Wind Cave is a fantastic national park that often gets overlooked in comparison to its more famous neighbors in the Black Hills of South Dakota. We are here to tell you—you should definitely add Wind Cave to your Black Hills vacation itinerary as it is not to be missed! Touring one of the most unique cave systems in the world was a lot of fun for our entire family. Afterwards, take a lovely hike through the prairie where the kids can now say they have walked over and under the same part of the Earth. Not something you can say too often! And to make it all even better, the wildlife watching was some of the best in the Black Hills.
