Our tour guide - Gabby - was excellent! We really enjoyed the tour and learning more about Biosphere. The walk, to us, was easy though I expect some might have a problem as there were multiple sets of steps to climb. We enjoyed visualizing ourselves...More

Took my 12 year old grandson, he enjoyed it as well. Educational and fun !!! There was a group from the nearby college with their professor, it is truly multigenerational. Not recommend for anyone that has trouble walking, steep and narrow walkways in some places.

This place is "different". It is historical, interesting, eclectic, campy, and beautiful. Pat its prime but well worth a cool day trip to Tucson just for the views and the history of the site. Café is really a premade snack shop...nothing fancy. Warning: we took...More

This is an excellent tour of a very unique facility. The history alone makes this a must-see site. But the ongoing work by the University of Arizona researchers in earth sciences, agriculture, and solar energy are fascinating. The 1 1/2 hour tour is very interesting...More
