Take a ride through history and learn all about the Manhattan Project on DOE's Public Bus Tour. Get a glimpse of life behind the fence in America's Secret City. You'll tour Y-12's New Hope Visitors Center, Bethel Valley Church, the Graphite Reactor at ORNL, the Spallation Neutron Source, and the former K-25 site.


Bus boards from the American Museum of Science and Energy at 11:15 am, leaves promptly at 11:30 am and returns at 2:30 pm. Guide commentary provided throughout tour. Participants must be citizens of the U.S. 10 years of age and older. Seating is limited and available on first-come, first-serve basis. Some restrictions do apply.
