In reply to Removed Userherblai:
I have climbed in Seoraksan a couple of times ... you get yourself to Sokcho, get a bus to Seorak-dong & stay in one of the slightly grotty hotels, or as close to the park gate as you can manage & stay somewhere pricier & a little weird, like the Kensington Stars hotel. Walk in about an hour following signs for Towang-san or Paekundae (where you could also stay at the hut, if there's room). There are quite a few falls - certainly good for a short weeks stay, but very hit & miss as to conditions - I was there for a week in February & it was warm, wet & I barely made it out of bed. I have had previous trips with no snow & great ice, & others with people getting buried in huge avalanches
There are other spots that also look good - Shilso Pokpo is also in the park, near Osaek-ri, & looks good, & there's a guest house on the road.
But in the light of recent experience I question if I would actually fly there for ice ... different story if you are living or working there & can take advantage of a weather window.
Try the Korea on the Rock website ... Not always current but a few active users.
