Ride with GPS map.
This ride takes in the Biosphere 2, the world's largest controlled environment dedicated to understanding the impacts of climate change. Biosphere 2 is now run by the University of Arizona.
Self-guided 75 minutes tours are available for $25 but you will need to lock your bike outside as we were unable to secure indoor storage. The gift shop has light snacks.
