Southwest Slopes of Mount Diablo

April 16, 2022 @ 9:00 am - 1:00 pm

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

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. All participants must bring a mask. Hand sanitizer will be available at the hike.

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

This event is limited to 20 participants.

 Are dogs allowed on Discover Diablo hikes?

No. Some Discover Diablo hikes take place on land owned by other organizations (such as Mount Diablo State Park & East Bay Regional Park lands) and many of the trails on these properties have a strict no-dog policy. 

Are there ID or minimum age requirements to enter the event?

Anyone under the age of 18 will need to be accompanied by a parent or guardian. 


Do I have to bring my printed ticket to the event?

No. On the hike day, we will have a roster with your registration information on it. Please make sure to check in with the hike leader.

Can I update my registration information?

Yes. If you would like to change anything, please contact Denise Castro at dcastro@savemountdiablo.org
