Donner Canyon Road Professional Reviews and Guides
"Mount Diablo is most often seen as dry grassland and scattered oaks on the south side, but on the less traveled north side of the mountain are shady, wooded canyons.
Because they’re protected from the sun most of the day, Donner, Back, and Mitchell Canyons have some of California’s best wildflower shows. The seasonal waterfalls in the upper reaches of Donner Canyon, especially in Wild Oat Canyon along Falls Trail, are spectacular."
