Yellowstone Nationall Park
Spanning almost 3,500 square miles, this park is a trove of steep canyons, incredible mountains, gorgeous waterfalls, and fascinating geysers.
It is also populated with teeming wildlife, such as elk, grizzly bears, and buffalo.
On top of that, it is home to the rainbow-sheened Grand Prismatic Spring, which is deeper than 10 stories and the third largest spring on the planet.
Plus, despite its pull of over 4 million tourists on an annual basis, it’s such a large place that you’ll rarely run into anyone else.
So not only is it easily one of the most beautiful places in the US, but it’s also a great spot for quiet enjoyment.
