California has the highest quantity of mountains in the lower 48 states – 6106 named mountains altogether. The formation of California’s mountain ranges is attributed to major tectonic activity, bur geographic features are considered undeveloped in geologic terms and mountains are continuing to form and grow today.

The state is generally divided into two sections: Northern California and Southern California. However, scientists often divide the state into eleven distinct geomorphic provinces: Klamath Mountains, Cascade Range, Modoc Plateau, Coast Ranges, Great Valley, Sierra Nevada, Basin Ranges, Mojave Desert, Transverse Ranges, Peninsular Ranges and Colorado Desert.

Mount Shasta

Each of these geomorphic provinces include a diverse set of mountain ranges, but some are more extraordinary than others. Cascade Range, Coast Ranges and the Sierra Nevada are the most popular in Northern California, while the Traverse Ranges and Peninsular Ranges are more popular in Southern California.

Cascade Range

Southern California’s Traverse Ranges – named for their east to west orientation - begin at the Southern end of California Coast Ranges and traverse 5 major counties: Santa Barbara, Ventura, Los Angeles, San Bernardino and Riverside. Notable peaks within the Traverse Ranges are: Mt. San Gorgonio, Anderson Peak, Mount San Antonio, Sugarloaf Mountain, Mount-Baden Powell, Cucamonga Peak, Telegraph Peak, Ontario Peak, and Frazier Mountain.

Mount San Antonio

The Cascade Range, in Northern California, actually extends from Lassen Peak (or Mount Lassen), located in Lassen National Park, all the way North into British Columbia. The most popular peaks in the California Cascade Range are Lassen Peak and Mt. Shasta, which is home to the highest peaks in the entire Cascade Range.

Mount Lassen

Located in the heart of California, you’ll find the largest peak in the contiguous United States, Mt. Whitney, in the Sierra Nevada Mountains. Other peaks in the Sierra Nevada range from 11,000 to 14,000 feet above sea level and are composed of mostly granite. The Sierra Nevada mountain range is home to three of California’s most awe-inspiring national parks - Yosemite National Park, Sequoia National Park and Kings Canyon National Park - and contains several of California’s 14-ers: Mount Whitney, Mount Williamson, North Palisade, Mount Sill, Mount Russell, Polemonium Peak, Split Mountain, Mount Langley, Mount Tyndall and Middle Palisade.

Mount Whitney

Major Trails and Hiking Areas

Northern California

Mt. Whitney is California’s most popular fourteener. The Mt. Whitney trail is a well-maintained, 11-mile out and back footpath that begins at 8,360 ft and continues to approx. 14,498 feet - a total elevation gain of 6, 137 ft. There are over a dozen routes to the summit, for varying levels of hikers. A permit is required.

Mount Whitney

Mt. Langley is the southernmost of all the California 14-ers and has an incredible vantage point of the Southern Sierras. Mt. Langley is considered to be a great starter climb for those interested in acclimating to fourteen thousand-foot peaks. The peak can be easily accessed via the Cottonwood Lakes Trail, a 19-mile trail, which sits at 10,000 ft.

Mount Langley

Thousand Island Lake Loop, is a 22-mile trek that overlaps with two of the most iconic thru-hikes in the states: The Pacific Crest Trail and John Muir Trail. However, you don’t need to travel the whole trail to experience some of the best wilderness in California. From the High Trail you can catch a glimpse of craggy summits Mt. Ritter, Banner Peak and the Minarets in as little as 3 miles. Continue on for 7.8 miles to experience an unobstructed view of the 12,945-foot Banner Peak.

Mount Ritter

Lassen Peak is a 6-mile round trip trek up to the 10,000-foot summit in Lassen National Park. It only requires 2,000 feet of elevation gain, because the trail starts at 8,000 feet. From the top you can see all the way to Mt. Shasta.

Mount Shasta

Southern California

Mount Baldy, also known as Mount San Antonio, is a Southern California icon located in the San Gabriel Mountains. An 11-mile out and back hike and 3,800 feet of elevation, will take you to two peaks: one at 10,064 feet and a sub-peak at 9,988 feet. The high attitude and easy access makes this a popular hike to train for other fourteeners, like Mt. Whitney.

Mount Baldy

San Gorgonio is a challenging 18.5 mile out and back hike that brings you to the highest peak in Southern California. San Gorgonio is the only mountain that can be seen from Mt. Whitney, 190 miles away. The San Gorgonio hike is a technical climb, so it’s recommended that you hike San Jacinto or Mt. Baldy, first.

San Jacinto Peak

Major Cities and Resorts

Several areas in California are popular tourist destinations, but these are the top three:

Los Angeles

Los Angeles is the second most populated city and metropolitan area in the United States. The city is located in a large basin surrounded by the Pacific Ocean and both the San Gabriel Mountains - home to Mt. San Antonio - and the Santa Monica Mountains. Los Angeles boasts over 75 miles of coastline and several accessible hiking trails.

In addition to being the entertainment capital of the world, Los Angeles is well known for its idyllic weather and Hollywood stardom. The city offers a variety of tourist attractions which include over 100 museums, Universal Studios, The Hollywood Walk of Fame, The Getty Center and Venice Beach.

Los Angeles

At the base of the Santa Monica Mountains, you’ll find the 1,600-foot-tall peak of Mt. Hollywood, where you’ll see the famed Hollywood sign and the Griffith Observatory. Los Angeles is known to be a cultural mecca and has hosted the Summer Olympics, twice. It comes as no surprise that more than 47 million people visit the city, annually.

San Diego

120 miles south of Los Angeles, San Diego is California’s second largest city and the eighth largest in the United States. With over 1.3 million residents, San Diego is known for its renowned Gaslamp District, Balboa Park, the San Diego Zoo, San Diego Zoo Safari Park, and 600-acre Anza-Borrego Desert State Park.

San Diego is often considered the “birthplace of California” and offers over 70 miles of pristine beaches along the Pacific Ocean. The city has approximately 200 deep canyons and hills separating its various mesas, which create idealistic pockets of natural, open space.

San Diego

San Diego’s large city limits include many natural preserves, including Torrey Pines State Reserve - a 2,000-acre coastal state park located in the community of La Jolla. Interestingly, it also has one of the highest counts of animal and plant species that appear on the endangered species list in the United States.

Adventurers will appreciate a variety of hiking trails sprawled throughout San Diego County like the famed Potato Chip Rock on Woodsen Mountain, Stonewall Peak in Cuyamaca Rancho State Park, Corte Madera Mountain and Cowles Mountain in Mission Trails Regional Park.

San Francisco

Located on a peninsula between the Pacific Ocean and San Francisco Bay, San Francisco is one of the most popular tourist destinations in California. The city offers breathtaking views of the San Francisco Bay, a drowned river valley that was submerged during the melting of the last glacial ice sheet, and the famed Golden Gate Bridge (which is actually red).

San Francisco is best known to be a city where contemporary art and culture merge to form a hilly, uniquely featured city surrounded by mountains and coast. Noteworthy San Francisco attractions include Alcatraz, a rocky island in San Francisco Bay that once served as a federal prison, Pier 39, Golden Gate Park, Lombard Street, and a variety of contemporary museums.
