“A most interesting place”
Reviewed November 26, 2013

It has been years since it had occupants but a great deal of good research came out of here. The planning and architecture are rather amazing in and of itself. Half of the admission fee is tax deductible.

“Unexpectedly interesting and informative”
Reviewed November 17, 2013

We had a good time here for a couple hours of interesting facts and stories about this amazing structure and institution. The tour guide was very knowledgeable and passionate about what she is trying to share with us. The architecture and the engineering marvels alone is worthwhile to visit this attraction, but the scientific information you will learn from there is for sure not to be missed.

“Learn a lot while having fun”
Reviewed November 17, 2013 via mobile

Spent the day seeing how to live in an enclosed environment. Saw five different temperature regions all under one roof. Learned how eight people survived for two years.

“Interesting & educational”
Reviewed November 9, 2013

This place is fascinating - there is lots to see at your own pace, plus guided tours. You don't need to be a science geek to enjoy the tour. Entry is $20, a bit on the high side but half of the cost supports Biosphere 2 research. The facility supports enclosed tropical, marine, marsh, and desert ecosystems, among others. You can see the ecosystems, facility architecture & infrastructure (which is amazing when you think of the engineering involved), and the housing where the biosphere team lived for two years. Our tour guide was so-so, but you can tell from other reviews that this is variable. The tour was enough to insight your interest to learn more about Biosphere. The tour spends quite a bit of time on the experience of living in the biosphere, and I would be more interested in results of past and present research and engineering that has the goals of developing sustainable man-made environments and learning about earth ecosystems. There are plenty of bathrooms, but neither the facility nor the tour are designed for handicapped accessibility. There is a limited selection of (good) pre-made sandwiches and salads, and there are good pizza/Italian restaurants in nearby Oracle.

“Gave me the feeling of being in a giant space ship”
Reviewed November 1, 2013

I was lucky enough to get the special tour with Taber McCallum himself as guide (one of the original 1st crew) and saw a lot of extra and behind the scenes stuff. Nevertheless I would recommend going here as it is a very interesting place to walk through. It gave me the feeling that I was in a giant space ship as portrayed in some SF movies, where generations of space travellers live and grow their own food, create their own recreational parks. As Biosphere 2 did try to research what life would be like on another planet (like Mars) living under a dome, creating a home away from home my observation is probably not completely off the mark.
If you are in the neighbourhood I would recommend you make arrangements to do a tour here as it is interesting for all ages.
It is an easy drive (45 minutes) from the center of Tuscon, taking the Arizona Highway 77 north for 24 miles (36 kms). No special vehicles (SUV) needed to get there. There is a cafeteria on site and a souvenir shop. Biosphere 2 is open for tours daily 9am-4pm. Closed Thanksgiving and Christmas day. No reservations required.
There is a fair amount of walking up and down stairs, plan for that.
