A nice day trip from Phoenix. A close up look at the way our world works. Not as much about the initial experiments that created the bios-sphere. Be sure to check out the "Lungs" and peek back in once you leave the room.

The architecture of the future was so beautiful to me. It was very "Buckminster Fuller" in design. Since we went during the winter holidays, they didn't have tours, just self guided experience which was great for us. We had about 2 hours to see it...More

Over 100,000 visitors tour the Biosphere each year. If this is Biosphere 2, where is Biosphere 1. The answer is you are currently living on Biosphere 1, the earth. The University of Arizona now owns and runs the Biosphere 2 and they still conduct science...More

Not overly impressed. Years ago it was state of the art technology, but today, seems like a location looking for a purpose. It would seem that the majority of the experiments were not failures, but we're not successful either. Some of the areas had a...More
