April is Earth Month at Biosphere 2!
Join us each Saturday in April for a month-long exploration of Planet Earth. And don’t forget to come celebrate Earth Day on Sunday, April 22!
In addition to Biosphere 2’s three new themed tours, Saturdays in April will feature special beach tours with ocean critter releases, Biospherian book signings, and hands-on earth science activities for the whole family.
