Sadang Station Public Parking Lot sits directly next to Exit 1 of Sadang Station in Bangbae-dong, Seocho-gu, Seoul, and takes both large buses and passenger cars. Regional commuter shuttle buses and hiking club buses stay there from early morning before departing, and the parking area is on the large side. To receive the 50% transfer discount, you must tap your transportation card rather than insert it. Many spots on the parking lot floor are unevenly gouged.
