You can hike the peaks from a number of challenging routes. You can hike them as day hikes or as part of an overnight backpacking trip. For 2018, we have introduced two alternate peaks: you can substitute Mount Baden-Powell for Mount Wilson; or Ontario Peak for Cucamonga Peak. 


Mt Wilson

MOUNT WILSON - Elevation 5,713' (1,741 m)

Mount Wilson can be hiked or backpacked year-round, and rarely gets dusted with snowfall. The summit is home to a cluster of telescopes that are still in use today, including the 100-year old, 100-inch Hooker telescope where Edwin Hubble discovered that the universe extended well beyond the Milky Way, and was in fact expanding.

Original Six-Pack route: Chantry Flats up Sturtevant Trail, down Winter Creek
Alternate peak: Mount Baden-Powell

Cucamonga Peak

CUCAMONGA PEAK - Elevation 8,859' (2,701m)

Cucamonga Peak towers above the Inland Empire, with epic views and an Instagram-friendly rock outcrop. It may or not get it's name from a Shoshonee Chief who sent his wayward daughter to live on the summit.

Original Six-Pack route: Icehouse Canyon to Cucamonga Peak
Alternate peak: Ontario Peak

Mount Baldy

MOUNT SAN ANTONIO (MT BALDY) - Elevation 10,069' (3,068m)

Better known as Mount Baldy thanks to it's tree-less, often snow-capped crown, this peak is the highest peak in the San Gabriel Mountains and the highest point in Los Angeles County.

Original Six-Pack route: Manker Flats ► Devil's Backbone ► Ski Hut Loop

San Bernardino Peak

SAN BERNARDINO PEAK - Elevation 10,649' (3,246m)

A challenger-favorite, San Bernardino Peak sits on a ridgeline that extends nearly to San Gorgonio, and in fact, is the western-most summit in the 9-Peaks Challenge

Original Six-Pack route: San Bernardino Trail from Angelus Oaks

Mount San Jacinto

MOUNT SAN JACINTO - Elevation 10,834' (3,302m)

John Muir described Mount San Jacinto like this, "The view from San Jacinto is the most sublime spectacle to be found anywhere on this earth!" Who are we to argue? San J towers above Palm Springs and provides an alpine environment right in SoCal. 

Original Six-Pack route: Marion Mountain Trail to San Jacinto

San Gorgonio Mountain

SAN GORGONIO MOUNTAIN - Elevation 11,503' (3,506m)

Old Greyback is the tallest mountain in the San Bernardino Mountains, and the highest point in Southern California. It's also the 7th most prominent mountain in the contiguous 48 states.
