Located in the foothills of the Penninsular Mountain Range in the unincorporated area of northern San Diego County, Bonsall encompasses 33 square miles and lies 40 miles north of downtown San Diego, bordered by Fallbrook to the north, Oceanside to the west, and Valley Center to the east. Characterized by a series of hills and valleys, this topography has resulted in a predominance of low density, estate type residential lots and agricultural land uses. Golf courses and equestrian facilities dominate the landscape, contributing to its rural character. Home to the famous San Luis Rey Downs Training Center for Thoroughbred racehorses and other important equestrian facilities, Bonsall remains a true horse lover's paradise. Agriculture, horticulture, and vineyards thrive in this Mediterranean-like climate. The people of Bonsall enjoy living the country life while having quick access to everything the cities around it provide. Served by the Bonsall Unified School District, it consists of three elementary schools, a middle school, and a high school for its approximately 4,400 residents.
