First-day checklist
- Confirm your arrival airport: Copenhagen Airport (CPH), Billund Airport (BLL), Aalborg Airport (AAL) and Aarhus Airport (AAR).
- Choose a first transfer: metro, train, official taxi, hotel transfer, regional rail or bus.
- Carry a payment backup in Danish krone (DKK).
- Set up roaming, eSIM, local SIM or offline maps before leaving arrivals.
- Denmark is generally safe, but watch belongings in busy tourist areas, stations, nightlife zones and crowded events.
- Punctuality, privacy, personal space, quiet public behavior and direct communication often matter.
- Save accommodation details and first local contact offline.
