Mount Diablo State Park: Rock City to the Summit Professional Review and Guide

"Mount Diablo, the once sacred mountain of the Miwok Indians, continues to be sacred to today’s Bay Area hikers, mountain bikers, equestrians, and nature lovers. On this hike, you can watch rock climbers, scramble up a few boulders yourself, or search for ancient ocean fossils at Rock City; bird and butterfly watch and enjoy a hearty oak-laurel and gray pine forest on the Juniper Trail; identify wildflowers on the Summit Trail; barbecue at any of a number of picnic areas on the way up; learn about local history, geology, and wildlife at the Summit Museum; and take in breathtaking views of the Pacific Ocean and the snow-crested Sierra from the observatory tower at the 3,806-foot peak. Trails Surface: Single- and doubletrack dirt trails; the trail crosses over a paved road several times and includes a short walk over a paved parking lot."
