Biosphere 2 is located north of Tucson, Arizona at the base of the stunning Santa Catalina Mountains. This one-of-a-kind facility sits on a ridge at a cool elevation of nearly 4000 feet and is surrounded by a magnificent natural desert preserve. Come experience the remarkable Biosphere 2 which Time Life Books recently named one of the 50 must see "Wonders of the World". See why visitors from around the globe journey here for this unique adventure not found anywhere else. Discover real-time research on the future of our planet as it unfolds in the specially designed mini-world. Starting at the visitor center you will get a first look at our new exhibit "Phoenix Mars Lander" which landed on Mars in the summer of 2008.
The visitor center also houses numerous other exhibits and multi-media displays along with a Bookstore and Cafe. You won't want to miss our new feature movie showing in the main theater which describes the past, present and future of the project. Your entry into the Biosphere is led by a tour guide who takes you inside and under the glass. The beautiful trail system takes you on a once in a lifetime tour that lets you smell our ocean and see a tropical Rainforest up close. In addition to escorting you through the upper Biomes, your interpretive tour guide takes you through the basement “technosphere” and into the amazing lungs that help the Biosphere system breathe. Your tour will conclude in the custom-built underwater ocean viewing gallery where you can explore the million-gallon ocean and its real coral reef. Before or after your tour, take time to enjoy the many different programs or events that are offered throughout the season. Your experience will be like no other!
The admission desk at our visitor center will provide tour times and start locations. While some areas are wheelchair accessible, certain areas cannot accommodate non-ambulatory guests because of the steep terrain and presence of stairs through sections of the Under the Glass Tour. The Guided Tour of the biomes is not accessible for wheelchairs, walkers, or strollers. For areas not accessible there are video clips and descriptions in our visitor center. For hearing impaired visitors, the University of Arizona Disability Resource Center provides sign language interpreting services for tours of Biosphere 2. This service must be requested by the individual prior to the visit. To request this service, please contact the University of Arizona Disability Resource Center or 520.621.3268 V/TTY.
Group and School Tours can be arranged, which normally include a historical overview of the Biosphere 2 project, a look inside under the glass at many of the biological systems within the structure, and discussion of past and current research underway.
