Biosphere 2 is truly a marvel of engineering and scientific discovery. Though it is used for different research today than what was initially envisioned for it, Biosphere 2 remains relevant in terms of research and as a means to educate the public about the scientific process. As I entered the Biosphere, I imagined what must have gone through the minds... More

While this isn't a venue I would want to go back to again and again I very much enjoyed the trip this weekend. We ended up taking the history tour that they only run at 2pm on Saturday/Sundays currently and it was great. An amazing place engaged in some very interesting work.

After visiting family in this area for almost 20 years finally made it to Biosphere 2. Glad we did. the overview tour made us want to learn more and wish U of A success with all of their projects (and funding). We, Earth, needs more research like this!

We had heard (a long time ago) of this experiment of people living inside the closed biosphere for 2 years, but knew almost nothing more about it, so were excited to visit. We were amazed at the scope of this place, and the planning, engineering, and science and vision needed to create the complex. The tour guide was good. The... More

This was a great way to spend just over 2 hours. The guided tour is a must. You can walk around by yourself and many of the exhibits are wonderful but honestly you miss going into certain areas and the guide has so much information. The guided tour starts with a video and then a tour of the facility. Was... More

What an amazing experiment to see up close. The tour guide kept a well balanced approach to the original and current use of this great facility. The U of A has done a great job keeping the intended use up.

Great guided tour through Biosphere, interesting to learn how this helped NASA plan for space station living. So many challenges they had, hard to imagine what their two year stint was like. The tour of the building's 'lung' and understanding the massive forces involved in large-scale air handling was amazing.

This was an attraction option that we chose with limited information. I thought it would be a typical science centre and wasn't certain that we would be entertained. Other reviews seemed positive and piqued my interest enough to make the 2 hr drive from Phoenix. We included a visit to Colossal Cave to add some value. It was worth the... More

You have to drive a bit from Tucson to get to the Biosphere but the trip is great since you see the mountains along the way. Beautiful. If you do not have a Tucson passport, you should consider buying one since you get a buy one admission, get one free for this attraction. Since it costs $20 per adult and... More

They won't tell you that if you are paying for 2 adults it's actually cheaper to get the membership. Without the guided tour this wouldn't have been worth it. It's more about what they are doing with it now than in the 90s when it was a closed environment
