What people say

Grace Nesseth
"OKAY WOW!!!!!! The Biosphere II was such an awesome stop! We didn’t know about it until we were halfway through Arizona and we are so happy we stopped! It is the second largest Biosphere - the first one being EARTH! The place is just one big science experiment! The craziest part, scientists trapped themselves in here for 2 years to study it all! There is an app that you download to go along with the tour and it gives you information at certain checkpoints. Price: $25 /person"
