The valley is between the
Oakland Hills on the west, and the
Diablo Range on the east. The western side of the valley is formed by
Las Trampas Ridge. The valley's population is around 150,000 people. The city of
San Ramon, town of
Danville, as well as the southern edge of
Walnut Creek and the northern end of
Dublin are located in the valley, as are the
census-designated places (CDPs) of
Alamo,
Blackhawk,
Camino Tassajara and
Diablo.
Interstate 680 serves as the primary transportation route for the area. The
Iron Horse Regional Trail also runs the length of the valley. ==See also==
