Interesting place to visit. Focused on the scientific experiment and not the social experiment.

Be sure to wear good walking shoes. There are as many stairs as they say on the website! No bathrooms during the tour. Everything was pretty much explained ahead of time and we appreciated that.

It is a ways off the interstate and you need to plan for that. It was extremely interesting and the docent was extremely well informed.

Lots of walking, most can be done on ramps to avoid the stairs but you need to plan on it. It is an education. Remember that this entire project is a scientific experiment - but one worth sharing for sure! Take water!

Wear comfortable shoes. A fair number of stairs. Definitely worth going! We had a blast and learned so much. Tour was informative and hit the high points. Then we took a couple of hours and explored on our own. My friend got a sandwich in the Cafe and he said it was good.

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.

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.
