This Cave In South Dakota Is So Enormous, Only 3 Percent Has Ever Been Explored

South Dakota is home to some incredible natural wonders, but not all of them are fully accessible to us. Jewel Cave is so large that while 180 miles of passages have been mapped, that portion only accounts for about 3-5 percent of the estimated total volume of this magical wonder. Take a guided tour to see some of it.

Have you explored this cave? If so, what was your favorite part of the trip? We love to hear your feedback and comments.
