We stopped here on our last day in South Dakota. I truly believe that there is something mysterious within the cosmos area. I've been through 2 brain surgeries & this place made my sense of balance extremely off! Some might feel that this is just a hoax or a place of optical illusion, but nothing has made me feel as...

Complete waste of money. This was the only disappointing thing during our trip to the Black Hills. It's a scam, there's nothing mysterious about this place. It's all a trick. Some things are easy to figure out and a joke. My kids 7 and 14 did not enjoy it at all. Have you ever been to Grandfather's Mansion in Silver... More

I had been here before 20 years ago, but didn't remember it exactly. The guides are enthusiastic and use some corny humor but overall were great. The initial experience in the cabin makes you question if you should have eaten before coming, but the experience is short enough that most people will be fine. It's entertainment via illusions....and they hit... More

My ten year old loved it, as adults we all just kept trying to reason why it was happening instead of the powerful forces that may be that were suggested by the tour guide. :)

We had four teenagers with us and Cosmos was something they all enjoyed. $10 each, wait time for the tour was around 30 minutes and the tour lasted about 30 minutes. Charles, our tour guide was very enthusiastic and knowledgable. The odd pull of gravity made me feel nauseas during the tour, but then resolved shortly afterwards. My recommendation would... More

Very cool. Decide for yourself, but we were so glad we checked this place out. The staff were friendly and our tour guide, Charles, was great. The kids in our group loved it. You can hit this place and be through within an hour depending on how long you want to spend in the gift shop, which was also nice.... More

Although interesting, this side trip on our vacation was solely for the kids. They thought is was very fun and my husband and I were glad the attraction took less time. Since we got done so quickly, we were able to add another attraction into our vacation plans that day.

This is an interesting place to visit, makes you wonder how things could really be this off... It's weird to watch a ball roll what appears to be up hill or to have someone you know you are taller than trade places with you to find you are now actually taller than them. Fun for all ages...

My kids ages 4, 11, 14 thought this was the best place we went on our vacation. I thought it was pretty neat myself. Definitely something different!
