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 ...

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? ...

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 ...

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

We LOVED cosmos and would love to go back sometime just because we could not get enough of it. Our tour guide (Keegan) was awesome and made the whole experience that much more amazing. Our tour lasted about half an hour and it was the best eight bucks person that I spent in Rapid City. Bottom line: Cosmos Rocks!!!
