We welcome visitors with Service Animals, and you don't need to notify us in advance if you're visiting with a Service Animal. Animals whose sole function is to provide comfort or emotional support do not qualify as Service Animals under the Americans with Disabilities Act (ADA) and are, therefore, not permitted without prior approval.

The University of Arizona Biosphere 2 welcomes all visitors and strives to make its tours, exhibits and programs 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 and the presence of stairs. The majority of the biomes including the desert, savanna, ocean and rain forest are all accessible by wheelchair or scooter. Our team will work with you to help access the areas open to the public. If you have any questions, please email us at BIO2-INFO@ARIZONA.EDU or call our admissions team at 520-621-4800.
