Minidoka National Historic Site

Minidoka National Historic Site

Set in Idaho and Washington, Minidoka National Historic Site is one of the NPS historical units that rewards visitors who treat it as both a destination and a classroom. During World War II, over 120,000 people of Japanese ancestry were forcibly removed from their homes and incarcerated without due process of law. Although little remains of the barbed-wire fences and tar-papered barracks, the Minidoka concentration camp once held over 13,000 Japanese Americans in the Idaho desert.

Minidoka preserves their legacy and teaches the importance of civil liberties.

At Minidoka National Historic Site, the historical park designation affects everything from trail layout to the kinds of programs offered. Plan for an afternoon of quiet, thoughtful exploration.

Getting There

Reaching Minidoka National Historic Site is straightforward once you know the route. Minidoka National Historic Site is located between the towns of Twin Falls and Jerome, Idaho in south central Idaho.

By Car

Most visitors arrive by private vehicle or rental car. Road conditions vary with weather and construction, so check the park's alerts page the day before you travel. Pay attention to GPS directions in rural stretches—some apps route drivers onto unmaintained service roads rather than the signed park entrance.

Nearest Airports

Regional airports provide the most convenient access for long-distance travelers. For the most current airline service and driving distances, cross-reference flight options with the park's contact page. Budget extra drive time from any airport, especially if you arrive after dark or during winter weather.

Public Transit and Tours

Direct public transit is limited at most National Park Service sites, but guided day tours and shuttles sometimes operate from nearby cities during peak season. Rideshare options are often reliable in gateway towns but may drop off outside the park boundary rather than at specific trailheads or visitor centers.
