This is a unique attraction! I had never heard of this experiment, so it was fascinating to learn about it! There is a lot of stairs [around 150 of them] and walking - so not such a good place for people who have problems with that.

The Biosphere 2 is an amazing attraction to visit! It was created to better understand how natural environments generate conditions appropriate for life. B2 is a unique research facility used to study ecosystem processes under controlled conditions. It has several buildings to explore, take a tour to find out all about the facilities for a better understanding of what actually goes on there. Great for all age groups. You'll be surprised! Wear a hat and comfortable walking shoes. B2 is open from 9 am to 4 pm every day, except Thanksgiving and Christmas and is located off Highway 77, approximately 30 min. north of Tucson. Discover a whole new world there - it's really amazing what they've done.

If you are in the area, this really is a must to visit. It is a part of modern history, imagine 8 people living in this secured facility for two years. Now, it is an incredible research facility. The architecture and infrastructure is very interesting. Our tour was about 2 1/2 hours, and took us through the biomes, the basement and the south lung (you need to visit to find out what this is!). Our only recommendation is that the number in the tour group should be limited to 15. Our group had about 30 which was much too large. Also, this is not a tour for small children, strollers are not feasible (given the stairs and small spaces). There was a toddler in our group, between his screams and running away, it was very distracting.

Well worth the visit. Very knowledgeable guides. Be prepared for the stairs and long walk to the entrance

Short drive from Tucson. The lung was amazing. All walking, quite a few stairs to climb, interesting facts about past research and future plans. Discount for AAA membership=$18 tour cost.
