Pretty serene place to climb at Hakdam Am, posted as Juk Jang on this site. Pretty wide range of climbs, though most of them are at the harder end. Would be a cool place to get strong away from the crowds, or just spend a few quiet afternoons. Might need a car to get there, not sure how far out of the city it is. Taxi might work, but make sure to get his card when you get dropped off, better yet arrange for a pick-up.
Oh, the delicate peregrinations of those ten sensitive fingers, scuttling across the rocks in desperate Braille. - Sid Marty
