Absolutely Amazing! Our guide was terrific. After the tour we were able to wonder on our own. Absolutely amazing to see and learn what research is being done here. The kids absolutely loved it as did the adults. Discount is available when you book your tickets on line. Welll worth the visit. Highly recommend!

We had some time to kill, so decided to check this place out. There are several steps down to where the tour begins. The tour guide was a little wordy so our tour lasted longer than it was supposed to. Saw a javelina on the way in, nice drive from Phoenix.

Some might call this the world's largest greenhouse, but the description would still miss the point. Constructed in the 90s and housing 4 of Earth's key environments, this massive installation was originally intended to explore whether humans could thrive in a self-sustaining closed system, sealed off from the rest of humanity. The story of the Biospherians who volunteered for that... More

So unique and interesting. I loved it. The tour was great. Unlike anything i have ever seen. I recommend it. We got a sandwich and soda in the little cafe. We drove down from Phoenix and the drive was very pretty too.

This place was so neat! Its crazy how they can manipulate and control environments inside! I would recommend the tour as well as walking around on your own and just looking around.

We have seen rainforests, deserts, and the ocean but never under one roof. What makes this experience fascinating is the tour behind the scenes to see the incredible machinery required to keep the biosphere functional. It really was a success even if the dome had to be opened after two years ... Only humans had problems surviving (low calorie intake... More

It was really interesting to walk the halls and see how the scientists lived in the Biosphere for 2 years. The tour is very informative, the guide held the interest of the kids and adults in our group. I was lucky enough to get a free ticket, but would have thought that the entry fee was well worth the cost.

Unique marvel with ongoing research. For ages 10+. Expect 3 hours minimum. We were treated to 2 tours! A history and inside tour. The docents were very knowledgeable and able to answer questions. Great sense of humor to make tours entertaining. (Claudio and Eric) We will return again to really read all the displays. Plan to read the book "Human... More

Great concept; it could have been a really "cool" attraction, but I think they missed the boat entirely. I thought the entire tour was a bit lame and outdated and not worth the $$'s spent. It's one of those attractions that I'm glad I saw just for the sole fact that I can tell others to save your money. Drive... More
