This place is certainly a rare and unique place to visit. How could we not take our 9 year old daughter?!! She was a little bored walking around outside, looking at building and listening to virtual tour guides. Once we finally got to go inside, she perked up a little. We were very interested in the opportunity to share this educational experience with her but we had to do most of the exploration. We did get to ask questions with a volunteer near the end of the tour and that was nice. I can imagine the tour is much better with a live tour guide. It would have been nice to see the living quarters. I’d recommend you visit even if the tours are still virtual because it will spark questions and imagination.

Came here two years ago and had a fabulous guided tour with a young woman whose name escapes me. We have been talking this place up to friends and family for years. Recently took a group here and were horrified at how far downhill it has gone in such a short amount of time. Buildings are rusted over. Tour is now 100% app-based, you spend the whole time listening to the most obnoxious blonde woman I have ever heard of, and don’t see any of the “behind the scenes” areas like you used to. And the best part? They RAISED ticket prices! This place is an absolute scam. They have been pretending for years that they are doing this coral research project, but still no progress has actually been made. Shame on all the management involved and the university. We brought my three nephews, all of whom were planning on applying to UA, and now none of them want to go there because of how “lame and depressing” Biosphere 2 was.

A self-guided admission is $23.00, and requires you to download the Biosphere app to your phone before your tour. The mask requirement is ridiculous, since 80% of the tour is outdoors, and the governor has lifted restrictions. It takes about one hour fifteen minutes to walk through the buildings and outdoor stopping points. The app provides information along the way. I think key information was not shared on the tour, such as the original detailed objectives of the Biosphere and key findings from the 2 year experiment in 1991-92. A private donor put the money forward for this huge facility. It seems he wasted millions of dollars to ‘discover’ humans and vegetation require oxygen to live. It’s a strange place with unclear scientific objectives even now. I would not recommend.

We have made a couple of visits here, and learn more each time. The tours are so interesting. This is really a one-of-a-kind location.

Very disappointed in our “tour”. You are told to download an app and watch 18 videos as you walk the complex. While we did go in part of one of the buildings there was so little information given about the experiments that have been run and nothing communicated about what was learned from the past participants groups. There was no science at all. Very disappointed as I was hoping this would be a great learning experience for my kid but it was not at all. While I understand we are in Covid right now for the high cost of admission I would expect to be able to converse with someone about the science behind Biosphere. Very disappointed.
