Welcome to Lone Jack Ranch - A Rare Opportunity in the Heart of Olivenhain. Set in a community where time seems to stand still, this remarkable 15-acre estate blends rural tranquility with upscale coastal living. Whether you're an equestrian, builder, or someone seeking space to create lifelong memories, 3485 Lone Jack Rd offers the perfect canvas for your vision. Just 8 miles from the Pacific Ocean, this property features a private lake, mature landscapes, equestrian amenities, and endless development potential-a rare combination of natural beauty, privacy, and possibility. Located within one of Southern California's most productive subtropical zones (USDA 10a-10b, Sunset 24), ideal for avocados, citrus, and even bananas. A 485-ft well drilled in 2005 delivers 128 GPM with a regulated flow of 20 GPM, feeding a 5,000-gallon storage tank and in-home filtration. Septic certified April 2025. Zoning allows two horses per acre; includes riding arena and access to a 30-mile trail network and two premier riding centers. Lone Jack Ranch-an Encinitas legacy in the making.
