Neighborhood Gallery

1842 Alameda Diablo

Diablo’s luxurious homes flank Mount Diablo, with a backdrop of miles of open space. The community was developed in 1914 as a recreational area for residents of SF, Oakland and Piedmont.  Many homes and a club were built for vacationers.  The oak tree lined streets, community lake and golf course brought families here to enjoy.  Some of the original homes from the 1920's stil remain. Today there are almost 400 homes and a busy country club.  Nearby Mount Diablo State Park offers miles of hiking trails, bicycling, and campsites. On a clear day, you can drive to the top with a picnic lunch and enjoy views of the Sierra Nevada Mountains to the east and the Golden Gate Bridge and the Farallon Islands to the west.
