“A Little Out Of the Way - But Worth the Trip”
5 of 5 stars Reviewed December 31, 2012

Went early in the morning in late December 2012. We only had 20 people on our tour. The tour guide was very knowledgeable about the Biosphere 2 - both the first and second mission - and the current mission - LEO which is being put together to start shortly. The building is amazing and love that Arizona State University is continuing the use of it to understand more about the planet (Biosphere 1). There are many stairs, but it is not taxing. The total walking trip is about 1 1/2 hours - and you do walk that long. Very informative.

Go early in the morning - it opens at 9 - get there as close to that as possible. The tour people told us that the tours in the afternoon have many more people in them then the morning.

“Great visit!”
5 of 5 stars Reviewed December 26, 2012

Victor led our group on 12/26. I was a bit skeptical, but our family (mom/dad, 7 & 9yr old) really enjoyed it. It was educational, both regarding the environmental science being developed now, as well as the history of the Biosphere 2 experiment. Really well worth the time.

“How about a refund?”
2 of 5 stars Reviewed December 22, 2012

Youprobly need tobe earth worm or a scientist to actually enjoy this. After dropping $100 for the tour and $30 for hot dogs we were very disappointed with this trip. Bring back the animals and clean this place up. The amount of rust on the structure is pretty disturbing. The best part of the tour was the kid who lost his lunch in the jungle room. O.r tour guide was not interesting and went passed the hour and a half tour. We didnt even get to see the full room of the scientist

“Tax deductible attraction”
4 of 5 stars Reviewed December 14, 2012

I would agree that if you like science, you'll like Biosphere 2, however you don't have to be scientist to appreciate what the University of Arizona is doing here for mankind. The admission is $20 however there is a $2 discount for AAA members, Seniors and military. The best part is that the admission is a donation and thus, a tax deduction. We arrived 30 mins prior to the next guided tour which gave us just enough time to get to the theater where the tour begins. I would recommend the guided tour but you can also go at your own pace. After the 90 minute tour, you are free to explore on your own. This is a large facility (3.14 acres) and there are steps and slopes to climb. I must admit that after reading the reviews, I was not sure I would enjoy this but we (2 couples) all did. The ride from Phoenix to Oracle was about 90 minutes but the scenery is so enjoyable.
The University of Arizona College of Science is known as a world leader in teaching, learning and discovery. As a trailblazer in the fields of astronomy, ecology, evolutionary biology, geology, hydrology and tree-ring research, the College of Science has established an international reputation for excellence. Arizonans, you should be proud.

“Unexpected delight!”
5 of 5 stars Reviewed December 13, 2012

When I'm normally on vacation, "science" is not a word that I find alluring. So my expectations for a trip to the Biosphere were luke-warm. Boy, was I surprised. The tour explained what the Biosphere was originally - an experiment where 8 humans lived confined and insulated from the outside world in an attempt to learn what it might be like for humans to live in a space station on another planet. But it isn't that anymore - so what to do with this small city-size greenhouse structure? Now under the auspices of the University of Arizona, the research being done here is fascinating - all about studying the earth, particularly the effects of global warming. The "lung" was most intriguing - like walking onto the brig of the Starship Enterprise! The engineering that went into the design of this place is just astounding. I never expected to have such an emotional reaction to "science" and I was awed! Be prepared for walking and lots of steps - but worth the climb! Be prepared to use your brain and your imagination! (Not the place for children unless you've got one really interested in science.)
