Common mistakes first-timers make
Hard-won tips from trip reports — packing, payments, and pacing.
Reviewed:
Planning
- Overpacking neighborhoods into one day (transfer + walking time adds up).
- Ignoring Korean holidays and reservation reality for popular restaurants.
- Treating another nationality’s K-ETA / visa rules as your own.
Money & apps
- Relying only on Google Maps for last-mile walking.
- Not carrying a backup payment method or modest cash.
- Skipping Naver Map offline / translation packs until you’re already lost.
Entry & connectivity
- Leaving K-ETA or e-Arrival to the jet bridge.
- Buying the wrong SIM size / losing the eSIM QR with no offline copy.
- Assuming temporary K-ETA exemption means “no forms at all” (e-Arrival may still apply).
On the ground
- Standing in the hopping-off side of subway doors.
- Underestimating palace/outdoor heat or cold — check weather the morning of.
Mindset
Korea rewards wiki facts + community context. If something is time-sensitive (concerts, pop-ups, limited drops), ask the community with dates and neighborhood.
Sources for durable rules should be official; trip reports are great for texture, not for immigration law.
