It's a very interesting place. Tour was very educational for kids and adults. Plan to spend about 2.5 hours there. Moderate walking involved. Tour guide seemed very tired and wasn't really interested in taking questions.More

Wasn't really sure what it was until we got there and took the tour. Tour takes about 1 1/4 hours - very worth the time. Quite the experiment undertaken there.

This place is amazing. Before you go, read the web site about the construction and the two experiments with sequestered living. It's a great story and an engineering feat.
