Many people say Yellowstone National Park is the best national park in America.
In 2021 it had a whopping 4.21 million visitors.
It was America’s first National Park.
Yellowstone is most famous for its thermal activity. Where you can see the famous “Old Faithful” erupt on a daily base, and hot springs that are far too hot for any humans to jump in. I have attached a video below for you to see Old Faithful erupt.
It is also home to the super volcano which scientists say could potentially impact the United States if it erupts.
If I could only see one park I think this would be the one.
