Joseph D. Grant County Park

[1] Also known as Grant Ranch Park, this site is situated in the Diablo Range foothills of the eastern Santa Clara Valley.

Santa Clara County purchased approximately 9,553 acres (38.7 km2) of the land in 1975, and created this public park.

[3] This upward gradient leads to even higher peaks in the crest of the range and to Mount Hamilton itself at 4,209 feet (1,283 m).

The western slopes of Mount Hamilton drop into Smith Creek which forms the eastern boundary of the Park.

Some of the special status biota within Joseph D. Grant County Park are the burrowing owl and the Western pond turtle.
