The Cheong-Gwang Traverse is a premier long-distance hiking and trail running route, approximately 25km in length, that crosses southern Seoul and Gyeonggi-do. This route completely traverses a massive mountain ridge right within the metropolitan area, stretching from Cheonggyesan in Seoul to Gwanggyosan in Suwon. It can be completed South-bound (starting at Cheonggyesan and heading to Gwanggyosan) or North-bound (starting at Gwanggyosan and finishing at Cheonggyesan).
