“An Engineering Marvel !”
Reviewed 10 August 2014 via mobile

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 is worth several hours of driving to visit this place. Cost $18 with AAA discount.

Thank John T

“Great Walk Through Science Experiment!”
Reviewed 6 August 2014

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 experiments, not aesthetics!). This place is Earth on a few acres. That is incredible! They are able to do large scale experiments like no where else on Earth. It is amazing to me that people actually lived in this placed, sealed inside. The whole place is an engineering marvel in the middle of the desert. Our guide was awesome, she was intelligent, she knew about all of the experiments, she knew all of the history, and she treated the idiots in our groups like idiots, maybe that is what some reviewers were referring to. I wouldn't take small children here, they probably wouldn't appreciate it. I, on the other hand, really appreciate the scope of the entire project and respect the incredible work that is being done in each of the biomes. The rainforest was my favorite, by the way, but the fog desert was pretty cool too!

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 is no longer a sealed environment, therefore it is not as it was in the early 90s. There are a number of interesting experiments taking place now which the guide told us about. Trying to imagine living inside this structure is quite difficult, although it is helped by glimpses of the former living conditions.

I would hesitate to describe this structure as a museum. It is not a zoo, or botanical garden. It is a scientific research facility which is run by a university and is open to be public because of its unique past, and the contributions it is making to human knowledge about Biosphere I, The Earth.

Certainly for those with a smattering of knowledge about climate change, food production or an interest in plants and natural resources, this will be a few hours well spent. They are currently working on improving the ocean facility, with viewing glass and displays which would appeal to younger visitors, however apart from this, the rest would appeal to older students only I feel.

It is unlikely that something like this will be built again...especially with private funding, so for this reason alone it is worth going to see the oasis in the middle of the desert!

“Something in the desert”
Reviewed 24 July 2014

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.

“Place is falling apart don't waste your time.......”
Reviewed 20 July 2014

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.
