Biosphere 2, Oracle

Our first visit was back in February 2019 just before the pandemic shut everything down. We had an amazing tour guide who took us throughout the entire facility including the underneath part. Our second visit in January 2022 was a little different, we had to download an app to download tour guide videos, and didn't have access to go underneath the facility like our first visit. Regardless, it was a wonderful experience and my mother who joined us on our second visit enjoyed it.

What a unique and fascinating site to visit! I would highly recommend it to anyone interested in biology or space exploration. Using a QR code presented at the front desk my group was able to take a video tour of the facility. It was so interesting to see the living quarters and notes of participants in the self sustaining facility Biosphere 2 experiment along with the beauty and design of each of the artificial environments. With a gorgeous view of the mountains, sculptures, beautiful landscaping, and donated minerals and fossilized wood in between each stop in the tour there was never a dull moment.

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.

I have been wanting to visit here since my niece told me all about the Biosphere. I live in MA and was looking forward to our visit. Thankfully they said we visited at a slow time. They expect to be very busy in the next month or two and recommend buying tickets in advance. We were able to add on the private tour last minute to see "the lung." We really enjoyed our entire experience here and found it very informative. Who knew that the Biosphere 2 was 20 times more airtight than a space ship!!

My wife and I had a great time here. With a gorgeous scenery, that makes for some great photos. I also enjoyed there user friendly app. Which takes you step by step and with great insight on what the scientist went through and their goals. Best time to go would be the cooler months. There is walking and the rainforest section is SUPER humid.
