Cosmos of the Black Hills, Rapid City

This by far the the coolest place ever! I did feel dizzy walking through it...I got the most amazing pictures of my kids and the staff was awesome they did a great job getting everyone involved in the tour. This is a MUST see for anyone going to South Dakota!

You tour a small house and the grounds for just a few mins to see optical illusions. Some things are neat but I felt sick while on the tour. The price was decent I guess....will not be going back!

We recently went to Mt Rushmore and decided to go to the Cosmos. It was great!! A family of 7 got in for $20. The kids had a blast and 4 of the 5 were called on to demonstrate. The demonstrations really had us thinking. A little hard to walk, I fell and so did my daughter, but everyone laughed ant had a great time. We had a fairly large tour group and the guide was AWESOME!!! She was funny and really made sure everyone could hear what she was saying. I cant wait to go back next year!!!

We really enjoyed our tour. I've seen some people say it was pricy, but in comparison to the other things I forked out money for...Reptile Gardens, Rushmore Cave, parking at Mt. Rushmore...this was reasonable and my 10-year-old son got in free. It's puzzling, and I don't know exactly how it is all done. Is it all an optical illusion? Don't know, don't care, it was a blast. Both of my kids got to interact. I did get a dizzy feeling, it felt like the shack was moving at times. Very cool, and it really isn't too far off the road like others have said.

It was an interactive tour! That was cool. It's hard to describe what all happened and you'll just have to go and experience it for yourself! I recommend you take a camcorder to get all the fun on video!

You go through a house for a few minutes and are tricked with optical illusions. End of story. I won't be going back.

Our 14-year-old and my husband thought it was OK, but kind of tourist-y. Our 10-year-old son loved it, but our daughter hated being involved in the demonstrations, so be prepared to be involved.

We loved this place, the kids thought it was so cool! The staff os very friendly and curtious, don't pass this up! It was one of our favorite things we did on our vacation!

I have been to the Hills many times during my childhood and always wanted to go to the Cosmos. Finally, this year, my husband and 19 year old daughter and I went to the Hills for a day. I convinced my husband to go to the Cosmos and we had a wonderful time. Cosmos is is not for grouches or the penny pinchers, no tourist trap is. If you're hard to entertain stay away - the rest of us want to have fun. Everyone in our tour group had a great time and it lasted a half hour. I can think of a lot of places that cost me more and entertained me less. I loved it all from the bent trees to the crazy house to the level concrete pavers that make you change size. The guide told us that every year people bring their own levels and balls to check out the mysteries. What fun! One suggestion: don't wear flip-flops!

was gravity really tied in a not? I'll probably never know but I don't care to the experenice only was remarkable! The guides were polite and humorous. i would reckamend this to anyone. The only bad part was we all ened it with a heasach but it was so worth it! :P
