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 I thought the entire tour was a bit lame and outdated and not worth the $$'s spent.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

We had read about Biosphere 2 long ago, then were reminded of this amazing experiment by a TED Talk by Jane Poynter. The TED talk piqued our interest so we made the trek from Tucson along with another retired couple. We're all pretty science oriented to it was very interesting to listen to our docents as they led us through... More

It was very interesting. There was some steps to climb. Some of the air was very humid. Not good for someone who has breathing problems. We are glad that we went while still able

Take a tour, otherwise it doesn't mean anything. I'm a scientist by background, so the technicalities I understood. However, it struck me the next day that the whole artificial setup really drained my energy walking through it. Judge for yourself. It's a novelty worth visiting once.

There is a lot of walking and steps on this tour, and they are very upfront about that. It is interesting to see the film in the information center, as well. Taking water with you on the tour is a good idea. The story about the "mission" here and the historic experiments is all very interesting. We thought it was... More

I guess that I'll touch on other comments first: yes, there is a fair amount of walking and steps. Definitely not advised for anyone with mobility (walker, scooter, wheelchair) needs. For folks with those needs, you can do some self-guided exploring, but seeing the full facility won't be able to occur. Our guide (Brian) answered every question that anyone asked.... More

When I first saw the Biosphere 2 buildings I though of futuristic Aztec temples and cities as well as the movie Silent Running. The feeling continued as I entered the wilderness environments. Seeing the ocean, rainforest and desert areas. The quarters and kitchen areas reminded me that while things felt Sci-fi, they were in fact very science/reality based. In the... More

We went on a hot day, and nearly all of the tour is indoors. There were only six of us on the tour which was nice because there are some tighter spots that may make it harder to hear the guide. Our guide clearly had a lot of knowledge about the building, and past and current research. The engineering feat... More

We had a great time. ... The tour last 2 hours walking the facilities. ... Bring water. ... It's very informative but not for me I guess. ... A very expensive building. ...its about Gardening, hydroponics, and aquaphonics and etc. ... sustainable food from the garden in space is also interesting part. ... There is a small cafe but is...

A great place to learn about how our world works, and how we may be able to take our knowledge to other worlds. Our tour guide told us about the history of the biosphere and how it may be used in the future, now that Arizona University is running it. To do the tour you need to be reasonable fit.... More
