The 13 Safest Cities in the World for a First-Time Solo Traveler

12. Seoul, South Korea

Seoul blends an efficient transit network with very low violent crime and tech-forward amenities that suit first-time solo travelers. Subways are extensive and run on clear schedules, and many stations now feature English signage in tourist-heavy areas. T-money cards simplify travel across buses and subways, and mobile apps assist with route planning and translation for menus. Healthcare in Seoul is modern and internationally regarded, with English-friendly clinics in central districts. Solo travelers find organized cultural walks, K-culture tours, and food experiences that are easy to join and often small-group in size. For caution, keep an eye on crowded market areas where petty theft can occur, and have a downloaded map for offline navigation. As of November 2025, Seoul’s official tourism site lists accredited guides and neighborhood advice useful to first-time visitors. Joining a guided walking or food tour on arrival helps you learn neighborhood layouts and transit links while making social connections safely.
