My wife and I visited this for her first time and my second time. We spent about two and a half hours at the Biosphere 2 total for both the tour and to look at exhibits afterwords. It was about an hour drive north of the Tucson airport. I would say that if you are within about two hours of... More

Biosphere 2 is both a fascinating look at current scientific research and a wonderful history lesson about the mission in which 8 people lived in this facility for two years. The structure itself is incredible and a big photo opportunity, as is the beautiful area in which the facility is located. Our tour guide, Kat, really brought the history to... More

We chose this one-of-a-kind scientific, working museum out of curiosity and came away much more impressed and enlightened then before. Our tour guide was extremely knowledgeable and enthusiastic, answering questions and encouraging further exploration.

Went with my brother and sister and their spouses as an activity that crossed interests and very different personalities. We all enjoyed Biosphere 2. My brother took the special 2 p.m. tour that was led by a scientist who was one of the original Biosphere inhabitants in the early 90's (1 hour tour) then took the final normal tour of... More

We stopped by this place on the way back from Sedona, this place is very cool, it starts out as a guided tour, showing the different sciences that were involved, and history and the work that is still on going there. After the tour, you are permitted to go out and about on your own, and check out the habs,... More

I had heard about Biosphere2 but didn't know what to expect. You go thru 6 climates. There are about 200 stairs to climb in the 2 hour visit. The cost is about $20 per person but if you are going to be in the area for a few days buy the 2 for 1 book for $18 dollars and if... More

Beyond a doubt, a visit to the Biosphere 2 is a unique learning experience ... The tour was very complete and informative ... If in the area, it is well worth a visit ... It is very, very "different."

From previous reviews I had read to do the self tour and this is no longer possible so to get inside the dome you must have a tour guide. It started out OK but then facts were repeated that we had read on the walls while waiting for the tour. My husband had read about the dome many years ago... More

This was the highlight of our trip. To see and hear of the work that has been and is being done here is not to be missed. Our guide was well versed in the history and the continuing experiments and kept everyone in the group involved and asking questions, I would suggest you google 'biosphere 2' before going for some...
