Diablo State Park at the foot of Blackhawk Ridge, Diablo enjoys easily-accessible shopping in nearby Danville, Alamo, Blackhawk and Walnut Creek while “living graciously in the country.” Although small, Diablo is noted for its exclusivity and actually is the 36th richest town in the United States.
California State Parks – Mount Diablo
California State Park – Mount Diablo is one of the ecological treasures of the San Francisco Bay Area. Every season in the park has its special qualities. Discover for yourself the mountain’s beautiful wildflowers, its extensive trail system, fascinating wildlife and distinctive rock formations. View the stars from its lofty heights, bike ride to its 3,849 foot summit or explore the more remote trails by horseback. The park offers hiking, biking, horseback riding and camping.
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.
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.
The Center has displays about various aspects of the park, such as geology, wildlife, trails, and plant life. Interpretive materials about the Park, such as geology, wildlife, and plants, are for sale. There are also postcards, note cards, trail maps, and water for sale.
