Explore the mysteries of Cosmos Mystery Area, where water flows uphill and you can sit on a wall. The area was discovered by chance in 1952, and has drawn curious visitors ever since. On the tour, you can participate in the demonstrations of seemingly reversed gravity. The illusions created by the natural phenomenon known as gravity hill are most dramatic inside the on-site cabin. Note that the tour requires navigating forest paths that are not wheelchair or stroller accessible. Bring comfortable shoes for the walk.

Cosmos Mystery Area Reviews
Stand on the walls and balls roll uphill. The 40-minute tour is great for the kids. They haven't updated much from when I was there 15+ years ago but still was something to bring the kids too. more »
You will walk away scratching your head wondering what just happened. A great place to stop that will have you talking about for years to come. more »
This place is truly mysterious. You can feel and see the energy change in the area. At first I felt queasy inside the cabin, but as I adjusted that feeling went away. However, throughout the time at the location my balance was off kilter. If you look at all the trees grow in an arc over the area. This was the most mysterious part of the experience in my book. Don't forget to go through the geode breaking attraction. You can pick your own geode rock which they crack open for you to reveal the crystals inside. This was my favorite souvenir.
Wonderful place. Wisdom and awesome staff(Jake). Jake was a great staff in here. The tour is exceptional. But be careful of headache. This area was so weired, but it was funny. Would recommend this place to explore something new!
