Trinity Site

Restricted Jornada del Muerto test site where the first atomic bomb was detonated in 1945.

Trinity Site is one of the most sobering places in New Mexico, though it is not a casual stop. The first atomic bomb was detonated here in July 1945, deep in the desert of the Jornada del Muerto, and public access is usually limited to occasional open-house days.

If your timing works, the visit is stark rather than scenic: a fenced ground zero, desert silence, and a history that still feels uncomfortably close. Check official access rules before planning around it.
