There's only one Biosphere 2! Experience Biosphere 2 and find out for yourself why Time Life Books named it “One of the 50 must-see wonders of the world!” Visitors from around the world journey here to explore Earth's largest living research center studying the environment and the future of our planet.

Knowledgeable tour guides take you on this adventure and present the history, current programs, research and unprecedented vision using this engineering marvel. Also, don't miss our feature films, multimedia displays, bookstore and cafe.
