Mount Diablo Summit with Devil's Pulpit

Mount Diablo Summit with Devils Pulpit

Mount Diablo Summit at an elevation of 3,849 feet (1,173 meters)

Mount Diablo Summit is the highest point in the East Bay. On its top sits the historic summit building, which was constructed between 1939 and 1942 by the Civilian Conservation Corps. This castle-like building with its stone walls, octagonal beacon tower and observation deck houses the Summit Visitor Center—open year round, every day from 10 a.m. to 4 p.m. On a clear day, you can enjoy views of the Farallon Islands, the San Francisco Bay Area and Carquinez Strait as well as parts of the Central Valley and the Sierra Nevada. Several hundred feet below the summit building, the Devil's Pulpit dominates the southeast slope of Diablo's chaparral and open-forest landscape. This monolith consists of erosion-resistant Franciscan chert formed over 90 million years ago far out at sea. It contains microfossils such as radiolaria that once settled on the ocean floor and over time transformed into chert. The North Peak Trail leads hikers from Devil's Elbow around Devil's Pulpit to Prospector's Gap and then uphill into the rugged North Peak area.
