We really enjoyed Biosphere 2. I have to admit we were more interest in the science than then drama of the crews so maybe that is why we liked it better than others. We found the different climates they have in the biosphere fascinating. We also enjoyed seeing and hearing about the experiments they are conducting today. There is history... More

We traveled here after finding a brochure at resort. Long drive well worth the effort. Great tour of awesome facility led by really good tour guides. Place and goals here give mankind hope for climate change understanding and meaningful correction.

Parents take your kids here!!! Not a theme park but a awesome way to show them science in a fun environment. Hard to believe something like this exists. Great experience our tour guide was very nice and knowledgable. We spent about 3 hours there half guided and half self guided. Lots and lots of walking and stairs (remember you are... More

My hubby and I thought this would be a cool stop on our short trip to Tucson. When we entered we were greated by a gentleman advising there are two tours starting within 15 minutes. There was the History Tour or the General Tour. He didn't give clarity to what each included so we opted for the General Tour figuring... More

This place is a bit sciencey but it is so interesting too. You can follow the journey made by bunches of scientists who got locked away inside an intended model of our Earth to do some very important research. Shame someone bought their two year old along. So glad a University has taken control of the place, and it will... More

My family went to Biosphere 2 in hopes of the following goals: being given some history of the place and the people that worked in the Biosphere, being updated on the renovations and transition of the place, informed of specific research projects that were being conducted or in the process of being conducted, and just being enlightened in a scientific...

The tour is sort of interesting only from the standpoint of learning what this experiment had hoped to gain and how and why it failed. The tour is way too long for what is there. Don't eat at the snack shop - very pricey and tasteless. You are probably better off taking a snack bar and some water.

Our family and another family all went to see the Biosphere 2 this past weekend and it was disappointing to the say the least. We were the last tour of the day and essentially the entire tour was 5 minutes on the tiny balcony looking at the rain forest, a walk past the 'ocean', a walk through the desert and... More

Worth the time to take the tour and learn all sorts of things from agriculture to immense HVAC equipment, to survival experience. Worthy for all ages.

This was on a friend's bucket list and we went along. It's much larger than I thought it would be. The concept was very interesting and while it shows it age a bit, was certainly worth the trip. The Biosphere2 (earth is biosphere1--if you were wondering) is currently owned by the University of Arizona and is used for research. We... More
