A visit to Manhattan Project National Historical Park will be different from a visit to many other national parks. The park operates in three distinct communities that share the stories of the Manhattan Project: Hanford, Washington; Los Alamos, New Mexico; and Oak Ridge, Tennessee.
As you plan a visit to the park, the pages below can help you. Some facilities related to the park exist in restricted areas. Members of the public may not be able to see certain places, or may only access them through organized, guided tours.
