Not all national parks and monuments in the USA get the same amount of love from tourists. So while the Great Smokey Mountains will get more than 9 million visitors a year

Given its remote location and notoriously bad weather, Aniakchak is one of the least visited units of the National Park System. A vibrant reminder of Alaska’s location in the volcanically active “Ring of Fire,” the monument is home to an impressive six-mile wide, 2,500 ft. deep caldera formed during a massive eruption 3,500 years ago.

So that makes Aniakchak one of the greatest sites in the national park system that you will likely never see.
