Keflavík International Airport: The airport is about 5 km from Keflavík town, not in its walkable centre. For the budget transfer, use the public bus from outside the terminal (ask the information desk for the stop): roughly 10–15 minutes and about 2,400 kr in the latest local guidance. A taxi is faster but not a bargain—roughly 2,200–2,700 kr to central Keflavík. Do not buy a Reykjavík Flybus ticket if your bed is in Keflavík; that service is for the capital, 45–75 minutes away.
