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 Lassen Peak 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 California's great central valley, the crest of the Sierra Nevada seems to float in space.
Summit Visitor - Open Daily 10am - 4pm
The Visitor Center is located in the historic stone building atop Mount Diablo's highest peak. The tower was constructed during the late 1930's of fossiliferous sandstone blocks quarried in the park. The Visitor Center highlights the cultural and natural history of the park. Visit the Mitchell Canyon Information Center on the north side of the mountain.
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. A diorama, complete with sound, offers an overview of the park's ecosystems, and its cultural history. A model of the mountain acquaints visitors with important park locations. Splendid artwork and photographs enhance the visitor's experience. A gift shop and audio-visual room are also located in the building.
