I took a few photos of Mt. Diablo, which is located in the East Bay of the San Francisco Bay Area in Northern California. Here's a wiki of it:

I really need to visit and actually go on the mountain because it's a very beautiful place to go sightseeing while seeing/listening and experiencing nature at its finest. I've been on a it a few times, and each time, I just get so amazed. Truly, it is a remarkable location that you need to visit if you're around the area.
