Acalanes Ridge Open Space is a relatively small natural area which straddles the ridge between Lafayette and Walnut Creek. The short hikes within the 177 acres provides sweeping vistas of Mount Diablo, as well as hidden sylvan creekside settings, perfect for cooling off on a hot summer day. From the ridge line you can see Mount Diablo as well as the Carquinez Strait and the delta to the north.
