Great for photo ops. It just seems to me that since ASU has taken it over it's lost it's focus. Our guide stayed in the Biosphere for a week and filmed a documentary. His voice is the one you here throughout the facility. Very knowledgeable. Great perspective. Glad I visited. Unlikely to return.

Biosphere 2 was an amazing concept. It was like putting the Space Station in the middle of the Arizona desert, to see if a group of scientists could create a sustainable lifestyle, including different climates, without influence from the outside world. When you walk through the compound, you can see the skeleton of what was supposed to be an amazing... More

This was a trip we had wanted to make for 2 years. Glad that we did. Found out a lot of information that clarified some of what we already knew. The only down fall is that we didn't take water and their machine only took cash, which we normally do not carry any more. It would have be great to... More

Tom and I are fascinated by nature, science, ecology and so much more. We made a special detour to tour the Biosphere 2 and enjoyed the tour over all. However, I agree with another review that suggested the tour was flat and not nearly as informative as it could've been. Our guide was a no nonsense guide and moved quickly... More

We are interested in agriculture so a trip here was a must. The fee covers a 2 hour guided tour into both the glass houses and the underground structure. Be aware that it involves at least a mile of walking with many steps both up and down. The guide was very informative and relaxed and very willing to answer the... More

If you are interested in ecological systems, engineering, or both, you should definitely check this place out. It is an impressive place in the middle of a vast desert. Within 3 covered acres they tried to create self-contained ecosystems including the ocean, desert, rain forest, and more. Particularly interesting were the two "lungs", huge domes that expanded and deflated with... More

This was a very interesting visit which we thoroughly enjoyed. Our tour guide was very informative and we got a little feel for what it might have been like to participate in this social experiment which predates the Big Brother TV show :-) and lasted much longer. The Biosphere had many interesting sections to explore with your guide. Moving from... More

It was great ! You don't need to be a scientist to enjoy this experience. We where only 8 people on the guided tour. Was very interesting, hot and cold at times, and claustrophobic at the "lung". Lots to see, an exercise through the science, we hardly felt the ups and downs with so many things around us. I like... More

Family trip to the biosphere 2 to see it for ourselves. There are some really great stories that go along with this creation and it's founder. Our docent provided a super recount to many historic events here. I found it super interesting ultra informative.

We thought it would be crowded, but there were only 5 people on our tour. I loved seeing the various sections, and learning the history of the biosphere, yet was disappointed to learn so little of the history of the people. In other words, we got facts about the actual building and research, but hardly anything about the scientists who... More
