Diego County’s Palomar Mountain Range | Off-Grid Living | Short-Term Rentals Permitted Set between Palomar Mountain and Lake Henshaw, this 11+ acre property offers a distinctly different way to experience San Diego: greater independence, privacy and the freedom of a more self-sufficient lifestyle. With a private well drawing Palomar Mountain spring water, solar-generated electricity and room to cultivate gardens and grow your own food, this is an opportunity to live beyond the reach of many everyday utility demands. Surrounded by Cleveland National Forest and the San Jose Valley watershed, the property features open meadows, sweeping views of the Lake Henshaw Basin and Hot Springs Mountain, and a sense of seclusion far removed from coastal life. This is one of the few places in San Diego where the seasons are genuinely part of the experience. Spring brings wildflowers and migrating birds. Summer days are moderated by elevation, autumn brings golden oak canopies and crisp mountain air, and winter can bring snow to the surrounding peaks. Nearby Palomar Mountain State Park and the Santa Ysabel Preserves offer miles of trails for hiking, cycling and horseback riding. The approximately 2,150 sq. ft. home is designed around its setting, with vaulted ceilings, post-and-beam architecture and a brick-lined fireplace with soapstone wood stove anchoring the main living space. Newly refinished red oak floors run throughout, while the updated kitchen features warm wood finishes and curated lighting. A wraparound patio opens to meadow and mountain views, creating an easy connection between the home and landscape. The primary suite includes a walk-in closet, reading nook and tranquil views. A second primary bedroom on the finished lower level has its own entrance, den and access to the one-car garage, offering flexibility for guests, extended stays or a separate workspace. A loft conversion offers potential for a third bedroom. Built for off-grid living, the property features a private well and temperature-controlled solar power house. In late 2025, approximately $45,000 was invested in new solar infrastructure, significantly upgrading the system and supporting long-term efficiency and reliability. The land is as much a part of the offering as the home. Coast Live Oak groves provide shade and habitat for local wildlife, while open meadows offer room for outdoor pursuits and potential gardens. Direct trail access leads into Love Valley, an established equestrian area with extensive riding trails, allowing you to ride directly from the property. Hiking and mountain biking are close by, and Lake Henshaw offers fishing and boating. Santa Ysabel and Julian provide nearby markets, bakeries and small-town gathering places, while Palomar Mountain’s general store and post office add to the area’s rural character. Valley Center and Escondido are approximately 50 minutes away, keeping North County amenities within reach. For buyers seeking acreage, privacy, four-season living, equestrian access and greater independence through off-grid living, this is a rare opportunity to embrace a more self-sufficient lifestyle in the mountains of San Diego County.
