In Geoje-si, this modest but worthwhile museum provides hard-to-find information about the POW camp experience during the Korean War. Just by the gate is a tourist info centre that has maps but no English-speaking staff. The new Geoje Tour Monorail is accessed here.
From the Gohyeon intercity bus terminal, it's a 30-minute walk; a â‚©5000 taxi ride will get you here in a few minutes.
