Taebaek Coal Museum in Taebaek covers the history of Korea's coal industry and the mining history of Taebaek. It displays how coal forms and how it was mined and used, along with miners' tools and recreations of old mine worksites. The mini briquette-making experience ends at 4 p.m., so start viewing early. The underground coal mine recreation lets visitors look at a mining site, but it can be frightening for children at first.
