Public tours of the Manhattan Project National Historical Park in Los Alamos will take place on March 29 and 30. Tour registration will begin Feb. 15 at noon MST.
Each day will have two tours with 25 people each, and registration for the free tours fills up quickly.
On Los Alamos National Laboratory property, participants will see and learn about the original Pond Cabin, which served as an office for physicist Emilio Segrè’s Radioactivity Group; a battleship bunker that protected staff during explosives testing; and the site of Louis Slotin’s deadly criticality accident.

These “behind-the-fence” tours are hosted by the Laboratory in collaboration with the Los Alamos Field Office of the Department of Energy’s National Nuclear Security Administration and the National Park Service. As an active national security laboratory, Los Alamos National Laboratory has specific entry requirements for visitors. Details will be provided to registrants; compliance is necessary to avoid being turned away from the tour.
