San Dieguito County Park is a 125-acre park located on the border between Del Mar and Solana Beach, California, two incorporated cities in northern San Diego County. It is locally popular for barbecues, weddings, and other group gatherings; there are no campsites. Other facilities include a basketball court, hiking trails, a gazebo, and a playground. One border of the park is the historical El Camino Real, which is also called King's Highway and sometimes California Mission Trail.
