Getting there

Catch the train (line 2) to Jangsan Station, take exit 12 and look around for a mountain. When you see a mountain, walk towards it and you will arrive at the starting point. It should take approx. 20m to walk to the trailhead.

Route/Trail notes

Unless you can read Korean, the track can be quite difficult to follow. There are a lot of signs pointing in different directions and is easy to get lost. If you cannot read Korean, I reccommend following someone else up the mountain so you won't get lost. Straying off the path can be dangerous as there are active land mines on the mountain. Other than being easy to get lost, the hike is generally quite easy and is suitable for all ages.
