Diablo Country Club

Diablo Country Club sits in Diablo, a small unincorporated community in the Diablo Valley of Contra Costa County at the western base of Mount Diablo. Diablo is positioned in the San Ramon Valley at the foot of Mount Diablo State Park, where the mountain western grade descends toward the flat valley floor between Danville and Walnut Creek. The community is an enclave of large estate properties in the lower grades of Mount Diablo, surrounded by the protected lands of the state park above and the suburban communities of Danville and Alamo on the valley floor. The country club is the principal institution of this small residential enclave.
