Spring is a wonderful time to hike this loop on the lower slopes of Mount Diablo’s southwestern side. Our route, which includes portions of Stage Rd, Barbecue Terrace and Wall Pt Rd, takes us through big skies and open grasslands, woodland, and along a wide rocky vein with magnificent valley views.

Bring plenty of water and sun protection, since about half the hike lacks shade. 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.

***There will be a $6 park entrance fee (exact amount in cash required)

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