Four Days Diablo

Trek across one of the largest wild landscapes in urban America

We’ll travel through paradise as we explore the wild and scenic wonders of one of the largest protected landscapes in urban America……up and over the steep shoulders of Mt. Diablo for more than thirty miles from Walnut Creek to near Brentwood in the Central Valley.  We’ll discover that saving Mt. Diablo has been a gift that keeps giving rewards to millions of us every day.
