Hidden Valley Open Space is a 1,000 acre grassland bowl at the northeast corner of the Windemere development in San Ramon.
Almost completely circled by exposed ridges, in just a few minutes' walk you can reach world class views of the urban Tri-Valley, Mount Diablo and lands to the east.
The center of Hidden Valley Open Space is reserved for wildlife such as the San Joaquin kit fox, tiger salamander, red-legged frog, and burrowing owl. The grassland, with its ground squirrel and rodent populations, and the ridges which force wind currents upward combine to attract lots of raptors: kites, kestrels, hawks, owls and golden eagles.
