We are Cosmos fanatics. My dad's whole family practically worked there in their teen years - and have many wonderful stories to share. We visit annually or biannually and don't let friends who visit the area leave without a trip to Cosmos.

This place challenges you senses. Balls roll up hill and you can through them around a corner. You stand on th walls and watch water run uphill. Great family fun.

The Cosmos Mystery Area is an enjoyable time for the whole family. You walk through a number of different buildings and areas that challenge your perception. My kids were under 12 years old when we went, but it is really a nice place to go with kids even older than that. The "tours" leave often from the gift shop, so... More

This place really gets you trying to figure out why it works the way it does. My favorite part is when you walk into the cabin and it does not seem right. Kids of all ages will consider it fun.

The attraction is fun, but there is no "weird" things going on there. The building is set at an angle so it makes you be at an angle. All you have to do is look out the windows and see that you are standing straight, just as the trees are. But it was entertaining and my family liked it. I... More

Totally worth a stop--this is one of those water goes uphill, weird gravity spots. We had a good time even though it's a total tourist trap. We're looking forward to going back with visitors!

A house in the magnetic field. The admission charge is excessive as far as we are not even lucky enough to see closely the original house. The young guide thought funny and only some people were able to experiment certain phenomena. In brief, a place where I would not return.

Interesting, but just a building that shifted, which gives the appearance of things defying gravity. It plays tricks on your mind with optical illusions, but there's no "magical force" as the tour guides lead you to believe. Fun to do once, but overpriced and touristy. So many more beautiful and natural things to see and do in the Black Hills... More
