Diablo: Historic Country Club & Mount Diablo

Diablo is an unincorporated Contra Costa County community near Danville and the foothills of Mount Diablo. Residential streets developed around the historic Diablo Country Club, while custom homes, larger parcels, mature trees, golf course land, and changing terrain shape much of the area.

📝 Introduction

Diablo does not have a conventional downtown or commercial center. Instead, the community is organized around Alameda Diablo, Clubhouse Road, Diablo Country Club, residential streets, and roads leading toward the Mount Diablo foothills. Larger parcels, mature landscaping, older residences, custom construction, and changing terrain distinguish Diablo from the more urban development found in nearby Danville.
