Step into a recreated tropical rainforest, complete with towering trees, lush vegetation, and a controlled climate. This biome offers an immersive glimpse into a fragile yet thriving ecosystem. Temperatures and humidity mimic authentic rainforest conditions, giving visitors a sensory-rich experience. Look for interactive kiosks explaining the importance of rainforests in regulating global weather patterns and producing oxygen.

A rare indoor ocean, complete with a coral reef system, makes this feature a standout. It demonstrates efforts to study marine biology and ocean acidification’s impact on coral ecosystems. Guests can observe researchers maintaining the habitat and learn about the challenges facing real-world ocean conservation. Audio stations throughout the exhibit share expert commentary for a deeper dive into the subject.

This area highlights Biosphere 2’s scientific facilities that once supported closed-system living experiments. Visitors can step into structures originally designed for self-sustained human living and discover ongoing experiments in water conservation and food production. Don’t miss the overview of how Biosphere 2 contributes to NASA’s exploration of sustainable habitats in space.

Biosphere 2 originally operated as a closed ecological experiment from 1991 to 1994.

It’s now managed by the University of Arizona as a public education space and research laboratory.

The facility spans over three football fields, making it one of the world’s largest controlled environments.

October through April for cooler weather.

Comfortable shoes, sunscreen, and water bottles.

From Tucson, take AZ-77 (Oracle Road) north for about 45 minutes.
