It's worth the drive to Oracle to see this amazing facility. It began as a privately funded experiment in 1991 and is now an environmental research station of the University of Arizona. Take a guided tour; adults $20, discounts for kids and seniors.

This is located in a rather remote location, but well worth the drive. We had an excellent tour guide who led us through the rain forest, ocean, and desert areas as well as the "lungs" which helps maintain the air pressure inside.

Orville was our guide and he was fantastic. It is a very long tour, up and down steps, but well worth it. My favorite part was actually in the basement; how the windows in the biosphere do not implode or explode. Fascinating!! I very highly...More

A lot of walking but well worth the day. Explore the Biosphere where a research team spent 2 years sealed inside. Now open to the public with lots of environmental and plant research still going on today.

You don't need reservations. I'm not sure if there is a price difference but if you are going, you need to take the tour to see most of the biosphere. Without the tour you will only see a fraction of the biosphere. It's a... More
