Some of the specific points of interest in the park include the Rock City area, which features unique sandstone formations and caves, and the Mitchell Canyon Visitor Center, which offers educational exhibits and guided tours. The park is also home to a variety of plants and animals, including rare species like the Mount Diablo fairy lantern and the Alameda whipsnake.

Interesting facts about Mount Diablo State Park include that it is named after the Diablo Range, which runs through the park, and that it was once a sacred site for indigenous tribes like the Miwok and Ohlone peoples.
