$5 per vehicle park entrance fee.
Black Diamond Mines Regional Preserve
Antioch, Contra Costa County

Black Diamond Mines Regional Preserve was once home to California’s most important coal fields. Today, we’ll be mining (figuratively) wildflowers in this Bay Area botanical hotspot.

We’ll also see the historic Rose Hill Cemetery and the underground Greathouse Visitor Center. The natural landscape immediately to the east of this beautiful park is at high risk of development. Check out ourĀ At Risk Report.
