“Very interesting and worth the Drive outside of Tucson”
Reviewed September 13, 2011

It is a bit expensive for a tour, but they offer a AAA discount or the same small discount if yoou pick up their brochure at the airport or hotels. The facility is big and requires a lot of walking and climbing stairs, but was so interesting and worth the trip to get some insight into science and the experiments being conducted. What a neat BIG lab, the scientists must love it!

“Biosphere 2 keeps doing new research”
Reviewed September 13, 2011

We had heard about Biosphere 2 for a long time and finally got the opportunity to visit. The University of Arizona now owns the area and is continuing to do new research; this time into what happens to water when it goes through the soil. New test areas are being constructed that will allow the scientists to track a gram of water from the air through the soil.

Biosphere 2 is interesting to anyone who can remember the project from the 1990s when 8 people lived in it for two years without ever going outside of the sphere. Now we can tour and see what has happened and is still happening with this marvel of engnineering.

Visit for a day and come away inspired.

“Don't waste your time”
Reviewed September 12, 2011

Friend and I both agree, a waste of time. I will say the architecture is pretty neat but the inside was much smaller then I was expecting. You only can see a small section of the rain forest area due to overgrowth of vegetation. Ocean area is a stagnant pool of water. Desert area has a few cactus growing. A small food area selling hot dogs and pre-made sandwiches. There's so many other attractions in the Tucson area worth seeing, don't waste your time here.

“Fascinating view of a manmade world.”
Reviewed August 24, 2011

We did this tour with guests and we all found it fascinating. Our tour guide was well informed and told us lots of anecdotes.
We bought a book about the experience of living there for two years and that it made our tour even more interesting.

“Amazing science project on a huge scale.”
Reviewed August 20, 2011

I visited the Biosphere a little over 10 years ago, went on the rather short guided tour and thought the place was pretty amazing then. I recently went again and was even more facinated by it the second time around. The guided tour was $20 per person but if you have a AAA card you can save $2. It may seem a bit hefty of a price tag, but it was well worth it. Our tour guide was very knowledgeable about the history and workings of the Biosphere. We were guided through the different biomes from the rainforest to the ocean to the desert biome to name a few. There were several ongoing experiments being done throughout the biosphere and our tour guide was able to show and describe what each was about. The best part of the tour, in my opinion, is the underground portion of the tour. It is here that we were shown how temperature/climate conditions are regulated for each individual biome and we were also shown one of the "lungs", which was used to help regulate pressure in the biosphere when it was a closed system. It is a pretty amazing engineering marvel!
One thing to note, because it is a walking tour, be prepared for climbing up and down stairs. I wouldn't recommend the walking tour to anyone who has difficulty walking at a moderate pace up hill. Also, some of the biomes are pretty humid, so dress comfortably and bring some water. Otherwise it is a great place to check out. You don't have to be a science geek to enjoy the Biosphere 2, but if you are, you are going to love this place!!
