A fun place to visit. - This was our 4th visit to the Cosmos and we enjoyed it as much as the first time. Our tour guide, Trig, did a fantastic job of making it very entertaining. Our grandchildren really enjoyed the entire experience. Definitely something to check out if you're in the area.

Worth the stop - I brought 3 teens and they loved it. It’s a nice quick stop along the way to Mount Rushmore. William, our guide, was great with corny jokes.

Family Fun - Cool Experience for the whole family. Everyone should check this out if you’re in the area. Be aware that there is some climbing and you need to have solid lower body strength. 5 and under might want to reconsider.

Kind of fun, good rainy day activity - This science defying mystery tour lasts 30 minutes for $10, ok price. Kids and teens would really like it. As a couple we enjoyed it too, our guide Trig was super funny. Not a must see, but on a rainy day it was a great add on to our trip.

Bendy trees and water that runs uphill. - Very fun….make sure you are able to “hike” up the side of a mountain…steep terrain even with the paths. The illusions are pretty cool to experience. But i will say if you have any history of motion sickness….this place WILL challenge you. We also purchased the geode hunt & cracking. Granddaughter liked that part alot too.
