Seomjin River Train Village (섬진강 기차마을)

Kudos to the Gokseong district office which has managed to create a lovely tourist attraction out of abandoned railroads. A brief steam train ride (they don't make 'em like this anymore, literally) is available for tourists, who can also enjoy a bike hike on a trail bike or a romantic walk beside the train track.
