Well worth a stop. Great for kids of all ages! Easy to find and a fun place to visit with the family. We stopped on a cool afternoon, and our 'tour' was just us and one other mother/son pair from Colorado. Didn't take a long time, but I'm glad we put it on the list!

If you're anywhere near Keystone or Rapid City and are looking for a fun family attraction then you need to check out Cosmos. It can be tricky with babies and small toddlers, but older kids, teens and adults will love the unique they'll only Cosmos provides. You'll be rethinking the laws of gravity and your perception of the world around... More

Cosmos is one of the unique attractions that my family and I take everyone too year after year. I still haven't figured it out! Best way to describe feeling........It makes you feel drunk inside the house. Must see to believe. The guides are professional and fun. Warning! Hold onto rails, don't let go of your kids! Again...don't let go of... More

This is one of those places you have to see to believe. I couldn't even begin to describe how amazing it is to watch my purse hanging from my hands, only leaning obviously in an exaggerated direction. Balls really do roll up hill! It's a little gimmicky the way they try to emphasize the distortion of gravity. Even still it's... More

This is a fun place to take the family especially with youth and teenagers. The gravity sensation is amazing and tricky. Try to figure out how it works....

I would recommend this place as a one-time stop. I've been there twice and although it was interesting to see again, the novelty will wear off after one visit. Prices are very acceptable! It's very cool and older kids will love it. Young kids may struggle with the walking as it's fairly steep. Also, some patrons felt nauseous after but... More

I really enjoyed how they made the optical illusions feel real with their great stories and mysterious script. I am taller than my wife in real life, but they showed me that she could be perceived as taller than I. Crazy!!! I really enjoyed my time here, but some of the scenes did make me feel quite dizzy.

This is def. a place for the kids. They make it very fun and interactive! Obviously adults understand, but it is def a mystery to kids. They have done a great update since I was there last. The gift shop is very nice and the kids also enjoyed cracking the geode!

This is a place that is so cool to see. The original house is still used and they have added a 2nd house to accomidate the amount of guests they have. Make sure you dont have a balance problem as you will not be able to stand in the house. It is like you are leaning at different angles. It... More
