Visit Hanford

Start with 2 Visitor Centers in the Tri-Cities

The Hanford Engineer Works produced plutonium at a roughly 600-square-mile (1554-square-km) site along the Columbia River in Washington state for the Manhattan Project during World War II. Workers at the Hanford Site constructed and operated the world’s first nuclear production reactors that produced the plutonium used in the Trinity Test and in the atomic bomb dropped on Nagasaki, Japan, on August 9, 1945. The Tri-Cities has two visitor centers where you can start your Manhattan Project National Historical Park experience: 

  • Hanford Visitor Center with Manhattan Project National Historical Park
  • Tri-Cities Visitor Center
