San Dieguito County Park is a 125-acre park on the border between Del Mar and Solana Beach, California, two incorporated cities in northern San Diego County. The park is split into two sections, the upper park, which opened in 1965, and the lower park, which opened in 1977. 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.
