Cosmo‘s is AMAZING!! Be ready for a tiny walk to get to the fun. My youngest and oldest both loved this experience.

2 croocked cabins to explore nestled among natural surroundings of a wooded hillside. The gravitational pull is so strong that it caused me to feel a little dizzy and nauseated. To help combat that feeeling I kept eyes forward and level. If you are prone to vertigo, perhaps this attraction is not for you. Aside, from a little discomfort, it was quite remarkable to experience the opposite of the law gravity as we know it. Guided walking tour approximately 30 minutes.

Yes, I knew going into this, it really has to do with optics/illusion, but still piqued my interest. I read about dizziness and such on the reviews, but that didn’t apply to me. Or, did it? Yes, it did. Now I know why there was someone else waiting for their group to finish the tour before we headed out. I’m older, so that may have something to do with it, but I could not finish the tour, as I felt so disoriented. Thankfully, there were handrails. We bowed out half way through the tour. Still felt dizzy a half an hour later. I can’t discredit the place. Even though we didn’t get the whole experience, it was still a cool experience. The kids in our group had a blast! Probably too much fun, as some little rug rat (lol) kept running and falling into me. The other (younger) adults in our group had fun as well. Not sure why the address is listed as Rapid City. It is just outside of Keystone.

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.
