We made a day trip from Scottsdale based on a friend's recommendation. The tour lasted almost 2 hours and our guide was very helpful and knowledgeable. There were several other exhibits to go through on your own. It was all very interesting and a great way to spend a day doing something a little different. Led to great discussions on... More

Our visit to Biosphere2 was worth the 2.5-hour drive from Scottsdale. Very interesting tour with great exercise walking up several flights of stairs. Its an educational tour filled with great commentary from the tour guide. Younger children may not be as interested in the tour as adults. Even the snack we purchased at the cafe was a good experience. The... More

I am very glad we got a chance to see Biosphere 2 despite the fact that the 3 1/2 hours we were there was way too long for us. We got there about a half hour before the tours began, and planned to do the history as well as the general tour. I was very interested In it's history and... More

We visited and toke the tour (which you must do to visit) and thought it well done. It's informative to hear the Mission and history. It took about 90 minutes. You then have some time to wonder about. It's a striking structure.

This was an interesting experimental project and is still used for continuing research. The docents are helpful and knowledgeable explaining how this experiment was conducted.The "lung" was amazing. The people working at the Biosphere were all accommodating and helpful. The tamales at the Cafe were quite good. We enjoyed this activity and found it worth the drive to Oracle.

I am visiting Arizona on vacation from Mass. I was looking for fun things to do and this popped up. What an amazing experience. My friend and I arrived wednesday afternoon around 12:45, walked to the main building and bought our tickets. (Discounts for students! Bring your student ID) Totally worth the $20 per person. It is about an 8-10... More

one time a year, there is a week that you are allowed to walk freely (between x-mas and new year) and this year we were so lucky to have this. Amazing place and you can totally feel the way people lived here for such a while. Great scientists!
