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. Biosphere 2's ADA-tour was featured in LivAbility.  If you have any questions, please email us at or call our admissions team at 520-621-4800.
