Located in the rolling foothills of the Penninsular Mountain Range of northern San Diego County, Bonsall is an unincorporated area located about 40 miles north of downtown San Diego. Bonsall’s neighbors are Fallbrook to the north, Oceanside to the west, Valley Center to the east, and Vista to the south. Bonsall is characterized by golf courses and equestrian facilities. There is a relatively low density of residential real estate due to the area’s hill-and-valley topography. There are many lots for sale to build new homes, as well as equestrian properties.
