Discover Diablo

Save Mount Diablo's mission is to preserve Mount Diablo's peaks, surrounding foothills, and watersheds through land acquisition and preservation strategies designed to protect the mountain's natural beauty, biological diversity, and historic and agricultural heritage; enhance our area's quality of life; and provide recreational opportunities consistent with protection of natural resources. Since Save Mount Diablo's founding in 1971, preserved open space has increased from less than 7,000 acres to over 120,000 acres in more than 50 parks.  

 Mount Diablo is still threatened by development. That could mean the loss of wildlife corridors, ecosystems, and recreational opportunities. Your support will preserve these natural lands forever to safeguard our quality of life, including the quality of our air, water, and vistas.



Discover Diablo is Save Mount Diablo’s new program of free guided public hikes.

Hosting two free public hikes on average per month (including many suitable for families, and some that showcase Save Mount Diablo properties), we seek to build awareness of the importance of land conservation in Contra Costa County and beyond. 

There is something for us all to discover in the nooks and crannies surrounding Mount Diablo; please join us on the trails to find your own individual inspiration!
