Explore the Black Diamond to Mt Diablo Trail Historic Corridor

May 5 @ 9:30 am - 2:00 pm

All Discover Diablo hikes are subject to, and will honor, all applicable COVID-19–related restrictions in place for our area.

Join founding Save Mount Diablo Board member and retired EBRPD General Manager Bob Doyle for an exploration of one of his favorite regional parks, where he worked as a park ranger.

We will explore the natural and cultural mining history of this large regional preserve. The route will take us past coal and sand mines on the Black Diamond to Mount Diablo Trail with views of Mount Diablo, Kreiger Peak, Morgan Territory, Deer Valley, Clayton, and the Pittsburg hills. There should be lots of wildflowers.

Be sure to bring plenty of water and a snack, and dress in layers. Sturdy shoes or hiking boots are recommended. Heavy rain cancels.

Restrooms available at parking lot.

Participants will also be required to accept our COVID-19 Protocol (available during registration).

This event is limited to 25 participants.
