My family had a great time. I brought my 4 year old and she is pretty calm. I bough get a new camera which kept her busy. I wished I would have bought her a small handheld fan to keep her cool. We went early morning in June. It was very humid. The tour was 45 minutes inside and they did not have a bathroom in there. Once you are done they have restroom areas. I had to explain things in her terms but she loved it. Really learned a lot.

It was an interesting tour but felt rushed through the different environmental areas but then the technical part of the tour underneath the biosphere seemed to drag on. Definitely need water (they sell bottles for $2) and remember they close at 4.

It's more of an educational trip to learn about the research completed there. A lot of walking involved and definitely bring a bottle of water along!

We found it pretty boring, informative but boring and we are in our late 30's. If you do go, go when it's cool out not in the summer!

You get to experience how it feels like in a tropical forest. It's probably a better idea to go there during the winter if you don't like walking under the sun for almost 2 hours.

From Our Editors

In 1984, Space Biospheres Ventures purchased a few unassuming acres north of Tucson in the shadow the Santa Catalina Mountains. There, the company expanded its sci-fi-sounding activities—the development of space-colonization technology—and built what would evolve into Biosphere 2, recently seen on The Today Show.

Designed to re-create Earth's ecosystems, the gigantic glass enclosure (some 7.2 million cubic feet and 91 feet tall in some parts) is famous for housing biospherians in the 1990s. The researchers lived completely sealed inside for extended periods, giving scientists groundbreaking data on human survivability and interaction with particular bionetworks.

The University of Arizona had the 40-acre Biosphere 2 campus donated in 2011, maintaining it as a hub of serious research while expanding its mission to encompass interactive educational outreach. Each year, thousands pass through the on-site labs and classrooms as well as stroll the Biosphere 2 interior to view films, experience multimedia exhibits, or embark on guided tours. Tours venture into the actual ecosystems, allowing earthlings to note biodiversity, smell fresh precipitation in the rain forest, and savor the softness of savannah grassland underfoot until the resident grumpy old man yells at you to get the heck off his lawn. Before their dramatic conclusion at a million-gallon ocean tank, tours delve into the basement to explore the technosphere, where visitors can witness the deep inhales and exhales of the sphere’s respiratory system.
