There are a handful of ways to visit the Manhattan Project sites. 

Manhattan Project Sites in Downtown Los Alamos

Tour the town today and walk in the footsteps of J. Robert Oppenheimer, the Laboratory's first Director, and Nobel Prize winners like Enrico Fermi, Emilo Segrè, and Richard Feyman. Discover where Manhattan Project staff lived and worked and learn the story of Los Alamos, the "secret city on the hill.”

In downtown Los Alamos, the Manhattan Project National Historical Park experience is a partnership between the Department of Energy, the National Park Service, Los Alamos County, the Los Alamos Historical Society, and private landowners.

Manhattan Project Sites on Laboratory Land

These sites represent the world-changing history of the Manhattan Project at Los Alamos. Their preservation and interpretation will show visitors the scientific, social, political, and cultural stories of the men and women who ushered in the atomic age.

Though the park was established in December 2015, full implementation will take time. At Los Alamos National Laboratory, the Department of Energy is developing phased access to its properties in step with performing its ongoing mission. At this current time, Pajarito Laboratory (Technical Area 18) is open to the public twice per calendar year. These “behind-the-fence tours” are timed to coincide with the Trinity Site Open House at White Sands Missile Range. Registration is limited and is managed on a first come, first served basis for the first 100 individuals.
