My family went to Biosphere 2 in hopes of the following goals: being given some history of the place and the people that worked in the Biosphere, being updated on the renovations and transition of the place, informed of specific research projects that were being conducted or in the process of being conducted, and just being enlightened in a scientific...

The tour is sort of interesting only from the standpoint of learning what this experiment had hoped to gain and how and why it failed. The tour is way too long for what is there. Don't eat at the snack shop - very pricey and tasteless. You are probably better off taking a snack bar and some water.

Our family and another family all went to see the Biosphere 2 this past weekend and it was disappointing to the say the least. We were the last tour of the day and essentially the entire tour was 5 minutes on the tiny balcony looking at the rain forest, a walk past the 'ocean', a walk through the desert and... More

Worth the time to take the tour and learn all sorts of things from agriculture to immense HVAC equipment, to survival experience. Worthy for all ages.

This was on a friend's bucket list and we went along. It's much larger than I thought it would be. The concept was very interesting and while it shows it age a bit, was certainly worth the trip. The Biosphere2 (earth is biosphere1--if you were wondering) is currently owned by the University of Arizona and is used for research. We... More

I had heard of Biosphere but never thought i could visit it until i realized its located between Phoenix and Tucson. I was impressed to hear about not only the history behind this great experimental place but also how it is now used by the U of Arizona for ongoing research. Your tour consists of a video, followed by a... More

It's very difficult to summarize a long docent led tour of this fabulous experiment. Maybe it wasn't the success everyone hoped for a number of reasons but to view this project now and witness the scope and the redundancy built into the structure it's hard not to be impressed. I read where someone was really disappointed and it's true that... More

I'm happy that I went on the tour, because, at one time - this was a really cool place... and what a fantastic original idea, studying different climates, biomes, suitability, conservation, recycling and reuse, creating a possible further space station environment... But, I was a little disappointed, 20+ years later... Now, it seems somewhat run-down, and I didn't get the... More

This huge project that was a totally self-sustaining experiment is very interesting to visit. Amazing to see how they created 5 different climate zones inside.

The biosphere is huge. You can have the chance to explore the grounds on your own or sometimes there is a history tour offered before the Biosphere tour. I would recommend the history tour (unless you need to save your walking energy for the real tour). It is a lot of walking, and there is one place inside that you... More
