Hanford: Tour Behind the Fence

Learn and Explore

During World War II, the top-secret Manhattan Project sites maintained high levels of security. That legacy continues today in Hanford. Nearly all of the park’s historic properties are located “behind the fence” on secure federal Department of Energy reservations. Public access is only permitted though public tours facilitated by the US Department of Energy.
