    Tour spoiled badly by insistence of guide to insert editorial opinions about causes of climate change, including the phrase "that harmful gas CO2" on several occasions. Also insisted on adding silly propaganda re: extreme/catastrophic consequences of possible future climate changes in a clear attempt to frighten customers. VERY unprofessional and VERY unscientific. This tour guide needs retraining or relocating to a different line of work. For me, he embarrassed himself and the entire concept of the Biosphere2 project with his unscientific comments....Read More

    This will sound like a lot of the other reviews, but I too was very bothered by the tour guide! It was great to see the Bioshpere2 and the engineering that went into it, but having to listen to the tour guide rant about his personal beliefs and feel like we were being lectured the whole time really spoiled the day. I normally don't write reviews, but after listening to the tour guide talk about how he believes in following the law, then to have him go into telling how some of the plants and trees were brought in illegally by a gentleman because...Read More

    There is nowhere else on Earth like Biosphere 2. The complex itself is a marvel of engineering and the past and ongoing science behind it is fascinating. Science can benefit as much from unexpected results and mistakes as it does from "successes," so the initial highly-publicized original experiment was certainly not a "failure".

    The worst part about the tour was the tour guide. He was rude, impatient, and nearly disinterested in what he was saying. I really wanted to give a 5-star rating, but the Univ. of Arizona (owner of B2) should be more...Read More

    My grandmother and I went on the guided tour and were amazed. It's more than about the biology but the fats of human ingenuity and engineering that made it possible. Our tour guide was amazing.

    Fascinating history and some of the areas were truly awe-inspiring. Our visit was pretty much ruined by our tour guide though. She was just horrible and painful to listen to. Flip-flopped back and forth from being defensive and self-congratulatory. Screeched at us and harangued us for nearly 10 minutes for not taking care of our planet! Very disjointed presentation. Film at the outset of the tour was primarily a marketing piece. If I ever go again I will certainly take the self-guided tour.

This tour guide needs retraining or relocating to a different line of work. For me, he embarrassed himself and the entire concept of the Biosphere2 project with his unscientific comments. They added nothing to our understanding of the Biosphere2 facility. However, if these opinions are actually official Biosphere2 positions the tour guide should say so at the beginning so that customers can decide to stay or leave at that point. Springing these views on us in the middle of the tour ruins everything else he says.

The University of Arizona is trying to turn the Bioshpere2 into a money making tour machine and they are letting the structure rust in places and need to be careful if the tour guides are turning people off by spouting their personal opinions. The tour guide also kept asking for the group to send other people their way that would want to see the tour.

After seeing it once, I would have a hard time recommending someone paying the high admission price. Seeing the Karchner caverns was a much better outing.

I really wanted to give a 5-star rating, but the Univ. of Arizona (owner of B2) should be more careful with their public relations. The tour guide is really the only significant representative guests are likely to meet.

Great for: Adults and teenagers, science/engineering or recent history buffs, inquiring minds...

Not great for: Young children, people who have difficulty with stairs
