Experience Biosphere 2


The University of Arizona Biosphere 2 welcomes all visitors and strives to make its tours, exhibitions, programs, and services accessible to everyone. While much of the Biosphere 2 campus is wheelchair accessible, certain areas of the property are not accessible due the steep terrain as well as the presence of stairs on the under-the-glass guided tour. The under-the-glass guided tour of the biomes themselves is not accessible for individuals that use wheelchairs or walkers, or that have trouble navigating slopes and stairs.   Biosphere 2 provides a modified under-the-glass tour for guests with disabilities upon request.  For guests who are unable to visit the parts of the property that are not accessible, there are videos and descriptions available in our visitor center. We are often able to accommodate same-day requests for accessible tours, however, with advance notice of 5 or more calendar days we can guarantee the accessible tour will be available. To inquire about scheduling a tour, fees, or for other questions, please contact Biosphere 2’s group tour office at 520.838.6192 between the hours of 9 am to 5 pm Monday through Friday.

For those wishing to request a Sign Language interpreter, please fill out a request at http://drc.arizona.edu/about/request-interpreter or contact the University of Arizona DRC at 520.621.3268 V/TTY. This service must be requested prior to the visit.
