Start with our Visitor CenterDrop by our visitor center to start your Manhattan Project National Historical Park experience in Los Alamos, New Mexico. Speak with park rangers, watch a short film on the Manhattan Project, pick up a junior ranger book, and get information on Manhattan Project sites throughout the community. Don't forget to stamp your passport book with our traditional passport stamp and one-third of our unique three-part stamp. The Hanford, Los Alamos and Oak Ridge visitor centers each have one third of the stamp. Plan ahead for your visit by downloading the National Park Service App.
