Honouliuli National Historic Site is the location of the largest and longest-run incarceration and internment site on the Hawaiian Islands during WWII. The camp itself was 160 acres, but the park service maintains and preserves 123 of those acres. It is located on the island of O‘ahu within the state of Hawai‘i, in the Pacific West Region of the National Park Service. The camp's location was at the bottom of a gulch in the Wai‘anae mountains where prisoners would be isolated from the outside world. Honouliuli stream runs through the center of the valley. The camp was bisected by a sugar plantation-era aqueduct, separating the 4,000 prisoners of war from the 400 American civilians held there.
