Cheong Wa Dae, Gyeongbokgung, and Gwanghwamun come into view at once, along with Bukhansan and the lower Han River. The route reaches it from Sukjeongmun by way of Baengakmaru and the 1.21 Incident Pine Tree, and there are deck stairs and rest areas along the outer fortress wall. The path has climbs and descents, and some sections are difficult to walk.
