*At the eastern fringe of the San Francisco Bay Region, Mount Diablo, elevation 3,849 feet, stands alone on the edge of California’s great Central Valley. At this point, the Coast Range consists only of low hills, none high enough to block the view from the upper slopes of the mountain. As a result, the view is spectacular.
*Mount Diablo is a popular place to view the truly stunning scenery of coastal and central California-a kaleidoscope of deep bays, agricultural plains, and rugged mountains. To appreciate the physical aspect and spirit of Mt Diablo, explore it on foot and come into close contact with the plants and wildlife, the unique geology, even traces of forgotten history. An excellent system of trails is available to the adventurous ad to those who simply seek moments of peace and solitude to revitalize their spirit.
This hike goes for a counter clockwise loop up from the Regency Gate Trailhead in Clayton to Mt Diablo’s North Peak. Begin this hike at the end of Mountaire Pkwy-descend the steep trail to the Regency Gate Trailhead.
