Olivenhain is the part of Encinitas where time slows down, and Lone Jack Ranch is the kind of property The Caspersen Group – Expert Realtor in Encinitas, CA rarely sees come to market. This home for sale at 3485 Lone Jack Road in Encinitas, California (92024) is a 15-acre estate with a private lake, mature landscaping, and the rural privacy that Olivenhain is known for, all just eight miles from the Pacific. In the North County San Diego real estate market, a property like this is genuinely rare.
The Land: Fifteen Acres That Speak for Themselves
The land is the story here. Fifteen acres in a community where most buyers are hoping for two or three. A private lake on the property, mature trees, and the kind of topography that lets you walk the land and feel like you’re somewhere well outside the city, when in reality the coast is a short drive away. The property sits inside one of Southern California’s most productive subtropical growing zones (USDA 10a to 10b, Sunset 24), which means avocados, citrus, and even bananas grow happily here. If you’ve ever wanted a working grove, a serious garden, or just a landscape that matures into something spectacular over the years, this is the soil and climate for it.
Infrastructure Built for the Long Haul
The infrastructure backs up the ambition. A 485-foot well drilled in 2005 delivers 128 gallons per minute, regulated to a 20 GPM flow into a 5,000-gallon storage tank with in-home filtration. Septic was certified in April 2025. These are the details that tend to separate a property you can actually use from one that looks the part on paper, and Lone Jack Ranch has its systems dialed in.
Equestrian Ready
For the equestrian side, the property is set up the way you’d want it. Olivenhain zoning allows two horses per acre, which gives this parcel real capacity, and the home includes a riding arena on site. Beyond the gate, you have access to a 30-mile trail network and two of the area’s most well-known riding centers. Whether you keep one horse or several, the setup is here.
A Canvas for What You Want to Build
The house and grounds work as a canvas. Whether you want to live in what’s there, expand and renovate, or build something new on this kind of acreage, the property gives you options you just don’t get anywhere else this close to the coast. Olivenhain parcels this large almost never come to market, and when they do, they tend to stay in the family for generations.
Olivenhain: Community and Location
Olivenhain itself is the quiet neighbor of Encinitas and Rancho Santa Fe, tucked between them and holding on to its rural character. Eight miles to the ocean, but you’d never guess it from inside the property line. The home falls within the Encinitas Union School District and the San Dieguito Union High School District.
Life Around Lone Jack Ranch
Life in this part of Encinitas is what draws people in and keeps them here. Downtown Encinitas and the 101 corridor (Fish 101, Herb and Sea, Leucadia Pizzeria, Union Kitchen and Tap) are a short drive when you want the coast, and Rancho Santa Fe village sits just up the road for dinner at Mille Fleurs or Thyme in the Ranch. The Del Mar racetrack, Torrey Pines, and the Cedros Design District are all within easy reach, and the San Dieguito River Valley trails are essentially in your backyard for riding, hiking, or just a long walk at sunrise.
An Encinitas Luxury Estate Like No Other
Lone Jack Ranch is the kind of Encinitas property that doesn’t repeat itself. Fifteen acres, private lake, productive soil, dialed-in water and septic, equestrian ready, eight miles from the beach. This is a legacy property in the making, and we don’t say that lightly.
