The Tallest Peaks in Every State (and D.C.)

The U.S. is an expansive and diverse land, with everything from towering mountains and long coastlines to vast plains. Each of the 50 states, along with Washington, D.C., has its own highest point—from the majestic Denali in Alaska to the more modest summits of states like Florida and Delaware. These peaks serve not only as geographical landmarks but also as adventure destinations for climbers, hikers, and locals alike.

At 20,310 feet, Denali is the highest point in the U.S. and one of the Seven Summits—the tallest mountains on each continent. Climbing all seven is a prestigious achievement for serious mountaineers. On the other hand, Britton Hill in Florida, at just 345 feet, is the country's lowest high point. Many climbers take on the challenge of reaching all 50 high points (or 51 including D.C.)—a goal for the dedicated adventurer. These individuals are Highpointers, and their pursuit is as much about the exploration as it is about the summit itself.

Interestingly, many of the tallest peaks are found in the western U.S., where the Rocky Mountains and other rugged ranges shape the landscape. Mount Whitney in California, towering at 14,494 feet, is a prime example, standing as tall as nearly 10 stacked Empire State Buildings, showcasing the extraordinary elevations of the region.

You may be surprised to discover that the heights of mountains are not fixed—they can change over time due to geological factors like tectonic plate movements and weathering. Shifting tectonic plates can raise mountains, while erosion and weathering gradually wear them down. However, a study conducted by researchers in Germany, published in Nature in 2020, revealed that the height of mountains might be maintained by a balance between tectonic forces and the weight of the mountains themselves, with erosion playing a lesser role in height change.

Here’s a look at the highest points in each state, along with their approximate elevations.

Whether you’re an experienced climber aiming to conquer the tallest peaks or a curious traveler keen to visit the highest points across the nation, these mountains are an excellent starting point.
