It was great to see green in the desert. The amount of stairs and walk was little much for us though. Make sure you can walk quite a bit before starting.

The coral reef is dead. There are no animals. The structure is rusty paint peeling everywhere, The kiosks are all broken......none worked. The guide was rude. The roof was leaking rain in numerous places.....save your money and time......Very disappointed. TOTAL RIP OFF. I'll bet it was impressive when it was working.

The Biosphere 2 is a very interesting tour. They mention 100-150 steps - that is NOT all at once. It is just that the entire tour has steps here and there, more like 10-20 at a time. So little kids are perfectly fine during the tour also. They had about 15 people in our toured group. Part of the tour... More

Went here on a whim at the suggestion of my college-aged son and it was well-worth it. Probably best to visit either early in the day when it first opens or wait until November through April if you don't enjoy the heat. That being said, the tour was both educational and entertaining. Our tour guide, Ren, was terrific and informative.... More

During a trip to Arizona, this was one of my favorite stops. I never knew it existed until I was exploring and happened to read about it. I enjoyed exploring the various ecosystems. It is unfortunate that they were not able to continue this experiment because I believe it would be worthwhile. Great place for children, but try to come... More

It was very hot the day I went (108). The walk is daunting but I really enjoyed it and would do it again just not while it's in the 3 digits! There are several sections in the Biosphere like the ocean, desert and rain forest. I was a little disappointed that we didn't walk through the rain forest but I... More

We have all heard the story of the experiment now this walk thru of the facility is really interesting. It's a shame they don't have more money to keep it up better

My teenage son and I visited Biosphere 2 in late June, and really enjoyed our visit. Some tips to help during your visit: TIPS: 1. I had my son watch a 9 minute NY Times video (http://www.nytimes.com/video/booming/100000002268243/biosphere-2-an-american-space-odyssey.html) that I found on the Wikipedia entry for Biosphere 2. The video gave him some context on Biosphere 2 for our upcoming visit,... More

We were a bit apprehensive about driving up to this site as we thought that it might have been all advertising hype. We went in late June on a Friday at noon. The place was not busy as this is low season. We grabbed a tour ($20 each) and headed off with a guide for an hour and a half.... More

Where the Space station was born... There is the beginning of the scientific research for living in space as an autosuffisant society... Amazing...
