Biosphere 2

Great experience!!!! Learned so much about the history and research and love that it's still being used for research today. We opted to book the optional/additional lung and library tours and glad we did! Got to see really cool features and functions in person which was way better than just reading about them :) very clean all throughout and knowledgeable/friendly staff. Wish we could eat the fruit that was growing inside!

I'm from Tucson and hadn't been to Biosphere 2 until recently; I've officially found a new favorite place to take family when in town. The campus is beautiful and features a self-guided walking tour. I took about an hour and fifteen minutes to walk through start to finish and listen to some of the tour, which according to their website is exactly how long they expect people to visit. And while I didn't use it, there is also an accessible route to the different areas. My visit was kind of impromptu, and I went wearing ballet flats and a sundress. While I wouldn't recommend this, you can take the tour at your own pace so this was not an issue. In addition to good shoes, I would make sure you're well equipped with water and sunscreen. A lot of the tour is outside and you're subject to our Sonoran desert. If you like The Martian, The 100, or Lost, look no further - Biosphere 2 feel like you've been immersed into an unreal science fiction fantasy.

This is truly such a unique and must try experience. I'm in awe to this day of what I've seen here and learned. It's a fairly easy experience to have, plenty of accessible spaces. The story and education behind it all is really impressive, it continues to be a work in progress of new and old projects coming through. I'm excited by the development. The views and feel of the spaces themselves are really so great, it's hard to explain how unique it is to travel through the Biosphere. A heads up to download the app entirely before and/or there before walking if you'd like to have the audio and videos available for viewing during the walk around.

Biosphere has been on my list of places to check out for a while now. We had family visiting from Texas and they wanted to go, so this was the perfect opportunity. Overall, it's 4 stars for me simply due to the experience of that day. The weather wasn't great. Not biospheres fault. Just nature. And, actually I'm glad it was pouring rain, we always need more moisture is AZ. It just made for a wet and cold day walking around the property. The tour takes about 60-90 minutes. Self guided tour requires you to download the app. Cell signal is not good out there, they have wifi in the building. The tour is half inside and half outside. They have different areas you can visit such as the LEO (landscape evolution observatory), mangrove, ocean, desert, and rainforest. I can imagine on a nice day, it's great to walk around outside. The area I enjoyed most was the desert since it's not like our desert here in AZ, it's more the type of desert region found in Baja Mexico. It was lush, green, with flowers. The ocean area is neat too. The rainforest was cool, but a bit of let down, you can walk in and look at it, but can't walk through it. Open for Tours Monday-Sunday 9am-4pmAdult $27, Senior $25, Child (5-17) $15Closed Thanksgiving and Christmas DayWe went on a Friday and there were plenty of people visiting but didn't feel crowded.

This is a very interesting and fun place. I came here with my husband on a Sunday and we made it just in time to do the self tour before they closed. We arrived at 3pm and they close at 4pm but try to have everyone out no later than 4:30pm. The self tour with listening to each audio video took us about 70 minutes. Keep in mind there are multiple times you need to go up and down stairs. This isn't a problem for us, but if you're slower moving then the tour may take you longer. Make sure to download the app prior to arrival so that you are ready to go with the self tour. Please remember to bring headphones. There were so many people without them and they were listening to the audio out loud and it was very distracting when I was trying to listen to mine on my headphones. The fact that there is an ocean and a rainforest in the middle of the desert is just mind blowing. This is definitely a great place to visit and I want to come back to do the lung tour.

Visiting Tucson for the day so we decided to stop by the biosphere on our way down from Scottsdale. We are so happy that we did so! It's honestly a really fun experience. The price is very fair and it is a self-guided tour. They do offer guided tours as well, however, we chose to do the self-guided. You download an app, and at each stop (about 115 of them) the app tells you more about each location. You start outside to get views of the exterior and then you move into the desert dome, after that you head into the ocean dome and end in the jungle dome. You can make it a quick stop or spend as much time as you'd like.It's open from 9am to 4pm and there is no set arrival time. The last tours are allowed in at 3:30pm so it's a really freeform type of experience. I would highly recommend to anyone.

Everyone should see the Biosphere2. Interesting human experiment as well as environmental effort.

Super cool experience! My husband and I went to the Biosphere on a Sunday and had no issue getting tickets. It is recommended you purchase tickets in advance, as they only have 40 slots available per every 30 min. It's nice because you can see how many slots are available when you book - that way you know ahead of time how many others will be going through at the same time. The tour itself is very organized. They have an app for it that you can download either beforehand or on their wifi if you choose. We brought earbuds as to not disturb other groups or have to weed through which audio we were listening to. There was a fairly big group in front of us using a single phone on full volume, so I was happy we had the earbuds. The employees walk you through how to use the tour as well before you set out. It is *mostly* handicap accessible - the group in front of us had someone in a wheelchair, and we overheard that their lift is currently out of order (Aug 2022). Unfortunately, they aren't able to see the living quarters or the lower level. The rest of the tour, there are both ramps and steps available. The tour is approximately 1 mile in total, so be prepared for that! It is also mostly outside. We really enjoyed learning about the Biosphere experience and all the research that is being conducted there. I would highly recommend checking this out, especially if you're a science nerd like me :)

Absolutely a wonderful place to visit. Enjoyed the rain Forrest, the ocean was interesting, just a reminder to definitely wear comfortable shoes.....

What a surreal experience! Felt like I was in the ISS!! What a most interesting time and enjoyable, peaceful day. Just amazing what Man can do!!! Even bought a fee things at their gift shop!!
