The guided tour is very informative and interesting, though the walk was much longer than I thought (you have to walk quite a ways, down many stairs to get to the starting point --THEN, of course, you have to walk back UP all those stairs after the tour is done). Complaining aside, it is a VERY INFORMATIVE and INTERESTING tour... More

Visited with my granddau who is college Sr in environmental conservation. She understood and loved the creation of an entire range of environment under glass that was self-sustaining. I enjoyed the tour as an educational experience well outside my usual scope of interest! Time well-spent!

this was a pretty interesting place to visit. this unit was built for scientist to live in for two years to see if we can visit a far away galaxy and have a dome to live in. epic fail as the scientist ordered pizza before the event was over! however it was filled in wonder as to how great it...

The introductory film is very good as was the person that welcomed the tour group. She was very informative and kept the group moving at a nice pace. There are a lot of stairs on this tour so if you have problems with stairs, this would not be for you. Very interesting although I think it is in need of... More

We did a short day trip from our home and was glad of the experience; but it wasn't a place we would visit again. As seniors, we appreciated the availability of water and restrooms. There were lots of stairs, but even so it was doable for my husband and myself. Took advantage of benches and chairs to rest during our... More

I am very interested in climate change , science and this experiment. However people in my group were bored. The tour begins with a movie, documentary style. People were yawning. Since this is no longer a closed system it was interesting to see cactus wrens nesting. Our guide was very informative and personally I enjoyed the tour a lot. Get... More

The Biosphere2 is a fantastic research facility that started out as a privately funded experiment on the possibility to create habitats on other planets, but now an environmental research centre for the University of Arizona. The size of this project is impressive. The tour is somewhat underwhelming, and I feel it could be better. Still, it was a great opportunity... More

Being something of a science nut I was looking forward to visiting this attraction. My first view of it certainly had a 'wow' factor. Tours are conducted on a regular basis and I was enthralled by the comprehensive history of the project outlined by the guide. I found the whole experience unforgettable; but then I'm something of a science nut.... More

This is a very cool massive science lab that includes 5 biomes under an enclosed dome. The tour will take you through the history of it's existence, what's happening there today and also lets you explore the apartments from when people lived there.If you have a budding scientist, he/she would probably love it. It's not your typical tourist attraction, definitely... More

Nice education, but overpriced in my opinion. Nice people and very informative, but maybe i am more of a physical sciences guy rather than life sciences. In retrospect, I would have passed on this tour knowing what I know now.
