The National Prisoner of War Museum, which also serves as the park's visitor center, opens at 8:30 am and closes at 5:00 pm. It is open every day of the week rear-round, with three exceptions. The building is closed and no visitor services are provided on Thanksgiving Day, Christmas Day, and New Year's Day. However, the park grounds, including the historic prison site and the National Cemetery, are still open and accessible on these days.
