Donglim Reservoir, Gochang (고창 동림저수지)

Every year, more than 200,000 spectacled teals (the color takes its name from the bird) fly about in an orderly manner above this beautiful reservoir, which was voted "Kingdom of migratory birds" in 2004 in a national survey.
Built in 1935, the 3.82-square-kilometer reservoir is also famous as a fishing hole.
