To get to Hwangjeok Pokpo (falls) from Seoul:
First head to Daejeon
Take the Yuseong exit
Follow the signs to Gyeryong Mountain National Park
Once you arrive at the park, drive to the campground(camp sites).
if you park at the top of the hill, walk about 100 meters back down the road from which you drove up
When you start walking the small, narrow road that takes you to the campsites and the road turns steep, look for a trail on your left. The trail is about halfway between the campsites and the main road. It is also very faint, so look carefully. there might be snow and therefore footprints.
Follow the trail veering right so that it takes you through a small gulley. Eventually, the trail starts heading up the valley. Follow the trail for about 20 - 30 minutes and you'll walk right into the face.
Total hike-in time is about 30 minutes.
its a small area but gets shade all day. today is 50 degrees farenheit so keep that in mind. im sure its starting to melt away. you may have better luck at maebawi, but you'll have t batttle the crowds
hope this helps
call/write if you have any more questions
Fall: To retreat in dynamic fashion from a climb.
