About This Deal

Visit: Cosmos Mystery Area, 24040 Cosmos Rd, Rapid City, SD 57702-7414

The mystery house located within the Cosmos of the Black Hills was discovered in 1952 by two college students who were looking for the perfect place to build a summer cabin. Here, the laws of logic and physics seem to be turned upside down as you feel a slight unbalance in this crooked old cabin. 

Admission includes a 30 minute guided, interactive tour where you will be amazed as you see water run uphill, can stand on a wall, and see other incredible optical illusions. The tour consists of various demonstrations that are designed to boggle the mind.  

Located just minutes from Rapid City and Mount Rushmore, The Cosmos is sure to astonish and amaze the mind.
