This could best be described as faded. The main exhibit of the 1990s is basically gone with only remnants found in an unkept facility. The tour was uninspiring and the rust and wear was obvious. You kept waiting for something interesting that never happened. The glass looking into the saltwater pool was so caked with the algae you couldn't see... More

The biosphere 2 buildings look odd and one of a kind. The guided tour lasts about an hour with introduction, history, and current usage/learning of this facility. Overall the visit is very interesting and suitable even for non-scientific people and kids. Although there was a negative publicity in the 90's of the failed experiments, it is indeed a nice piece...

Enjoyed our guided tour of the Biosphere 2 with Orville. You are assigned a tour upon arrival and have time to visit some exhibits prior to your tour. Plenty of informative stories on the tour - seemed to be a good balance for my husband and I

When staying in Tucson area, my husband and I decided to check the Biosphere 2 out. The first tour takes about 45 min. and it is mostly about technical information. I believe this tour in free and everyone can attend. Then you moved into the second tour (which we had to pay for) that lasted for about 1 hr.15 min.,... More

My husband and I were looking for something to do on a cold, windy day in January and decided to give this a try. We had about a 50-minute wait for the next tour after arriving, so we had sandwich in the little café and then browsed some of the exhibits. The tour starts with a short film that provides... More

The Biosphere 2 has been a long standing destination for visitors to the Tucson area. The interest is in the learning curve that scientists have gone through in their attempts to create a self sustaining controlled environment. Great learning for all ages, if you overlook the aging technology but enjoy the scientific journey.

We arrived at Biosphere 2 just in time for the 11 AM tour, which lasted about an hour and a half. After the tour, we had lunch in our RV and came back in to "self-tour" the rest of Biosphere 2. The information is well-laid out and you can find out in depth information about SO many things! Solar power,... More

Uplifted our group's mood that was depressed from a mine tour earlier today. Something for everyone and all ages!

My husband and I truly enjoyed getting to walk through Biosphere 2. Not only are the exhibits neat, but the history behind the place is definitely worth reading about before visiting. It adds a whole new element while walking through!

This is just not worth it. It's really pricey to get in. The technology is old. It was a very expensive failed experiment from the '90's. I'm not sure that they really gathered any real knowledge here. Just a big waste of money. I do not recommend this as an attraction. Don't waste your time.
