Earth carries the scars of ancient impacts and volcanic eruptions, and craters are among the most dramatic reminders of those events. Some of the largest craters span hundreds of miles, while others are younger and better preserved. Among them, Meteor Crater in Arizona stands out as one of the most visible and best preserved anywhere on Earth. Here is a look at the biggest craters in the world, how they compare, and why Meteor Crater deserves a place on every traveler’s list.
Meteor Crater: Arizona’s Iconic Impact Site
Located near Winslow, Arizona, Meteor Crater, also called Barringer Crater, was created about 50,000 years ago when a meteorite slammed into Earth at speeds exceeding 26,000 miles per hour. The result is a nearly one-mile-wide, 550-foot-deep depression with an unmistakable bowl shape. Because of its young age and desert location, the crater has avoided erosion and remains one of the most well-preserved impact craters on Earth.
Visitors can explore the rim, tour the Discovery Center, and see meteorite fragments, making it one of the few major craters in the world where you can actually experience the impact site up close. Its scientific importance is equally impressive: Apollo astronauts trained here before their missions to the Moon, and researchers continue to study the site to better understand planetary geology.

The Biggest Craters in the World
Chicxulub Crater, Mexico
The Chicxulub Crater is one of the largest known impact structures on Earth, stretching over 90 miles across. Formed 66 million years ago, this crater is linked to the asteroid impact that contributed to the extinction of the dinosaurs. Unlike Meteor Crater, Chicxulub is buried beneath the Yucatán Peninsula and cannot be seen at the surface, making it invisible to visitors.
Vredefort Crater, South Africa
The Vredefort Crater is the biggest confirmed impact structure on Earth, measuring more than 185 miles in diameter. It was formed over 2 billion years ago, and erosion has erased much of its original shape. What remains today is a ring of hills that outline its boundaries. While scientifically significant and recognized as a UNESCO World Heritage Site, it lacks the sharp definition of Meteor Crater.
Wolfe Creek Crater, Australia
In the remote deserts of Western Australia lies Wolfe Creek Crater, a half-mile-wide impact site that formed around 120,000 years ago. Although smaller than Meteor Crater, it is still a striking sight. However, its remote location and limited accessibility make it difficult for most visitors to experience.
Lonar Crater, India
Lonar Crater in Maharashtra, India, is about 1.2 miles wide and is unique because it formed in basalt rock. Thought to be roughly 50,000 years old, it now holds a saline lake that draws scientists and tourists alike. While similar in size to Meteor Crater, its water-filled basin offers a very different view.
What Makes Meteor Crater Unique
While other craters may be larger or older, Meteor Crater stands out for its preservation, accessibility, and visitor experience. Unlike Chicxulub or Vredefort, which are eroded or hidden, Meteor Crater’s dramatic shape is immediately visible and easy to explore. Its location near Route 66 and Flagstaff also makes it a convenient stop for road trippers.
Meteor Crater is also unique because of its scientific and educational role:
- Nearly one mile wide and 550 feet deep, one of the largest visible craters accessible to visitors.
- Formed by a nickel-iron meteorite about 50,000 years ago.
- Designated as a National Natural Landmark for its preservation and significance.
- Home to the largest recovered meteorite fragment, weighing over 1,400 pounds.
- Served as a NASA training ground for Apollo astronauts preparing for the Moon.
For travelers and science enthusiasts, it is more than just a geological wonder. It is a living classroom that bridges Earth’s history with space exploration.
Meteor Crater Belongs on Your Bucket List
The world’s biggest craters each tell part of Earth’s story, but few are as accessible and visually striking as Meteor Crater in Arizona. It may not be the largest, but it is one of the only major impact craters where you can see the full scale of an impact event and learn through interactive exhibits and guided tours. If you want to experience the power of cosmic history firsthand, visit Meteor Crater!
