The Ewing Preserve is a 24.6-acre parcel of protected land in the southeast section of Rancho Santa Fe between Linea del Cielo and Via del Alba. It features several miles of popular walking and equestrian trails, and a beautiful limestone and eucalyptus landscape. The preserve is home to a variety of native plants, including endangered species, such as the Scrub Oak, Del Mar Manzanita and Southern Maritime Chaparral, one of California's most endangered plants. The Association maintains and protects this land for use by its members.
