Getting around late at night

City subways generally stop around midnight — check the time for your line before a late night out. After that, Seoul runs 'Owl' night buses (blue buses numbered with an N, roughly 23:30–04:00) on major routes, and taxis run all night with a late-night surcharge (easiest via Kakao T). If you're heading somewhere off the night-bus network, plan to catch the last train or budget for a taxi.
