I come from a part of the USA where the highest thing is a river levee so maybe I am just easily impressed. But the day I drove up to the summit, the air was clear and chilled. The view was stunning. I could see...More

We drove up from the south gate and left through the north gate. There's a self-pay ranger station partway up the paved road ($9 for seniors). You'll average about 15 miles per hour as you wind up to the summit, but it's worth it for...More

We drove to the top of the mountain but I saw quite a few spots for picnic and camping. The drive is a bit tough. You really need to be confident with your driving skill.

Drive to the top for a great view. Long winding road with blind curves and lots of bikes. Be careful and plan extra time. It takes a while to drive up because of the hair pin turns and bikes and pedestrians.

Gotta see rock city. The weather-carved sandstone structures are fun to climb on and in! Also - drive to (or walk to) the peak for unsurpassed views

We made the trip out to Mount Diablo because we were told it offered some spectacular views from its 3900 foot summit. It was a picturesque drive that was only challenged by the numerous bicyclists (we were there on a Sunday afternoon). From what we...More

Our second time to Mt Diablo, always breathtaking. The drive/ride up the mountain has a lot of curves which seem to go on forever, but it's worth it. Make sure you check out the viewing platform.

The drive to the top is rewarded with views to the west of the SF/Golden Gate Bridge and the snow capped Sierras to the east

We just climbed the big stone boulders which i'm sure she would be able to do. We saw other kids her age doing them. Hope that helps.

I did go to the website and decided to try here for an answer. Since then spent one night at Juniper site no area to jump in water or fish but a very nice campground and not far to the peak. I will return for more.

If you want to go right up to the summit, you have to get out before 8:30 pm (sunset; from memory, in summer) since they close the gates to that part for the night. But there are camping sites at the lower reaches (which are... More
