Is Seoul safe to walk around at night as a solo traveler?
One of the safest big cities in the world for it — streets stay busy late, CCTV is everywhere, and solo night walks are completely normal here. Keep standard big-city sense in nightlife districts after midnight, and watch for delivery scooters on sidewalks (the real hazard). Emergencies: 112 police, 119 ambulance — both have interpreter service.
