Minidoka National Historic Site

Minidoka National Historic Site commemorates the Minidoka Relocation Center, one of the sites where Japanese Americans were incarcerated during World War II; it preserves and interprets the camp’s history and physical remains. The unit recognises the forced removal, detention and challenges faced by those incarcerated there between 1942 and 1945.

Visitors encounter exposed building foundations, a memorial cemetery and interpretive panels that describe camp life, administration and the broader wartime policies that produced the relocation program. The site focuses on education and commemoration rather than full structural reconstruction.

The camp was established in 1942 by the U.S. government as part of the wartime removal of Japanese Americans from the West Coast and remained in operation until 1945. During that period thousands of people were interned at Minidoka and associated facilities.

The historic site lies in south-central Idaho near the towns of Jerome and Rupert on the Snake River Plain and is administered by the National Park Service as a unit dedicated to interpretation and preservation.

• Scale and remains: Approximately 9,000 people were confined at the Minidoka Relocation Center during its operation; the site preserves foundations, a cemetery and interpretive exhibits that explain the history of Japanese American incarceration.

Minidoka is near Jerome in south-central Idaho, roughly 40-60 minutes from Twin Falls by car. The site is best reached by private vehicle; there is limited public transit in the region. From Twin Falls, take US-93 south and local roads toward Rupert/Jerome and follow signs to the historic site.

• Check seasonal opening times for visitor centers and any ranger-led programs-some events occur only in summer.
• Combine a visit with nearby historic sites and recreational paths along the Snake River for broader context.
• Pack insect repellent in summer-the river plains and marshes attract mosquitoes.
