Mount Diablo State Park stands as a jewel of the Bay Area, offering an incredible array of recreational activities, breathtaking natural beauty and hidden wonders. The park is a hotspot for hiking, horseback riding, road cycling, mountain biking, hang gliding, rock climbing, nature viewing, and more.
At the park’s summit sits a visitor’s center, which was built in the late 1930’s and serves as an enriching hub for visitors. From here, visitors can take in the remarkable 360-degree views that extend across the entire Bay Area. On clear days, visitors can see as far as the Golden Gate Bridge, Mount Shashta, and Yosemite.
A park-within-a-park, Rock City boasts distinctive sandstone formations, caves, fossiliferous rocks, and crevices that invite exploration and rock climbing, making it an adventurous delight for visitors of all ages.
The park also boasts a spectacular display of wildflowers in the spring, with over 400 species of flowering plants including California poppies, lupines, California goldfields, shooting stars, and many more. View our Wildflower Guide when planning your springtime stay.
As autumn sets in, an unusual natural event captivates those who are lucky enough to witness it—tarantula mating season. During this period, the park becomes a fascinating witness to the courtship rituals of these intriguing creatures, offering an extraordinary experience for nature enthusiasts.
