Become a Friend of the Mountain

This is your mountain.

Whether you enjoy Mount Diablo when you are hiking, cycling, horseback riding, trail running, birding, painting, photographing, looking at it from your kitchen window, or taking in its breathtaking beauty at the end of that long drive home—this is your mountain.

Your financial support as a Friend of the Mountain allows Save Mount Diablo to preserve, defend, and restore the natural lands on and around the mountain for its wildlife and for you to enjoy.

You can also donate with confidence, knowing that you are contributing to an accredited, effective, fiscally responsible organization that’s having a real impact on the Diablo area. But don’t just take our word for it! We invite you to review our IRS Form 990s, audited financial report, and annual reports for the last five years.
