Gwanaksan is a mountain peak in Seoul reached from Gwacheon Station, Sadang Station, and Seoul National University Station. The Gwacheon Hyanggyo route passes Yeonjuam while following the sound of a valley stream, and the summit looks out over Lotte Tower and the city of Seoul. From exit 7 of Gwacheon Station it is a 15-minute walk to the entrance, and from Gwacheon Hyanggyo to the summit takes about 1 hour 30 minutes. The slope near the summit is steep and the path to the summit marker is narrow, so hiking boots are needed.
