Check the map and one thing very important, when do you want to go there - do not do it in rainy season.

Take line 3 (orange line) subway. alight at Anguk station and go out from exit 2.

Hi there, you may wish to take a copy of the map at the Tourist Information Centre near the start of the walk to Bukchon Hanok Village. This is located about 1 block ahead from exit 2 of Anguk Station (subway line 3). The map that they have there states very clearly on how to get to Samcheong dong.
