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

Have you gone to the Mt. Diablo Park website for camping information? We were there for the day and did not do any camping.

Hi, The park opens at 8.am and closes at sun down. "Park Hours Gates open 8:00am and close at sunset. Visitors should plan to be in their vehicles by sunset and headed out to avoid being locked in".
