Start with our Visitor Center in Los Alamos

 

In Los Alamos, New Mexico, Manhattan Project administrators found an ideal location for the secret laboratory where they designed and built the world’s first atomic weapons. Isolated on top of a mesa, with canyons cutting through the surrounding landscape, this place provided the remoteness they required. Still, Santa Fe was relatively close, giving them access to transportation and other resources.

Drop by our visitor center to start your Manhattan Project National Historical Park experience in Los Alamos. Speak with park rangers, stamp your passport book, pick up a junior ranger book, and learn about ranger programs.
