The drive from Livermore to Mount Diablo can be done on all back roads. I could easily have taken so much time getting there that it would have been too late to continue. The views from up top were very much worth it though, as you'll see. NOTE: The images of San Francisco and the Golden Gate Bridge are from between 30 to 40 miles away.
