Diablo is easy to miss. It is a small community on the road that climbs Mount Diablo’s south side, and it grew up around the Diablo Country Club more than a century ago. Around twelve hundred people live here.
Why people move here
- The mountain is the neighborhood. Mt. Diablo Scenic Boulevard runs from town straight up to the state park’s south gate.
- The country club at the center of it, dating to the 1910s, with a course laid into the original resort grounds.
- Very few homes and no through traffic. Streets here wind, dead-end, and stay narrow by design.
- Danville is five minutes down the hill for groceries, the Iron Horse Trail, and everything else.
What to know
Diablo is unincorporated Contra Costa County — county permitting, county roads, no city government. Schools are San Ramon Valley Unified, the same district that covers Danville and Alamo.
There are only a few hundred homes in the whole CDP. If Diablo specifically is what you are after, it is worth being set up to hear about a listing early rather than refreshing a portal.
