We didn't realize how far away the Biosphere was from Scottsdale, so we didn't get there until the last tour was about to depart. It's in the middle of nowhere and is quite an amazing place. The history is fascinating and our guide obviously knew his stuff. We watched a short video and then we were taken through the different... More

We really enjoyed our stay - from the drive there to our tour. We were disappointed the cafe was closed so early, but otherwise our stay was excellent. The cafe is only open from 11-2. The tour was a little over an hour and seems to start at the top of every hour. Our guide was very informative and extremely... More

Biosphere 2 is in a beautiful setting. One glance and you could be stepping into the future. From the architecture of the buildings to the facinating life sustaining facts, this is a whole new type of adventure for you. When you walk out of this "compond," you have learned so much. Wonderful experience. More

The Biosphere2 was a fascinating tour into a piece of history while providing a glimpse at current environmental studies. The guide was so knowledgeable that I secretly wanted to play a game of "Stump the Guide" but it was no contest; he would've won. The scenic drive from Tucson was also rewarding. If you're on the fence about whether to... More

It's just OK. I wouldn't go way out of your way to see this. This is one of those things where the photos and advertisements are really cool to look at, but when you get there, you think, it was OK, but not all that. It's not a place to go if you have difficulties walking as there are stairs... More

Go before it gets too hot, as it is in the middle of the desert and there is a fair amount of walking to get to the actual tour facility. Keep children close, as there are snakes and can be very hard to see. They are not aggressive to humans but, if startled, the situation can turn. Just back away... More

I had purchased a groupon for this. My boys are 7 & 11 and we all loved it! What a great tour. I loved hearing the history of how the biosphere came to be and who all has owned it over time. I was surprised to hear that U of A has only owned it since the summer of 2011.... More

Biosphere 2 is such a unique place. It was first created as an experiment in creating a closed system that was nearly all self-sustaining. About 20 years ago, a crew of 8 people spent 2 years living in the Biosphere. It was closed to the outside world so the crew had to produce all their own food as well as... More

What a remarkable, unique place! A microcosm of our world, where scientists are tackling some of the big issues facing the planet. You are, literally, visiting a university science department, so it's not your typical Disneyfied tourist attraction -- it's a lot better. I've been fascinated with this place since reading about the project to sequester a crew of people... More
