You’d think the list of the tallest mountains in North America would be a simple "who’s who" of big rocks. But honestly? It's a mess of shifting borders, name changes, and geological ego. If you ask a random person in a bar what the highest peak is, they might say "Mount McKinley." They aren't technically wrong, but they're also about a decade behind the times.
That mountain has been Denali since 2015.
It’s not just about height, either. We’re talking about massive chunks of granite and ice that literally create their own weather systems. These peaks are so big they make the Rockies in Colorado look like rolling hills. Most of the real giants aren't even in the lower 48 states. If you want to see the true "roof" of the continent, you've basically got to head to the subarctic or the volcanic belts of Mexico.
The undisputed king: Denali
Denali is the big one. Standing at 20,310 feet, it’s the tallest mountain in North America by a long shot. It’s located right in the heart of the Alaska Range. What’s wild about Denali isn't just the final number on the altimeter; it's the vertical rise.

Everest is taller, sure. But Everest sits on the Tibetan Plateau, which is already 14,000 feet high. Denali rises from a base that's only about 2,000 feet above sea level. That means you’re looking at 18,000 feet of pure mountain right in your face. It’s a staggering sight that honestly doesn't feel real the first time you see it from a bush plane.
The weather there is brutal. We're talking -40 degrees in the summer. It’s a magnet for storms coming off the Gulf of Alaska. Because of its latitude (63 degrees north), the air is thinner than it would be at the equator. This makes it feel much higher than 20,000 feet. Climbers often say it’s a more "honest" mountain than the ones in the Himalayas because there's no army of porters to carry your gear. You haul your own sled. You dig your own snow cave. It’s a grind.
Canada’s massive secret: Mount Logan
Right behind Denali is Mount Logan in the Yukon. It hits 19,551 feet.
If Denali is the king, Logan is the fortress. It has the largest base circumference of any non-volcanic mountain on Earth. It’s not just a peak; it’s a massive plateau with eleven different summits over 16,000 feet. It is so heavy and so large that it actually affects the Earth's crust beneath it.
Funny thing about Logan—it’s still growing. Tectonic plates are shoving it upward even as you read this. It’s located in Kluane National Park, which is one of the most remote places on the planet. Most people will never see it in person because there are no roads. You fly in, or you don't go.
The volcanoes you didn't expect
Most people forget that Mexico has some of the tallest mountains in North America. These aren't just jagged granite peaks; they’re massive stratovolcanoes.
Pico de Orizaba (also called Citlaltépetl) is the third highest at 18,491 feet. It sits on the border of Puebla and Veracruz. Because it’s so close to the ocean, you can actually see the Gulf of Mexico from the summit on a clear day. Imagine standing in snow and looking at the tropical coast. It’s a weird contrast.
Then you’ve got Popocatépetl at 17,802 feet. This one is a bit of a problem child. It’s highly active. It regularly spits out ash and steam, which means climbers often can't go near it. It towers over Mexico City, a constant reminder that the Earth is very much alive down there.
Ranking the giants (The Top 10)
If we’re looking at the hard data, the list is heavily skewed toward Alaska and the Yukon. It’s almost unfair.
- Denali (Alaska, USA) – 20,310 ft
- Mount Logan (Yukon, Canada) – 19,551 ft
- Pico de Orizaba (Puebla/Veracruz, Mexico) – 18,491 ft
- Mount Saint Elias (Alaska/Yukon, USA/Canada) – 18,008 ft
- Popocatépetl (Mexico) – 17,749 ft
- Mount Foraker (Alaska, USA) – 17,400 ft
- Mount Lucania (Yukon, Canada) – 17,257 ft
- Iztaccíhuatl (Mexico) – 17,159 ft
- King Peak (Yukon, Canada) – 16,972 ft
- Mount Bona (Alaska, USA) – 16,550 ft
You might notice something missing. Where’s the Grand Teton? Where’s Mount Whitney?
Whitney is the tallest in the "lower 48" at 14,505 feet. In the grand scheme of North America, it doesn't even break the top 20. It’s sort of a reality check for hikers in California or Colorado. You might be at the top of your world, but you're still 6,000 feet below the summit of Denali.
Why Mount Saint Elias is the scariest
Mount Saint Elias is number four on the list, but ask any elite climber and they’ll tell you it’s the most intimidating. It sits right on the border of Alaska and Canada. The mountain rises directly from Icy Bay.
Think about that. You go from sea level to 18,000 feet in about 10 miles.
It is a wall of ice. Because it’s so close to the water, it catches every bit of moisture the Pacific throws at it. It’s perpetually covered in clouds and hammered by storms. It wasn't even summited until 1897 by the Duke of the Abruzzi, and it remains one of the least-climbed major peaks on the continent. It’s beautiful in a way that makes you feel very, very small.
The "Sultana" and the neighbor problem
Mount Foraker (17,400 ft) is often called "Denali's Wife" by the local Indigenous people (the Dena'ina call it Sultana). It’s right next to Denali. In any other part of the world, Foraker would be a legendary, world-famous peak. But because it sits in the shadow of the tallest mountain in North America, it gets ignored.
It’s actually a harder climb than Denali. The ridges are sharper, and the routes are more technical. But since it isn't "The Tallest," the crowds stay away. That’s the story for a lot of these peaks—they are giants that nobody talks about because they aren't number one.
Misconceptions about the "Seven Summits"
A lot of people think the tallest mountains in North America are just the ones they’ve heard of in the news. There's a big focus on the "Seven Summits" (the highest on each continent), which puts all the spotlight on Denali.

But geology doesn't care about our lists.
The Saint Elias Mountains, which straddle the US and Canada, are actually the highest coastal mountain range on Earth. The concentration of massive peaks there is higher than anywhere else on the continent. If you want to see where the real action is, don't just look at a map of the US. Look at the border where the Pacific plate is grinding into the North American plate. That's the engine room.
Practical advice for seeing them
You don't have to be an elite mountaineer with $20,000 worth of gear to experience these places.
- For Denali: Fly into Anchorage and drive to Talkeetna. Take a "flightseeing" tour. Most pilots will actually land you on a glacier on the slopes of the mountain. It’s the easiest way to feel the scale without losing a toe to frostbite.
- For the Mexican Volcanoes: You can hike the lower slopes of Iztaccíhuatl fairly easily. It offers the best views of the active "Popo" without the danger of being on an erupting vent.
- For Mount Whitney: If you want to stand on the tallest point in the contiguous US, you need a permit. They are hard to get. People apply months in advance for the lottery. If you get one, it's a long, 22-mile round-trip hike, but it's "just" a walk—no technical climbing required.
What to do next
If you're actually planning to visit or climb, your first move should be checking the National Park Service sites for Denali or Wrangell-St. Elias. The weather windows are incredibly short—usually late May to early July.
Go look at the topographic maps of the Saint Elias Range. It’ll give you a much better sense of why these mountains are so much more than just numbers on a list. They are a different world entirely.
