America’s national parks have become a popular escape for millions of travelers. They bring a unique variety of gorgeous landscapes, various wildlife, adventure sports, and incredible scenery. No doubt you’ve heard of the Great Smoky Mountains, the Grand Canyon and Yosemite. They were among the most visited national parks in 2015.

But how many designated national parks have you been to? If the answer is none, you’re missing out on “America’s best idea.”

For every park where masses of tourists frustrate you and prevent you from reconnecting with Mother Nature, there’s a magnificent piece of land someplace else that’s wonderfully wild and uninhabited.

Check out a few of some of America’s lesser known, but stunning, national parks.
