I have been to the Biosphere 2 twice - once in 1998 and in 2002. This week, my husband and I were staying locally and decided to visit. For him, it was a first time experience. We downloaded the app prior to driving, as well as purchased tickets in advance. $24/senior. As we drove, we listened to a podcast with two original Bioispherians, as well as three short audio lessons about Tucson and the history of the area - all done quite well. When we arrived at the Biosphere 2, we used our phones to listen to the 19 stations located throughout and around the Biosphere.
Things were changed due to Covid. There used to be docents taking you around the Biosphere, but now there is the audio app which also includes pictures. You move through the Biosphere and around on the outside. There are several docents to answer questions. Since U of A took this facility over, things have really been upgraded and well maintained. The audio tour of the 19 stations was excellent but it didn't take you to all of the places I remembered going to 20 years ago. I remember getting to see the LUNGS of the Biosphere as well as a COMMAND center of some sort, but apparently, these are separate docent led tours at an additonal cost. We are so happy we took the tour of the Biosphere and plan to return for the addtional tours at a future date.

I’m all about education and I don’t mind paying for a great educational experience; however, we did find this interesting but not worth the entry fee. I’m sure Covid has changed the viewing experience. You download the app and hopefully you have brought headphones so those around you don’t have to listen to the stops in stereo. The app has lots of additional in-depth information, but you will have lots of questions after your visit. So, dig back into the app.

The whole concept is very interesting and the project was probably way ahead of its time. As you journey through the facility, they keep telling you what they have planned for the “future”. It’s pretty obvious that they have let much of the facility projects deteriorate. Hopefully, in the “future” this will be a bit more interesting with scientists conducting onsite studies.

Three Stars: here is why we gave this a three star rating: nothing to keep children engaged! A family of four would pay $80 for admittance and it’s just a walking tour right now. No hands on, no watching the scientists do any experiments, nothing at all to engage a child’s imagination or mind. The videos on the app are ok, but not for kids. As for a value for the visit, we felt this was way below the price we paid.

It'll be about 1 1/2 hour drive from Mesa to get to the Biosphere 2 but well worth the drive. Cost of admission is very reasonable, we just did the basic tour which I feel was more than adequate. The guide was very knowledgeable and the the tour takes you through every part of the facility, with the exception of the rain forest. As it is currently closed for a research project. I would definitely go back here in the future to check this out once that part of the facility was back open again. Something that is not part of the tour but I would recommend checking out is located on the east side of the biosphere is access to view below the "ocean". There are exhibits in here and glass where you are able to view what is going on under the surface of the "ocean" area. I'd recommend this tour for adults only, as there would be nothing of interest to children on it.

Very disappointed in our “tour”. You are told to download an app and watch 18 videos as you walk the complex. While we did go in part of one of the buildings there was so little information given about the experiments that have been run and nothing communicated about what was learned from the past participants groups. There was no science at all. Very disappointed as I was hoping this would be a great learning experience for my kid but it was not at all. While I understand we are in Covid right now for the high cost of admission I would expect to be able to converse with someone about the science behind Biosphere. Very disappointed.

$25 for a less than 60 minute walking tour guided by a pre-downloaded app. It appears to be a facility that’s still trying to be relevant when in fact it never really was. I find it hard to recommend both from an interest perspective and a value for money perspective. Best to miss.

This place is certainly a rare and unique place to visit. How could we not take our 9 year old daughter?!! She was a little bored walking around outside, looking at building and listening to virtual tour guides. Once we finally got to go inside, she perked up a little. We were very interested in the opportunity to share this educational experience with her but we had to do most of the exploration. We did get to ask questions with a volunteer near the end of the tour and that was nice. I can imagine the tour is much better with a live tour guide. It would have been nice to see the living quarters. I’d recommend you visit even if the tours are still virtual because it will spark questions and imagination.

Biosphere 2 was an awesome experience! It had great tour guides who were extremely knowledgeable and fascinating exhibits. Definitely make sure you book ahead of time and get there early to make sure that you get to see everything you’d like to. There is a cafe but bring your own water, because it’s pricey and they have fountains around where you can refill your own bottle. It isn’t far from Tucson—a must-see if you’ll be in the area.

This is a good experience and I learned about on going studies about our earth habits. We took the Modified Tour for the handicapped. We walked a mile with a lot of breaks. Modified tours are at 11:00, 1:00 and 3:00 pm. Regular admission is $21 and Seniors is $19. The modified tour guide uses a portable speaker so everyone heard well. Return trip was by golf cart if you want. Beat the crowd and go on Tuesday- Thursday was recommended. The University of Arizona runs the program and is very professional. Enjoy

The Biosphere2 has an interesting history but with the self guided tour and trying to use their app, it was disappointing. I’ve been there before, when they used to give live tours. Now you use an app. WiFi was spotty, and you could tell you were missing a lot buy how you walked past a number of items where the app had nothing for you.

This place looks cool from a distance but that’s about it. It’s completely fallen into disrepair—cracked windows, rusted, dying plants. At a minimum, the entire place needs cleaning. From a learning experience it is poor. The informational signage needs to be overhauled. They could do video at the beginning of the tour so visitors understand the history. An adult ticket is $25. I suggest skipping this place and going to Pima Air and Space which is only $18.
