We arrived just before 11 and got on 2 tours. The first with Sandra was a tour including the history of the Biosphere (extra $ 7 each - well worth it). Sandra got us to the general tour which started at noon with Mike (included with admission). The general tour started with a video, then included a walking tour of several of the biospheres, and the lung, which was amazing. We then did a self tour of the ocean biosphere, which was very well done.

All together, about 3 hours, very enjoyable.

We visited recently, taking teenage grandchildren. They were very impressed. It was instructional to our three generations of family, and all enjoyed.

We thought it was fascinating ! We did the paid turn - tour guide did an excellent job explaining and answering questions - understand the history and like any experiments so are successful some fail but seems like U of A with some outside funding will make a go of it again ! I thought it was a must see attraction!

This is an amazing scientific research facility run by the U of A. The tour not only explains the history of Biosphere 2, but also explains the various grand research projects underway. They include better understanding soil and water flow, and the stressors on the Amazon rain forest. The elementary and middle school kids on our tour seemed to be highly engaged.

You have to see this place to really appreciate the scope of it: there's a rainforest, ocean, and desert area. It was built in the 1980's to develop and research self-sustaining space-colonization technology. Eight scientists spent 2 years sealed inside the biosphere. It would have been interesting to see more on that: for example, a typical day's meals since they had to farm and harvest everything they ate. There was living quarters of one person to be seen - interesting to contemplate that much time sealed within a 3 acre facility. Highly recommend a guided tour as that allows you to see the entire complex. There is walking and stairs, so wear comfortable walking shoes and bring a light jacket as a couple of the indoor exhibits are cold. A small cafe provides reasonably priced snacks and drinks. We spent about 4 hours total here.
