This exceptional piece of South Dakota prairie of rolling grasslands, pine forests, hills, and ravines has a hidden secret-Wind Cave. Perhaps one of the oldest, longest, and most decorated caves in the world, this cave's labyrinth has only been five percent explored. Its flowstone, boxwork, honeycombs, frostwork, popcorn, and helictite formations are among the best examples in the world. Two worlds, one park.
