The NorCal Six-Pack of Peaks are a series of iconic Bay Area summit hikes.

Mount Umunhum
The peak was long off limits, but after a major cleanup operation removed almost all of an abandoned air force station, it was opened to the public in 2017.

Mount Saint Helena
This 4,341' peak is the tallest in the NorCal Six-Pack, and one of the few mountains in the Bay Area to actually receive snow in the winter.

Mount Tamalpais
This loop trail from Stinson Beach to the summit of Mt Tamalpais is a good choice for a summer hike since it can start in a cool morning fog along the coast. After hiking 8 miles and over 3000 vertical feet, you’ll find yourself on the summit of a mountain with a fire lookout tower.

Mount Diablo
This summit provides some of the best views in the Bay Area. On a clear day, you can see the Golden Gate Bridge and even the Farallon Islands beyond. To the east, the Sierra Nevada Range.

Mount Sizer
This hike steeply climbs and descends several ridges. Mount Sizer is the high point in the park along Blue Ridge. This loop is a clockwise loop from park headquarters that ascends “The Shortcut”– often cited as the steepest trail in the Bay Area.

Rose Peak
This hike through the Ohlone Wilderness travels rugged terrain and rolling green hills, with an optional detour to seasonal Murietta Falls.
