MAPR is not a traditional park, where visitors can drive through an entrance gate to begin exploring. Instead, you drive into our communities to see the park visitor centers, historic sites, museums, points of interest, and more. We work with community partners to provide a variety of places and experiences that collectively share the story of the Manhattan Project.

There are a few key ways to visit the Manhattan Project sites in Los Alamos:

  • Visit the National Park Service’s visitor center and get your passport stamp.
  • Join a guided walking tour of many MAPR sites with the Los Alamos Historical Society or print your own walking tour map
  • Tour the Bradbury Science Museum, which has replicas of Little Boy and Fat Man and exhibits about how the Manhattan Project informs science today.
  • Visit the downtown Los Alamos filming locations for Oppenheimer, Christopher Nolan’s upcoming biopic about J. Robert Oppenheimer.

    Downtown Los Alamos sites are managed through a partnership between the Department of Energy, National Park Service, Los Alamos County, Los Alamos Historical Society, and private landowners.

Laboratory sites represent the world-changing history of the Manhattan Project at Los Alamos, as well as the social, political, and cultural stories of the people who ushered in the atomic age.

Behind-the-fence, guided tours are only offered twice a year; they complement the Trinity Site open house dates. Spots are limited to the first 100 people on a first-come, first-served basis. Please note that tour spots fill up quickly.
