Mount Diablo State Park is part of the California Department of Parks and Recreation. It offers hiking, biking, and equestrian trails. Even though it isn’t a very high mountain, it is surrounded by valleys and low hills so that you can see parts of 40 of the 58 counties in California.
The outdoor recreation and spectacular views from the summit of Mount Diablo are the main reasons this is such a popular RV campground near Vallejo, California. You are close to all the necessities in town, but once you are in the park, you are in a beautiful natural habitat. The visitor’s center located at the summit was built with sandstone that contains marine fossils.
“Absolutely stunning views. A real pleasure to visit. I went with my young kids and that wasn’t a problem because you can drive to the summit. There are so many picnic areas and glorious views and abundant wildlife.” – Jennifer, Google Review
