Tap water: ✅ Safe to drink from the tap; locals often prefer bottled for taste, not safety.

Safety: South Korea is extremely safe with very low crime — Seoul and Busan feel secure around the clock. The main things to watch: heavy nightlife districts on weekends and spring dust days. Superb, cheap public transport everywhere.

For most short tourist trips, citizens of the US, UK, EU/Schengen, Canada, Australia and New Zealand either enter visa-free or get a simple online authorisation (an eVisa or eTA) before flying. Typical visa-free stays run 30–90 days. Some countries want a visa arranged in advance, and a growing number ask you to fill an online arrival or eVisa form even when 'visa-free' — so always check the official portal for your exact nationality before you book.
