Cosmos Mystery Area

Baffling, funny, great stop for family vacay. Nice gift shop, friendly guides, fairly quick stop (1 hr). Kids can dig for geodes and crack them open.

Very interesting stop on our road trip. You can feel the change in the gravity the moment you step inside.

Cosmos Mystery Area

The Cosmos Mystery Area people were pretty secretive about their place for some odd reason. They were quite proud of the fact that they recently had been mentioned on the Letterman Show (I hate it when these small attractions go commercial). They were not crowded, but we were there in the off season. One lady not in our immediate group complained of nausea...but none of us got sick. We have some great pictures of all of us standing in the main building and seeming to be leaning straight out from the side wall. Great place...We highly recommend it.
