This is an impressive place that one assumes contributes to science. Unfortunately, the tour was poor in communicating this. Instead of telling us what kind of research was being conducted and why it's cutting edge, the tour focused on the mechanics--how large the spaces are, what kinds of trees were planted, how large the water system is, and so on....

We really enjoyed our trip to Biosphere, and thought the buildings were fascinating. I truly don't understand the negative reviews. The entire campus is gorgeous; really impressive. Inside the Biosphere is interesting...but...I would reiterate the other comments. The tour, advertised as an hour went on too long. We left after an hour and a half. Also, as a tour guide,... More

this is impressive facility with a great history. i was excited for this visit. but i came away a little disappointed. maybe our tour guide could have been better. i think the presentation needs to be more focused. it should probably focus on: - what was it like for the people who lived in the biosphere - what current experiments...

Although a bit dated, it was worth visiting this attraction. It was well maintained and seeing the old housing and the beautiful surrounding area made the trip enjoyable. We incorporated this visit with a short trip that included other attractions in the area. Take the time to visit this attraction and you'll see a part of Arizona history.

We stopped here on our way back to Phoenix from Tucson with several hours to kill before our late flight. The concept of people living in a self-contained environment without leaving was fascinating and I wish we had heard more detail about their daily lives and survival. Instead, after merely peeking in the rainforest area and passing through the huge... More

I was very curious to visit this place as it sounded and looked very futuristic. I was disappointed because I was expecting more of this attraction. The structure is fascinating and it really feels like you are in a science fiction movie. The price per person is $20 dollars and for what you get I think it is a bit... More

Every October, the Biosphere 2 hosts special weekend nightly events for families to enjoy their offerings. The Biosphere 2 attraction is a really nice experience because you can walk around freely both inside and outside and there are plenty of interesting people who are hosting across multiple sites. So much to see and to take in. I highly recommend that... More

I enjoyed seeing the facility and the drive through the desert to get there from Phoenix (down highway 87) was very interesting if you like deserts, agriculture and the look and feel of "the west". The science was interesting. I think I would have liked it better if there was more about the actual inhabitants of the biosphere as they... More

Great for photo ops. It just seems to me that since ASU has taken it over it's lost it's focus. Our guide stayed in the Biosphere for a week and filmed a documentary. His voice is the one you here throughout the facility. Very knowledgeable. Great perspective. Glad I visited. Unlikely to return.

Biosphere 2 was an amazing concept. It was like putting the Space Station in the middle of the Arizona desert, to see if a group of scientists could create a sustainable lifestyle, including different climates, without influence from the outside world. When you walk through the compound, you can see the skeleton of what was supposed to be an amazing... More
