Create an itinerary including Cosmos Mystery Area
Explore the mysteries of Cosmos Mystery Area, where water flows uphill and you can sit on a wall. The area was discovered by chance in 1952, and has drawn curious visitors ever since. On the tour, you can participate in the demonstrations of seemingly reversed gravity. The illusions created by the natural phenomenon known as gravity hill are most dramatic inside the on-site cabin. Note that the tour requires navigating forest paths that are not wheelchair or stroller accessible. Bring comfortable shoes for the walk.

  • We had so much fun; highly recommend a visit here! My three daughters (15, 12, 10) thought it was “super cool, mind-blowing, and way more fun than we were expecting! We loved seeing the water and ball move against gravity! We also dug for geodes and it was so much fun to break them and watch them explode!” The staff at the Cosmos is professional, polite and helpful. The gift shop has unique, fair-priced items/food and the whole place was very clean.
  • Our whole family had a great time at the Cosmos Mystery Area! The tour was interesting and funny. Our girls (4 and 8) had a great time testing out the mystery effects. The entire staff was cheerful, welcoming, and seemed to actually enjoy working there. The geode mining was a lot of fun for the kids. I think that the Cosmos Mystery Area is an essential stop for any visit to the Black Hills.
