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.

The 2020 challenge has an expanded list of 18 peaks, including six in San Diego County. This overview page gives you links to detailed trail guides for each. The 2020 challenge begins on January 1, 2020.


I hiked Mount 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

I hiked 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

I hiked Mount Baldy

MOUNT SAN ANTONIO (MT BALDY) - Elevation 10,064' (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

I hiked 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

I hiked 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

I hiked San Gorgonio

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. 

Original Six-Pack route: Vivian Creek Trail to San Gorgonio


I hiked Ontario Peak

ONTARIO PEAK - Elevation 8,696' (2,651m)

Just north of Cucamonga Peak, this 8,696' summit is reached via popular Icehouse Canyon near Baldy Village. With a little extra effort, you can also bag nearby Bighorn Peak, too!

I hiked Mount Baden-Powell

MOUNT BADEN-POWELL - Elevation 9,406' (2,867m)

One of the highest peaks in the San Gabriel Mountains, Mount Baden-Powell climbs nearly 3,000 feet to commanding 360-degree views and a trip on the Pacific Crest Trail.

Trail Guides

I hiked Sitton Peak

SITTON PEAK - Elevation 3,273' (998m)

At an elevation of 3,273 feet is the lowest peak of the dozen, but conveniently close for Orange, Riverside and San Diego County residents. It's roughly 10 miles with over 2,100 feet of vertical gain to the summit.

Trail Guides

I hiked Sawmill Mountain

SAWMILL MOUNTAIN - Elevation 8,819' (2688m)

The highest point in Kern County at 8,819 feet, Sawmill Mountain is also part of the 3-2-1 Challenge (since you're there).

Trail Guides

I hiked Strawberry Peak

STRAWBERRY PEAK - Elevation 6,164' (1,879m)

The highest peak in the front range of the San Gabriel Mountains, and includes a steep ridgeline scramble to the summit. The 6,164′ summit rewards your scrambling skills with some sweet summit views.

Trail Guides

I hiked Santiago Peak

SANTIAGO PEAK - Elevation 5,689' (1,734m)

Hiking "Saddleback" from either the Maple Springs or Cadillac trailheads (both open) take you to the highest point in Orange County.


Note that for 2021, these are now part of the San Diego Six-Pack of Peaks Challenge.

I hiked Volcan Mountain

VOLCAN MOUNTAIN - Elevation 5,353' (1632 m)

This 5,353' peak has views of a transitioning landscape, with views that extend to the Pacific Ocean and even Catalina Island on a clear day, and to Anza-Borrego and the Salton Sea to the east. It was considered as a potential site for the observatory that was eventually built on Mount Palomar, and you can still see the remains of the outpost built during the siting study. It's also home to a USPS Air Mail signal tower that dates back to the 1920's when such towers guided pilots across the country at night.

Trail Guides

I hiked Cuyamaca Mountain

CUYAMACA PEAK - Elevation 6,512' (1,985m)

San Diego's second highest peak, with views that on a clear day can stretch from Mexico to the Coronado Islands.

Note that the Cuyamaca Fire Road to the summit is currently closed until later this year. Scott Turner has a couple of alternate routes that remain open and get you close to the summit (link below). If you hike one of the open routes to the point where it meets the closure area, that will count as a summit. If you really want to get to the summit, obey all closures and wait until the summit has reopened.

Trail Guides

I hiked Mount Woodson

MOUNT WOODSON - Elevation 2,881' (878m)

Better known for the side-trip to "Potato Chip Rock", Mount Woodson is popular for a reason.

At 6,535' Hot Springs Mountain is the tallest in San Diego County, making it a must-hike peak for high-pointers. It's located on the Los Coyotes Reservation, which requires a $10 entrance fee.

HIGH POINT - Elevation 6,138' (1871m)

The highest point on Mount Palomar is 6,138' High Point, with a strenuous 13 mile hike to match.

EL CAJON MOUNTAIN - Elevation 3,648' (1112m)

At 3,648' El Cajon Mountain is not the tallest by far, but this 11 mile trek climbs 4,000 vertical feet, making it one of the toughest in San Diego.
