Love the tour of the Cosmos. Someone tried to explain it to me before we got there, but then I got what this person was saying once we took the tour. It's interesting how all the tree in certain areas of the Cosmos are crooked, as well as the house you walk in on site. The tour guide was informational... More

I vaguely recall visiting this place in my youth, but—full disclosure—that was a long time ago! We had heard from some folks who had taken the tour recently and recommended we do the same. The drive into the place was an interesting one. The road is not paved and there were potholes that looked as though they could swallow up... More

This an't realy an atraction its more of a must experience the real thing its so strange its not logical you have to go with a guide and I found it worth the admission fee certainly a place not to be missed

This is more for children maybe 5 and up. Participate in a bunch of experiments to help you experience disorienting illusions. Can make you queasy. Lots of walking. Fun place

Very interesting to try and figure out how your senses are being tricked. Disorientating at times. Can get some folks feeling queazy. Just close your eyes and stand still if that happens.

This is a place to think about for a long time afterwards. The effects placed in and on your mind are hard to explained except to say the illusions are such that there seems to be truth about what is experienced. A must see and do.

Our family had the best fun and laughs here....... It's soooooi unexplainably weird but great at the same time. Nothing makes sense and it's so bizarre, it's insane! It's worth every penny to visit, we all loved this place and still talk about it and laugh about our experience here!

Been going there since I was 5 years old. It is cool!! Can't be man made! Freakest thing ever! I saw it before it was a "tourist attraction" , just a dirt trail and no admission cost!
