Visit Amsadong and see how neolithic Koreans lived. This site was unearthed in 1925 when a flood propitiously swept the top soil away, leaving millennia-old earthenware exposed. And don’t forget to see the ostriches! A visit to Amsadong is never complete until you greet these seemingly non-germane birds.
Take Line 8 to Amsa Station and grab a cab from there. You should be able to get the rest of the way for the base fare.
