We waited far too long to visit the Biosphere, an finally did it when family were visiting. It is A-MA-ZING, and we enjoyed the complete tour. Our guide was fantastic, and explained both how things were during the 'experiment' and all the things that are now being done by UofA.

Depending on your 'tour guide' - ours was very good - this is a very informative and strange look into a very unique place. Question: do you know what/where Biosphere 1 is? You'll find the answer on your tour. Be prepared for at least two hours and lots of walking and standing.

When first walking into the lobby, my first thought was that the price was pretty high! I was amazed at the size of this place, and the fact that humans could engineer a structure like this and make it completely air tight was astonishing! Throughout your guided tour you walk through several different regions of climates. Towards the end of... More

This is a unique attraction! I had never heard of this experiment, so it was fascinating to learn about it! There is a lot of stairs [around 150 of them] and walking - so not such a good place for people who have problems with that.

The Biosphere 2 is an amazing attraction to visit! It was created to better understand how natural environments generate conditions appropriate for life. B2 is a unique research facility used to study ecosystem processes under controlled conditions. It has several buildings to explore, take a tour to find out all about the facilities for a better understanding of what actually... More

If you are in the area, this really is a must to visit. It is a part of modern history, imagine 8 people living in this secured facility for two years. Now, it is an incredible research facility. The architecture and infrastructure is very interesting. Our tour was about 2 1/2 hours, and took us through the biomes, the basement... More

Short drive from Tucson. The lung was amazing. All walking, quite a few stairs to climb, interesting facts about past research and future plans. Discount for AAA membership=$18 tour cost.

Biosphere2 may have started as an idealistic science/social experiment, but it remains an active research facility today. I loved the retro architecture and the attempt to contain and represent diverse biomes within a single enclosed glass structure. Very reminiscent of the 1972 science-fiction film, "Silent Running." Plan to take the tour for maximum access to the site, which was very... More

We were able to visit with a half price coupon. At $10 a person we enjoyed it. In my opinion, the full price of $20 a person would be a bit steep. We enjoyed the tour with its interesting facts. I just wished I could have toured it back in the day after the first group of people lived there... More
