  • So i took my wife here for her first time, mine was back in 1995.July 2nd on a friday, awesome not crowded, and great hot weather, which we love. Pretty much the same since 1995, except i dont recall ...  more »
  • A detailed tour with a very knowledgeable guide took about 1.45 hours. We found so much information on the experiments passed and present, very detailed videos and story boards, to look at yourself, t...  more »
  • It's worth the drive to Oracle to see this amazing facility. It began as a privately funded experiment in 1991 and is now an environmental research station of the University of Arizona. Take a guided ...  more »
  • What an awesome educational experience! To think that 8 people agreed to being literally locked into this grand experiment for 2 years is amazing. The guided tour is exceptional! Highly recommend
  • Biosphere 2 presented me with a beautiful and ingenious look at how the biosphere acts, but in a much smaller scale that is controllable. Everything about it is interesting and is explained, from how it came about to how it works and problems encountered. It was a very educational trip and I would definitely recommend going to anyone interested.
  • This was an amazing undertaking at the time it was built and while that is a great story, what the University of Arizona has done here since taking over has been fantastic! A lot more "science" is going on now and yet, still coinciding with caring for Biosphere 1, our planet! Very good tour guide and loved the "lungs" of the facility. Word of the wise, it is a tropical jungle inside, don't wear a coat! There are many steps up and down. They do warn you about it but some people really struggled. There just isn't room for ramps or elevators. That said, we didn't find it hard, but we have no physical ailments. Lovely gift shop, clean restrooms and a nice cafe add to the enjoyment.
  • While Biosphere 2 is primarily a research facility, it has been opened to the public as an educational facility and museum. Younger children may not enjoy the information heavy tour through the facility, but anyone with a minimal level of scientific knowledge will be greatly benefited from the information they gain during the tour. The tour experience varies based off of the experience of your tour director, but all guides will have their own experience with the Biosphere. I highly recommended visiting Biosphere 2 if you have any amount of interest in environmental sciences.
  • The Biosphere 2, a scientific masterpiece from the 80's, is by far one of the most interesting places you can visit in Tucson, Arizona. From the history of the experiments attempting to recreate life in a glass dome to the more modern tests being run today - the biosphere has an entire era of environmental research beneath its 6500 windows. Beyond the sheer size and ingenuity of the setup, the biosphere 2 and the struggles it has faced over time, give you a deeper insight into and appreciation for the wonders of the first biosphere: our earth.
