Mount Olympia Road Professional Reviews and Guides
"For a nice bonus, try to go to Mount Diablo the day after a storm, when the skies have just cleared up and the smog and haze have not yet returned—the view from the summit of the Sierra Crestline is something else. To the west, you see Golden Gate Bridge and the ocean; all around you, mountains, from the Santa Cruz area in the south to Mount Saint Helens to the north. This trail guide contains descriptions of the following trails: Mount Diablo Falls."
