Once you enter the Cosmos Mystery Area all laws of nature and physics appear to be suspended. Water flows up hill, tall people appear shorter than their smaller friends and what appears to be measured level is not. Proceed further into the Mystery House and you will have a chance to walk up a wall, be mysteriously pulled sideways when hanging perfectly straight from a rafter and experience other awesome physical forces and demonstrations that can only be seen at the Cosmos Mystery Area.

I have visited Cosmos several times over the years, my first time about 60 years ago. Since then I have taken both my kids and grandkids to the site. It's always been a "Mystery" to me. But one that entertains every time. Stop by and see for yourself. - Bill F
Hard to imagine that there are spots like this in nature that seem to defy physics, but this is truly one. Lots of interesting demonstrations, and while in the crooked shack especially, it feels like gravity increased fivefold. - Agentredfox, Cedar Rapids, IA
We enjoyed a recent vacation in the Rapid City area, a family with kids aged 9 and 12. Cosmos Mystery Area tops our list when we talk about our favourite activities on our trip. It's hard to impress a 12-year-old, but even she loved it! - Eskimos10, Saskatchewan, CAN
Completely Exceeded My Expectations
We were visiting Rushmore and my husband has heard about Cosmos. I went into the visit thinking that it was going to be a waste of time. It ended up being one of my favorite parts of our trip. It is definitely a disorienting experience, but I found myself laughing over and over again. Do not miss this if you are in the area! - K O, Alexandria, Virginia
