About Pleasanton Ridge Regional Park

A 9,090-acre oak-covered ridge overlooking Pleasanton and the Livermore Valley. Source

This beautiful 9,090-acre parkland is on the oak-covered ridge overlooking Pleasanton and the Livermore Valley from the west. It is planned as the core of a Ridgelands Regional Park to be acquired over a period of many years. Parkland development has been intentionally limited to preserve the pastoral atmosphere.
