What are the most well known parks in South Dakota?

There’s no shortage of amazing parks in South Dakota. One of the most popular parks, though, is without a doubt Badlands National Park.

  • Equal parts expansive and stunning, the park spans 244,000 acres and boasts striking geologic deposits, an expanse of mixed-grass prairie, and lots of other unique natural features, including the Fossil Exhibit Trail, which is a boardwalk trail lined with displays on fossils discovered in the park. Wildlife is another park perk.
