This was surprisingly a very good visit. Lots to see and learn about life in a Biosphere, the history of the project and the challenges the crew had to do to live in the structure. Good for the kids to learn about an enclosed habitat and the life under it. A possible future for all of us...

We decided to make the trip to Biosphere 2 after thinking about it for many years. The tour is informative and very interesting. I could not imagine living in there for years sealed in, however it was not as if they were living in is a cardboard box with no windows. The habitat was nicely accommodated and with a great... More

Although this place was only used as a "closed system " in the early. 90" s it is still operating to do experiments in an "open system". This place originally cost $150 million. The engineering that went on to allow folks to live for several years is amazing. The systems had applicability for space programs and other futuristic endeavors. It... More

I read a lot of negative reviews online before my visit, but family members promised me it was a great place to visit, they were right! It is incredible to me that so many people write reviews saying it is bad place to visit because there are stairs (oh no! excercise!) and peeling paint (oh no! they spend money on... More

Despite what others may say, this is an interesting place to visit. Yes, there is some peeling paint etc, and yes, there are stairs! (when did the human race become incapable of using stairs?) However, personally I feel that unless you are of a certain age or have walking difficulty the whole site is manageable for most with ease. This... More

It was great to see green in the desert. The amount of stairs and walk was little much for us though. Make sure you can walk quite a bit before starting.

The coral reef is dead. There are no animals. The structure is rusty paint peeling everywhere, The kiosks are all broken......none worked. The guide was rude. The roof was leaking rain in numerous places.....save your money and time......Very disappointed. TOTAL RIP OFF. I'll bet it was impressive when it was working.

The Biosphere 2 is a very interesting tour. They mention 100-150 steps - that is NOT all at once. It is just that the entire tour has steps here and there, more like 10-20 at a time. So little kids are perfectly fine during the tour also. They had about 15 people in our toured group. Part of the tour... More

Went here on a whim at the suggestion of my college-aged son and it was well-worth it. Probably best to visit either early in the day when it first opens or wait until November through April if you don't enjoy the heat. That being said, the tour was both educational and entertaining. Our tour guide, Ren, was terrific and informative.... More

During a trip to Arizona, this was one of my favorite stops. I never knew it existed until I was exploring and happened to read about it. I enjoyed exploring the various ecosystems. It is unfortunate that they were not able to continue this experiment because I believe it would be worthwhile. Great place for children, but try to come... More
