Bio Sphere way cool

It was an eye opening display of what you could expect if you lived in a bubble for a long long long long time!

We were super excited to come check this place out. We were a bit early for our tour so we watched the short film in the main building. We then walked down to where the tour begins. Ummmm, they showed us the same video. We then were off on the tour with about 40 of our closest friends. Thankfully our... More

For the average tourist, this is an amazing place... however if you are "into" biology or life sciences then this place will blow your socks off. The builder's vision and the initial "mission" are staggering. Yes it has changed from a closed system to an open system (admitting, welcoming visitors) and that has changed the nature of the work and... More

Don't be swayed by others' negative remarks. I really enjoyed our tour and our tour guide, Brian, was great! My eight year-old got a tad bored, but overall we both learned a lot and appreciate being able to learn all that we did.

Very nice guided tour. Learned a lot about the history of the Biosphere, current research going on, and plans for the future. Not an exciting attraction, but if you are a enjoy science and nature, you will love it. Be prepared for a good amount of walking and a long uphill walk out in the sun at the end. There... More

Our tour guide, Mark, was extremely knowledgeable and enthusiastic. We will definitely be back and will bring our grandchildren to experience this science sphere. It was encouraging to see the young students here today as they are the future.

Don't pay attention to the negative reviews. I Went with my 17 year old son, and we both found the tour FASCINATING. One of the Bass brothers has contributed $500 Million to build and maintain this unique indoor multi-ecosystem facility, previously run by Columbia University (Ivy League) and now since 2007 the venerable research institution University of Arizona.

We went a number of years ago and was Luke warm on the tour. We went again this year and enjoyed it so much based on the knowledge and enthusiasm of guide. As we are about 8?years older now, found the numbers of stairs a bit more challenging. It has now been taken over by Univ of Arizona which has... More

The whole concept and history of the site is very interesting, but our tour guide lack any sort of enthusiasm or group skills. Glad I went, but would not go back.

I will keep this short. This place has no real purpose. I happened to visit this place because we were travelling as a group of 4 families and one of our family members had bought a groupon to visit this place. Nevertheless, the staff was extremely courteous but not very knowledgeable. The name is very fancy but it's unbelievable on... More
