The peaks of the san Francisco bay area challenge

MOUNT UMUNHUM – Elevation 3,486′ (1,063 m)

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. The hike uses a purpose-built singletrack trail that switchbacks up to the summit.

Suggested Six-Pack Route Details: Hiking Mount Umunhum
Distance: 7.4 miles; Vertical +/- 1,150 ft.

MOUNT SAINT HELENA – Elevation 4,341′ (1,323 m)

This 4,341′ peak in the Mayacamas mountains is the tallest in the NorCal Six-Pack, and one of the few mountains in the Bay Area to actually receive snowfall in the winter.

Suggested Six-Pack Route Details: Hiking Mount Saint Helena
Distance: 10 miles; Vertical +/- 2,100 ft.

MOUNT DIABLO – Elevation 3,849′ (1,173 m)

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. There is a line-of-sight with the summit of Half Dome in Yosemite.

Suggested Six-Pack route: Hiking Mount Diablo via Mitchell Canyon Visitor Center
Distance: 13.2 miles; Vertical +/- 3,274 ft.

MOUNT TAMALPAIS – Elevation 2,572′ (784 m)

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.

The Steep Ravine Trail is temporary closed due to bridge repairs and maintenance. You can still use the Matt Davis Trail as an out-and-back to summit Mount Tamalpais.

Distance: 15 miles; Vertical +/- 3,200 feet

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. Includes an optional side trip to Jackass Peak.
