This is really outdated. But fun to look back at what it all started out to be. 


The Biosphere 2 Center is a great place to visit, especially if you have an interest in our environment. Here you can explore how man's actions affect the world. This center is the western campus of Columbia University's Earth Institute. The Biosphere's mission is to serve as a center for teaching, learning, and research about the Earth and its systems.

The Biosphere 2 Center is located on a 250-acre piece of land in the foothills of the Catalina Mountains. The main structure on the property is large and beautiful. It looks like something from the future, with its glass windows surrounding the entire structure. It is the focal point of the grounds. This structure is used for experiments related to our environment. Once you arrive at the Center, you will have some choices to make on how you are going to spend your day. You will definitely want to participate in a tour of the Center. 

Tour presentations are every 60 minutes. The tour includes a mile-long trail through the Biosphere 2 Center. Along the trail, there are knowledgeable guides to describe what you are seeing and answer questions. During the tour, you will see a mini-biosphere, the Test Module, and an Underwater Viewing Gallery. The tour concludes at the 3.15-acre Biosphere 2 structure. This structure cost $200 million to build. 

You will also want to take in the exhibits, films, and interpreters all of which will help you learn more about the goals and visions of the Biosphere. You will be intellectually stimulated. Another spot you won't want to miss is the setting. Outside the Biosphere you will see the Sonoran Desert in its beauty. If you are a birdwatcher, you will enjoy this area. The Canada Del Oro Restaurant is a great place to sit down and eat a meal. The restaurant offers breakfast, lunch, and dinner. From the Canada Del Oro, you look out on spectacular views of the Catalina Mountains. Reservations are requested; you can call 520-896-6220 to make your plans. There are three gift shops on the property. Each gift shop is based on a theme. The Desert Digs, the Rainforest, and the Coral Reef gift shops have interesting items for you to purchase to remember your visit.
