Whether you are walking Olle 9 forwards or backwards, it's quite a hike up to this viewpoint, even though this is the shortest of Jeju's Olle trails. It's worth it, though. The cache is on the left-hand side of the path if you are walking from Daepyeong-pogu to Hwasun, but you do not need to go on to the ledge to find it.
