You may be familiar with Naples, Florida, and Naples, Italy. But what about the unincorporated area of Naples in Southern California?

Spanning a whole mile of ocean frontage just northwest of Santa Barbara, the largely undeveloped 1,000-acre oceanfront property known as Naples Ranch offers the opportunity to create a unique vision—with some caveats. The vast coastal spread, currently used for cattle ranching, comprises more than 220 legal parcels, plus an 18-acre lake where you can go bass fishing.

On the market for a cool $70 million with Kerry Mormann at Berkshire Hathaway Home Services California Properties, Naples Ranch (also known as Santa Barbara Ranch) has a long, fascinating history. For thousands of years, the land was under the stewardship of the local Chumash tribe, but the Naples name comes not from them but from a planned city that was never actually built there: An 1888 subdivision map shows the rolling acreage crisscrossed with streets lined with about 500 individual lots. However, because of its relatively remote location, lack of infrastructure, and the economic realities of the time, the imagined city never came to fruition.

In the late 20th and early 21st centuries, some legal development rights were established across the property, but a number of factors have made it difficult to build. In particular, there’s strong resistance from the local community and environmental groups, who would like to use the land for conservation. The Gaviota Coast Conservancy, for example, hopes to prevent development and prioritize public access and regenerative agriculture, among other public goods.

Though building up the property into a compound with multiple residences could be a challenge, due to both land-use regulations and preservation efforts, it’s the perfect spot for nature lovers looking for room to roam in total privacy along one of California’s most beautiful stretches of coastline. If a conservation easement were created, it wouldn’t automatically open the land to the public, and cattle ranching could likely continue, but it would largely protect the land, which also has access to loads of freshwater and is primed for planting fruits and vegetables like lemons and avocados.

While Naples Ranch is a rare offering in both scope and location, there are other supersized properties with more infrastructure in place that have come up for sale recently, including a 380-acre Northern California ranch and an L.A.-area estate that sprawls over about 5,600 acres.
