After the Badlands, we continued on to the west and arrived at our next national park: Wind Cave. To say that we were pleasantly surprised by this stop would be an understatement. Again, we didn’t know a great deal about what to expect at this location…except a cave. What we found, both above ground and below, simply delighted us. From the roaming herds of bison across the prairies that we were able to get incredibly close to (in our truck) to the underground tour of some of the most amazing geologic formations I have ever seen, we had a wonderful visit here and learned so much about cave formation. In particular, we discovered a fantastic display of the largest collection of boxwork formations in the world. These delicate and intricate structures made the cave experience feel more like a fairy tale and we soaked it all in. A stop at this “hidden world beneath the prairie” should definitely be on your radar…and don’t miss nearby Mount Rushmore as well!
