Alaska is known for the records of America’s tallest mountains, like Denali, which is about 20,000 feet, which outdoor enthusiasts have never reached that far north. In the lower 48, many mountains are seen and are the homes of such peaks. From the rugged Rockies of Colorado to the glaciated giants of California and Washington, these peaks offer stunning beauty, challenging climbs, and rich natural history. Here’s a detailed look at the 10 tallest mountains in the contiguous U.S., ordered by elevation.

A brief overview of the 10 Tallest Mountains in the Contiguous U.S.
1. Mount Whitney, California – 14,505 ft
Topping the list, Mount Whitney is the tallest peak in the Lower 48. Nestled within California’s Sierra Nevada range, its summit soars to 14,505 feet. Sitting right on the edge of Sequoia National Park and the Inyo National Forest, Whitney is famous for its sharp granite cliffs and panoramic views that stretch all the way to Death Valley. The popular Mount Whitney Trail attracts hikers from all over, despite the elevation challenge.
2. Mount Elbert, Colorado – 14,440 ft
Mount Elbert takes the second spot, claiming the title of Colorado’s highest point. Located in the Sawatch Range, Elbert is surprisingly approachable despite its elevation. Its slopes are gradual, and the standard trail doesn’t require technical gear, making it one of the most commonly climbed fourteeners (mountains over 14,000 feet) in the country.
3. Mount Massive, Colorado – 14,428 ft
Just shy of Mount Elbert’s height, Mount Massive lives up to its name. With five separate summits topping 14,000 feet, it has more surface area above that threshold than any other peak in the contiguous U.S. Also located in the Sawatch Range, it’s a favourite among backpackers looking for a more extended ridgeline adventure.
4. Mount Harvard, Colorado – 14,420 ft
Mount Harvard, part of the Collegiate Peaks, ranks fourth. It’s named after Harvard University, whose students first surveyed the peak in 1869. With expansive basins, alpine meadows, and rugged granite faces, this remote giant offers peace and solitude to climbers who venture into its less-travelled trails.
5. Mount Rainier, Washington – 14,411 ft
A dramatic presence in Washington State, Mount Rainier dominates the skyline near Seattle and Tacoma. Rising 14,411 feet, this glacier-covered stratovolcano is the tallest in the Cascade Range. Its icy flanks and unpredictable weather make it one of the more technically challenging climbs on this list. It’s also an active volcano closely watched by geologists.
6. Mount Williamson, California – 14,379 ft
Not far from Mount Whitney, Mount Williamson stands tall as California’s second-highest mountain. It’s much harder to access, though—its remote location and steep terrain make for a demanding trek. Rising sharply above Owens Valley, its jagged cliffs and massive rock walls give climbers an unmatched wilderness experience.
7. Blanca Peak, Colorado – 14,351 ft
Sacred to the Navajo Nation, Blanca Peak is the highest in the Sangre de Cristo Mountains. This dramatic mountain rises steeply from the San Luis Valley and is surrounded by striking alpine lakes, glacial valleys, and rugged rock. The spiritual and geological importance of Blanca gives it a unique spot on this list.
8. La Plata Peak, Colorado – 14,336 ft
Named after the Spanish word for silver, La Plata Peak reflects Colorado's mining heritage. Located in the Sawatch Range near Twin Lakes, it’s known for its steep ridges and scenic surroundings. Though it’s not as frequently climbed as Elbert or Massive, the Northwest Ridge trail provides a challenging but rewarding alternative.
9. Uncompahgre Peak, Colorado – 14,321 ft
The tallest mountain in the San Juan Mountains, Uncompahgre Peak is easy to recognise due to its flat, broad summit. It’s of volcanic origin, which sets it apart visually from many of Colorado’s other granite-dominated peaks. A moderately difficult climb from the Nellie Creek Trailhead makes it popular among hikers looking for great views without technical obstacles.
10. Crestone Peak, Colorado – 14,300 ft
Last on the list but far from easy, Crestone Peak is one of the most rugged and remote fourteeners in the country. Tucked deep within the Sangre de Cristo Range, it demands strong scrambling skills and route-finding ability. The South Face route includes Class 3 climbing, making this a favourite for experienced mountaineers who prefer solitude and challenge.
Conclusion
While Alaska may hold the title for the tallest mountain in the United States with Denali, the contiguous 48 states are far from lacking in awe-inspiring summits. From California’s granite giants to the snow-capped volcanic peaks of Washington, and the towering Rockies of Colorado, each of these mountains has its own unique story to tell. Whether it’s the spiritual significance of Blanca Peak, the remote challenge of Mount Williamson, or the alpine beauty of Mount Rainier, these peaks are more than just elevation numbers — they represent the heart of America's wild, untamed landscapes. For hikers, climbers, and nature lovers alike, exploring these mountains means connecting with some of the most majestic and iconic terrains in North America.
