Its beauty is unrivalled with lush forests, hundreds of waterfalls, towering mountains, and mesmerizing canyons and lakes. It’s Yellowstone and nothing else on earth quite like it.
Yellowstone has just celebrated its 151st birthday, so we’re honoring this national treasure by sharing our top 9 reasons why it’s the greatest national park in the United States.

1. Yellowstone is the oldest national park in the USA
Trailblazing Yellowstone was the first national park in the US and inspired a global national parks movement – and that’s just one of the reasons why we love it. Established in 1872, Yellowstone became a national park almost 20 years before Wyoming, Montana and Idaho became official states. To this day, Yellowstone is one of the most beloved national parks, with over three million visitors each year.

2. Yellowstone is enormous
Yellowstone definitely takes the cake when it comes to size. Encompassing more than 2.2 million acres or nearly 3,500 square miles, Yellowstone is one of the biggest and greatest national parks in the US. It’s so big, it sprawls across three US states – Wyoming, Montana and Idaho (although its mostly located in Wyoming), and it’s bigger than Delaware and Rhode Island put together.

3. Yellowstone is a hot spring paradise
One of the most magical reasons why Yellowstone is the greatest national park is because it’s home to half of the world’s hydrothermal features, with more than 10,000 active hydrothermal features spread across it. Sitting on top of a dormant supervolcano, the park is dotted with hot springs, geysers, mudpots, fumaroles and travertine terraces. Over 60% of the world’s active geysers alone are found in Yellowstone, and you can see these natural hot springs shooting boiling water and steam into the air all over the park.


You’ll want to see the famous ones like the Lone Star Geyser, which spouts hot water 45 feet into the air. There’s also the iconic Old Faithful geyser, which is a must-see for all visitors to Yellowstone. This thousand-year-old geyser has been erupting water into the sky approximately every 90 minutes for centuries – which is how it got its name. Each incredible explosion lasts anywhere from 90 seconds to 5 minutes and catapults up to 8,400 gallons of boiling water up to 184 feet high.
While you’re waiting for the geyser eruptions, you can marvel at the technicolor hot springs and bubbling mud pots. The vibrant blue, green and orange colors you see are caused by trillions of microorganisms called thermophiles. Although they can’t be seen with the naked eye, they love the heat and come together to create the dazzling colors you can see.

4. Yellowstone is full of remarkable wildlife
You don’t get the title of the greatest national park without some amazing wildlife. America’s first national park has long protected some of the country’s most endangered and important species including grizzly bears, black bears, bison, moose, elk, wolves, bighorn sheep and mule deer. Home to an estimated 67 different mammals, 300 bird species, and 16 fish species, Yellowstone hosts the largest concentration of mammals in the lower 48 states.
In one day at Yellowstone, you could experience a handful of extraordinary wildlife sightings, from bear cubs tumbling after their mothers to bison roaming the great plains and bighorn sheep scrambling up the rugged mountains.
Bison are a particularly special sighting at Yellowstone, as the park is the only place in the US where bison have continuously lived since prehistoric times. If you’re lucky, you might get to experience a famous ‘bison jam’, where herds of bison congregate on the roads.

5. Yellowstone has hundreds of waterfalls
Forget what TLC said about not chasing waterfalls. Yellowstone is a waterfall wonderland, with hundreds of waterfalls across the park. While there are around 50 named waterfalls, there are hundreds of lesser-known falls you can reach by walking along the 900 miles of stunning hiking trails. If there’s any place to go chasing waterfalls, it’s Yellowstone!

7. Yellowstone has a rich cultural heritage
It’s not just about the nature and wildlife. Yellowstone has an incredible cultural heritage spanning thousands of years. There are almost 2,000 archaeological sites in the park, some with physical evidence showing people began living and moving through the area more than 11,000 years ago.
Once home to 27 Native American tribes, including the Shoshone, Bannock, Blackfeet, Crow, and Lakota peoples, Yellowstone continues to preserve the cultural traditions of these ancestral lands. There are several sites and exhibitions where you can get to know more about the history and culture of Yellowstone’s Native American tribes.

8. Yellowstone is a world-class act in conservation
Yellowstone is undoubtedly the greatest national park in the USA – and we need to keep it that way. The park works tirelessly to strengthen the ecosystem, protect wildlife, and honor the Indigenous guardians of the land. Native American campaigns advocate relocating bison to their lands, rather than culling and have helped protect grizzly bears. Hundreds of Native American leaders, led by the late Don Shoulderblade, a Cheyenne spiritual leader, created the Grizzly Treaty to prevent the removal of the grizzly bear from the US Endangered Species Act. As Yellowstone continues to enact world-class conservation programs, it’s on track to achieve green list status from
As it continues to demonstrate world-class conservation impacts, Yellowstone could likely achieve the International Union for Conservation of Nature’s (IUCN) green list status, a certification for successful nature conservation.
