Orestimba is a local Indian word meaning "meeting place." Nearby are the famous Indian rocks and sycamore grove where mission padres met with the local Indian tribes. The place was visited by Lt. Moraga and Fr. Viader on October 25, 1810. It later became a favorite watering place for travelers along El Camino Viejo, "the Old Road," which traversed the west side of the valley from San Pedro to San Antonio.
