Mary Bowerman Trail Loop Professional Reviews and Guides

"Encircling the top of the Bay Area’s highest peak, on a clear day views from the Mary BowermanTrail stretch west to the Pacific Ocean and the curve of the earth and east across the CentralValley to the distant peaks of the Sierra Nevada."

"On a clear day, panoramic views from the Mary Bowerman Trail stretch west across the coastal hills to the Pacific Ocean and the curve of the earth, and east across the Central Valley to the distant peaks of the Sierra Nevada. The summit of Mount Diablo is more than 3,800 feet above sea level, and more than a thousand feet higher than its nearest neighbor. So it should come as no surprise that the views from the top—especially on a clear day—are superlative. The Mary Bowerman Trail circumnavigates the summit, offering the same views you’ll find at the observation deck on the peak’s apex with the added benefit of a natural history lesson and a chance to stretch your legs after the long, adventurous drive to the trailhead. Begin the hike in the lower summit parking lot, which is about 0.1 mile downhill from the smaller visitor center parking area."
