Reviewed March 30, 2014

Biosphere 2 was listed on the Top 50 places to see in the US. We live in Tucson so we decided to visit today. While it is somewhat interesting, during the tour they really couldn't site any breakthrough research that occurred at the facility. The research that was underway appeared to be in its' infancy.

The facility also needs some significant maintenance. There are some places in the glass structure where the molding/caulking between the windows isn't there leaving an open space. Some of the metal in the structure is severely rusted. The downstairs ocean viewing area felt really dingy and dated.

With the AAA discount, this was $18/person. It was just okay. I wouldn't go out of my way to visit.

I'm not sure if the millions of dollars spent on this facility were really worth it but not having seen anything like this before, I wouldn't have known. The original intent of this facility was to simulate what it would be like living on the Moon or Mars. After 2 years of 8 people living here, it didn't turn out quite like they wanted it to, so they just made it into a research facility now owned by the University of Arizona. The buildings are 30 years old and showing it and I'm sure takes a great deal of money for maintenance and upkeep. Although the intent is valid, it's hard to justify why it's still in existence out in the middle of nowhere!
P.S. The Lungs, however, were quite interesting and our guide did a great job with what there was to show.

The tour runs 1.5 hours and takes you through the main buildings explaining the original experiments, through its transitional period to today as part of the U of AZ campus. There's a lot of walking and some stairs and tunnels to climb through, so it may not be for the very young or those with limited mobility. I liked how the tour guide discussed the original experiment's "failures" and how much has been learned from them. And how those "crazy science fiction" theories are now modern/current science and business models.

The entrance fee includes the guided tour, but you cannot schedule the tour in advance. We had to wait for an hour for the tour. You can walk around while you are waiting, but there is not much to see. The outer grounds are not well-marked, so we did not know where to go to see cool stuff and had to keep asking around. I was disappointed until the tour started. Our tour was about a hour and half and it was very educational and fun. I saw several very bored kids. It is not a place for young kids.

We loved this tour. The facility was absolutely amazing and it was fascinating to learn the history of the project. We had no prior knowledge of Biosphere 2, and found it only when looking for things to do in Tucson. It was a great tour, but longer than we had thought, and a bit more crowded than optimal. I found it hard to hear the guide. We are in reasonably good shape and did not find it at all strenuous. It was a bit of a drive from Tucson, but we thought it was well worth it.
