Biosphere 2

Located across a 3-acre research facility, Biosphere 2 (B2) recreates five of earth's biomes--the ocean, wetlands, tropical rainforest, Savanna grassland, and fog desert--enclosed under glass domes. Included in your admission is access to the Under the Glass guided tour of Biosphere 2, which is offered throughout the day on a first-come, first-serve basis. Guests on the tour will get to experience the Biosphere as they wander through the rainforest, walk across the ocean overlook, explore the coastal fog desert, and travel through the underground technosphere, descending into one of the amazing "lungs" - an engineering marvel - that helped moderate air pressure in the sealed B2 environment.
