Canadian Grizzly, i live in haeundae, im in vietnam right now. when i get back in a couple weeks, i have a cd of korean mountain mapps compiled by a korean friend of mine. can make a copy.
also, try searching in naver of daum.
name of mountain in korean + "jido" (in korean, no korean on this keyboard, sorry). do an "I-mi-ji" search
that often works for me.
for national park maps, google "korea in the clouds"
