Mount Diablo has a forbidding image to many, in part because of its name. While creeks may dry in summer, the reality is that there are always cool canyons, and even on hot days cool breezes cross upper elevations. On the north side of the mountain are three large, wooded canyons. Because they’re protected from the sun most of the day, Donner, Back and Mitchell Canyons have among California’s best wildflower shows. The waterfalls in the upper reaches of Donner Canyon are icing on the cake. 

In winter (rainy season) and throughout spring, the Falls Trail offers fine views of the mountains most spectacular attraction, several waterfalls up to 100 feet high. Spring also brings astounding displays of wildflowers, and the colorful rock formations are worth the trip at any time. The waterfalls dry up during summer and fall before the winter rains. the hike is not difficult, but some stream crossings are steep and slippery. In winter and early spring, roads at lower elevations may be muddy. *1
