Ever wondered which mountains in the U.S. touch the sky—but aren’t in Alaska?
The continental United States is home to some stunningly tall peaks that often go unnoticed. These mountains may not be as famous as Denali, but they still reach impressive heights. Climbers, hikers, and nature lovers from all over the world are still attracted to them.
In this article, we’ll take you through the 10 tallest mountains in the continental United States. You’ll learn where they are, how tall they stand, and what makes each one different.
The Top 10 Tallest Mountains in the United States
The continental United States includes the 48 neighboring states, apart from Alaska and Hawaii. While Alaska is home to the country’s absolute tallest peaks, the mainland has its impressive summits. Here’s a look at the top 10 tallest mountains in the United States (excluding Alaska), based on elevation above sea level.
Mount Whitney, California – 14,505 feet
Mount Whitney is the undisputed king of the Lower 48. Located in California’s Sierra Nevada range, it rises to 14,505 feet, making it the tallest mountain in the continental United States. It attracts hikers and climbers from all over the world, primarily through the popular Mount Whitney Trail. Although the trail is non-technical, it’s physically demanding, with high altitude and steep switchbacks. Permits are required, and the weather can be unpredictable. On clear days, the summit offers sweeping views of Sequoia National Park and beyond.
Mount Elbert, Colorado – 14,440 feet
Mount Elbert stands as the tallest point in Colorado and the entire Rocky Mountain range. Standing at an elevation of over 14,000 feet, it is still considered one of the gentlest climbs. There are numerous non-technical routes available. With beautiful scenery, it’s no wonder first-time “14er” climbers find it appealing.
Mount Massive, Colorado – 14,428 feet
Mount Massive earns its name from its long ridgeline and five separate summits over 14,000 feet. Located in the Sawatch Range near Mount Elbert, it is only 12 feet shorter but often less crowded. Its regular route, the East Slopes route, is considered a Class 2 trail, making it a good option for experienced hikers looking for something a little more remote. Mount Massive offers panoramic views and a sense of grandeur that lives up to its name. It sits third out of the top 10 tallest mountains in the United States.
Mount Harvard, Colorado – 14,421 feet
Named after Harvard University, Mount Harvard is part of the Collegiate Peaks Wilderness. Its long approach and moderate technical demands make it a favourite for multi-day backpacking trips. Hikers can pair it with nearby Mount Columbia for a challenging double summit. The remote setting and sweeping vistas over the Arkansas River Valley add to its appeal.
Mount Rainier, Washington – 14,417 feet
Mount Rainier (Tahoma) is the highest peak in the Pacific Northwest and one of the most iconic mountains in the United States. It’s an active stratovolcano covered in glaciers, located in Mount Rainier National Park. Climbing it requires technical mountaineering skills, ice axes, and rope travel. Due to its challenging nature, many climbers opt for guided groups. On a clear day, Rainier is visible from Seattle, and it serves as a training ground for mountaineers preparing for peaks like Everest.
Mount Williamson, California – 14,379 feet
Located just 6 miles from Mount Whitney, Mount Williamson is the second-highest mountain in California and the sixth-tallest mountain in the continental United States. Due to its remote location and challenging approach, it’s far less trafficked. The trail to the summit includes steep, rocky sections and often requires an overnight trip. However, the reward is solitude, dramatic granite scenery, and a truly wild backcountry experience.
Blanca Peak, Colorado – 14,351 feet
Being the fourth-highest point in the Rocky Mountain range, Blanca Peak holds cultural and spiritual significance for the Navajo people. It is also the most elevated of the ten “14ers” in the Sangre de Cristo Mountains. Climbing Blanca is physically demanding and involves scrambling over rocky terrain. Its position in southern Colorado offers a unique blend of desert and alpine landscapes, along with views that stretch for miles across the San Luis Valley.
