Major Mountain Ranges in the U.S.

Sierra Nevada Mountain Range

Length: 400 miles
Elevation: 4,421 feet
Highest peak: Mount Whitney

Located almost entirely in California, the Sierra Nevada Mountain Range is known for its significance in the state’s Gold Rush era. The Sierra Nevada is also widely praised for being one of the prettiest mountain ranges in the U.S., with plenty of opportunities to adventure and explore.

Among this sprawling mountain’s most notable features are General Sherman, the largest tree in the world; Lake Tahoe, the largest alpine lake in North America; and Yosemite, a national park sculpted from hundreds of millions of year old granites. There are two other national parks—Sequoia and Kings Canyon National Parks—on this gorgeous eastern U.S. mountain range, as well as plenty of other spots for unique experiences, wildlife sightings, and stunning views. 

Cascade Range

Length: 700 miles
Elevation: 14,411
Highest peak: Mount Rainier

The Cascade Range passes through western North America, crossing parts of Canada, Oregon, and Washington, before making its way to California. With beautiful snow-capped mountains and volcanoes like Mount Saint Helens (which last erupted in 2008), this western U.S. mountain range is as striking as they come.

Rainier, Shasta, Adams, Hood, and other beacons allow for unlimited adventuring on this majestic mountain range in the U.S. If you’re escaping to the California portion of the Cascade Range, you’ll most likely be exploring the mysteriously beautiful Mount Shasta towering 14,179 feet above sea level. Rent a cabin there during the fall and winter months, go on scenic drives through the nearby towns, trek numerous hiking trails winding through, and ski at the top resorts—the possibilities are endless on this western U.S. mountain range.

Alaska Mountain Range

Length: 400 miles
Elevation: 20,343 feet
Highest peak: Denali

The snowy peaks of the Alaska Range make it out to be one of the mightiest mountains in the world. While this American mountain range averages 7,000 to 9,000 feet in length, its central section soars much, much higher into the sky. In fact, its tallest point, Denali, reaches a whopping 20,310 feet in elevation and marks the highest summit in North America, qualifying Alaska as the tallest mountain range in the U.S.

Saint Elias National Park and Preserve, Lake Clark National Park and Preserve, and Denali National Park and Preserve are all located within the Alaska Range and allow for some of the best mountaineering and climbing in the state. Your climbing adventures atop this mountain range in the U.S. will not only be accompanied by incredible views, but also sightings of caribou, sheep, moose, grizzlies, wolves, lynx, and more amazing Alaskan wildlife.

Peninsular Ranges

Length: 930 miles
Elevation: 10,834 feet
Highest peak: San Jacinto Peak

The Peninsular Ranges, also known as the Lower California Province, are a group of mountain ranges that extend from SoCal all the way to Baja California—it encompasses the Temescal, Santa Ana, San Jacinto, Perris Block, Laguna, and about 50 more mountains.

To enjoy an adventure on this major mountain range in the U.S., hike the 21-mile-long Cactus to Clouds Trail. Don’t feel like stretching your legs that much? The famous Palm Springs Aerial Tramway can take you there; all you have to do to reach the San Jacinto Peak after is hike 5.5 miles. After you wrap up your mountainous adventure, consider spending the weekend in beautiful Palm Springs—it’s even better during the fall season.

While the southern parts of the California Coast Range have a predominantly Mediterranean climate, the northern parts are significantly colder. Check out the northern side for a forested getaway, with groves of redwoods, Douglas fir, and knobcone pine, or head to the Central Valley for more dry temperatures and desert-like terrain.
