We had a great time here with all the optical illusions. The kids thought it was great. The tour doesn't take long so it can be added to a day when you have around an hour or so to burn. It was fun listening to the story our guide gave us. Take it for what it is...fun and entertaining.

Cool place to visit with many optical illusions to keep your mind going. This is one of the first places our kids tell people about on our vacation.

Took my teenage daughter and she had fun. It is a short tour, about 30 min, but fun and entertaining. I thought it was interesting and unique. Hard to describe without ruining the fun. We had a very good tour guide which made it even better. Nice gift shop, found neat little gifts for all my kids. Would go back... More

There is no secret behind the law of gravity. Sir Isaac Newton's theory was right all along. This is just a twist and a perspective on how it works. Thanks to your physics teacher, he/she taught you right. What you will experience here will open your mind and give you an additional perspective on illusion. My next statement, however, is... More

My sister and I love this classic place. The crooked house really messes with your mind! Plan on an hour for the visit

This was so mind boggling, it was just very interesting that you could not figure out how youcould be standing up straight at a 45 degree angle.

Maybe I'm just too much of a skeptic for stuff like this, but I just didn't buy it. The tour guide seemed like a snake oil salesman. It would have been better to wander through the area ourselves with no guide in order to experience it our own way. I enjoyed the optical illusion of the cabin (because, let's face... More

This roadside stop takes about 30 minutes or so. It was a lot of fun and enjoyed by all. Weird and interesting experience. Not for people with balance or mobility issues.

My kids loved their visit to Cosmos of Black Hills. The tour guide was entertaining and did a great job using all of the kids for demonstrations on the tour. The tour is relatively short but for the price it is still a good value. You will also be given the option to do a dig at the end for... More