La Plata Peak, Colorado – 14,343 feet
La Plata Peak, whose name means “silver” in Spanish, is another towering member of Colorado’s Sawatch Range. It’s one of the most scenic climbs on this list of the tallest mountains in the United States, especially in late summer when wildflowers blanket the lower slopes. The standard route is straightforward and popular among day hikers, although alternate routes can be more challenging. Its rich mining history adds an interesting cultural layer to the experience.
Uncompahgre Peak, Colorado – 14,321 feet
This is the highest point in the San Juan Mountains of southwestern Colorado. Uncompahgre has a unique, flat-topped summit that stands out from the surrounding jagged peaks. The hike is long but not overly technical, and the views from the top include dramatic canyons, alpine meadows, and distant mountain ranges. It’s often climbed in the summer months when trails are clear of snow.
Crestone Peak, Colorado – 14,300 feet
Crestone Peak is the seventh apex of the Sangre de Cristo Range. It’s known for its steep gullies and abrupt cliffs. This quality makes it one of the more technical ascents among the tallest mountains in the United States. Crestone is isolated and challenging. Only experienced mountain climbers can attempt to scale it. The easiest route requires excellent route-finding skills and considerable climbing experience. Old-timers say that the views and sense of achievement at the summit make it a worthy climb.
Why These Peaks Matter
Mountains are more than just high points—they shape ecosystems, attract tourism, and hold cultural value. Some of the tallest peaks in the continental United States are also sacred to Indigenous peoples or play a role in state identity. For outdoor lovers, they offer adventure, challenge, and unmatched beauty.
Where Are the Tallest Mountains in the Continental U.S. Located?
Most of the tallest mountains in the continental United States are in California and Colorado, with one notable exception in Washington State. These mountains are part of well-known ranges like the Sierra Nevada, the Rocky Mountains, the Sangre de Cristo Mountains, and the Cascade Range.
Best Time of Year to Visit These Mountains
The ideal climbing season is typically June to September, when trails are mostly clear of snow and the weather is milder. However, some areas may remain snow-covered or experience sudden storms even in the summer, so it’s always best to be prepared.
Planning Your Climb
Climbing any of the top 10 tallest mountains in the United States is an exciting challenge. But it requires good planning and preparation. Here are some key points to keep in mind before you walk the walk:
- Tickets/Permits
Popular mountains, such as Mount Whitney, require permits. This helps control crowds and protect the environment. You typically need to book these permits several months in advance. You can reserve them through a lottery or online. Even if a peak doesn’t need a license, you may need one for overnight camping in national forests or wilderness areas. Check the official rules for each mountain before your trip.
- Weather
Mountain weather is known for being inconsistent. Before your climb, check the weather forecast for both the trailhead and the summit. Watch for signs of lightning, high winds, or snowfall—even in the summer months. Carry proper clothing layers and be prepared to turn back if the weather becomes unsafe.
- Gear
The gear you’ll need depends on the mountain and the season. For non-technical hikes like Mount Elbert, basic hiking boots, trekking poles, and plenty of water may be enough. But for more advanced climbs like Mount Rainier or Crestone Peak, you may need specialised gear such as crampons, helmets, harnesses, and ropes. Always bring a map, compass, headlamp, and first-aid kit—cell service can be unreliable in remote areas.
- Physical Fitness
These mountains are high—and so is the effort needed to reach their summits. Climbing above 10,000 feet puts a strain on your body, especially if you’re not used to the altitude. It’s essential to train ahead of time by doing regular hikes and cardio workouts. Acclimatise properly by spending a day or two at a moderate altitude before your summit attempt. This helps lower the risk of altitude sickness. Altitude sickness can cause headaches, nausea, and fatigue.
In Closing
The tallest mountains in the continental United States have peculiar challenges. Ranging from panoramic views to rocky crags, each summit offers breathtaking views and a sense of accomplishment. Whether you choose America’s tallest or Africa’s most iconic, the climb will always leave you with unforgettable memories and a greater appreciation for the mountains.
