Facilities - Activities
Many visitors to Mount Diablo head straight for the summit to enjoy the famous view. Summer days are sometimes hazy, and the best viewing is often on the day after a winter storm. Then, you can look to the west, beyond the Golden Gate Bridge, to the Farallon Islands; southeast to the James Lick Observatory on Mount Hamilton at 4,213 feet elevation; south to Mount Loma Prieta in the Santa Cruz Mountains at 3,791 feet elevation, north to Mount Saint Helena in the Coast Range at 4,344 feet elevation, and still farther north to Mount Lassen in the Cascades at 10,466 feet. North and east of Mount Diablo the San Joaquin and Sacramento Rivers meet to form the twisting waterways of the Delta. To the east beyond Califomia's great central valley, the crest of the Sierra Nevada seems to float in space.

The Visitor Center highlights the cultural and natural history of Mt. Diablo State Park. Visit the Mitchell Canyon Information Center on the north side of the mountain. Exhibits
Impressive exhibits chronicle the history of the mountain and capture its majesty. A rock wall with instructional video examines the geological forces which created the mountain. Panels describe the native American history of the region. A diorama, complete with native sounds, offers an overview of the park's ecosystems. A model of the mountain acquaints visitors with important park locations. Splendid photographs enhance the visitor's experience.
