About this challenge

The San Francisco Bay Area Six-Pack of Peaks Challenge has eight peaks and asks you to log any six. Elevations run from Mission Peak at 2,517 ft to Mount Saint Helena at 4,341 ft, the tallest on the list and one of the few Bay Area mountains that gets snow in winter. Distance matters more than height here: suggested routes range from 6.2 miles for Mission Peak to 20.2 miles and about 4,500 ft of gain for Rose Peak.

Set your own pace: six days, six weeks or six months. A good plan is to start with Mount Umunhum and work up to the longer climbs, such as Mount Diablo (13.2 miles), Mount Tamalpais (15 miles) and Rose Peak, which crosses the Ohlone Wilderness. Mount Sizer is steep and includes an optional side trip to Jackass Peak. Mount Diablo State Park is open 8 a.m. to sunset, so plan a start that gets you back before closing.
