  • Wasn't impressed with Bio2. Having lived in Tucson for over 50 year, we thought we should go see this "must see" attraction. The architecture of course, is impressive. The huge glass structures, the g...  more »
  • One of the coolest sightseeing stops I have ever made! Highly suggest going at least once. Be prepared to spend longer than you think you will have to. Also be prepared to walk during the tour throughout the biosphere! Can't wait to get back there again!
  • A truly remarkable experience. We well spent over 3 hours on the guided tour, and then following, in further exploring the internal systems, the science exhibits of various types as well as the project team quarters. This is a really big, BIG complex, much larger than I expected. One heck of a lot of walking though the park like setting. That said, were ample refreshment, test and bio break stations which made it very pleasant for our party of 7, comprised of 3 generations old and young. A massive construction accomplishment too, as well as an true engineering marvel. The fact that the Biosphere 2 can maintain 3 distinct climate zones, self contained in such a way such that could have been located on the moon or Mars (a design goal), rather than in the desert, just blows me away. The only other Biosphere that does this is Biosphere 1... which (I learned) is planet Earth. The giant "lung" in the basement that compensates for changes in air pressure, necessary due to changes in air temperature, was frankly amazing. A must to experience first hand. BTW, the tour guides are excellent. I asked a ton of questions and all were answered quickly, clearly and in a way that added depth and color to my understanding. I plan to visit again soon as we ran out of time and so did not go on the history tour.
  • I absolutely loved it! The architecture, science, history, and tech are amazing. I would highly recommend the trip. There are a few places on the tour where you need to be able to bend your back and there are quite a bit of stairs but they lead to some really cool places. Again, I would highly recommend!
  • Highly recommended.... EVERYONE needs to understand their impact on our environment. The endeavors of this facility will help us realize what we can do to lessen our negative affect on our environment. Very informative and motivational in encouraging us to adjust our ways to improve our environment.
  • So knowing about biosphere will be helpful. It was a grand experiment in sustainable living with what you can create. Air water food and sustain human life. To go back and be able to see the environment that they created is fascinating and amazing. And doable. We thoroughly enjoyed this guided and self guided tour. Very informative. I definitely recommend it. Experiments are ongoing. To see how we can sustain life without the support of the planet we live on. Say, we need to relocate. The staff is super friendly and very knowledgeable. And they really like what they are doing. Go see it. You won't be disappointed!
