Noksapyeong is the quiet side door to Itaewon — the hillside cafes and restaurants of Gyeongnidan-gil and Haebangchon (HBC) start right here, and the War Memorial and Yongsan Park are nearby. The catch is that the locker bank is small.
Coin lockers at Noksapyeong Station
Noksapyeong Station (Line 6) has T-Locker coin lockers at one spot, about 21 units, on B1 near the elevator (by the 7-Eleven). That is not many, so on a busy day check what is free first on the Noksapyeong Station page before you carry a case down.
Prices are the standard Seoul rate — about ₩2,200 (small) to ₩4,400 (large) for four hours. English screen, card, no ID.
