Join the Challenge

The 5th Annual NorCal Six-Pack of Peaks Challenge™ is a self-paced hiking and trail running challenge up six iconic Bay Area mountains.

You choose whether you want to complete them in six days, six weeks, or take the entire year. Set the schedule that works best for you.

You can climb them in order as you build your strength and endurance, or mix it up. The choice is yours. Your registration will help support Big City Mountaineers, so you'll be doing good for others with each peak you climb

The Peaks of the NorCal Six-Pack of Peaks Challenge

2022 Mount Umunhum

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.

2022 Mount Saint Helena

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.

2022 Mount Diablo

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.

2022 Mount Tamalpais

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.

Six-Pack Route Details: Hiking Mount Tamalpais
Distance: 16 miles; Vertical +/- 3,200 feet
