About The Park

The Foothills 1,060 acres are valued for their striking geologic formations, their sweeping panoramas of the San Francisco Bay Region and the rural quality of the adjacent rolling grasslands.

Park Features
Besides panoramic views of the mountain and its surroundings, Diablo Foothills' 1,060 acres contain interesting geologic features, beautiful wildflowers in season, and a variety of bird and animal life.
Vegetation varies from grassland and oak savannah on the hills to riparian and oak woodland in the valley. Pine Creek flows through Pine Canyon and is within the eastern portion of the Walnut Creek watershed, which drains 150 square miles of central Contra Costa County into San Francisco Bay.
Diverse habitat types support an equally diverse array of wildlife, including mule deer, bobcats, coyote, grey fox, long-tailed weasels, raccoons, gophers, rabbits and ground squirrels. Birds such as red-winged blackbirds, northern mockingbirds, scrub jay, California quail and brown towhees use the park for nesting and foraging habitat. Rock outcrops shelter garter and gopher snakes, western fence lizards, southern alligator lizards, tree frogs and California salamanders. The perennial pools of water in Pine Creek ensure the survival of green sunfish, mosquitofish and largemouth bass. Back to top
