Keflavík International Airport is located about 50 km away from Reykjavík and there are various ways to get to and from the airport.
Getting from Keflavík Airport By Rental Car
Most, if not all, of the bigger car rental agencies in Iceland offer pick up in Keflavík for a small fee. The fee is in fact usually so small that if there’s more than two of you, it is cheaper to pay the fee than take the bus to pick up the car in Reykjavík. So if you are renting a car anyway, you should keep that option in mind. Finding the way from Keflavík airport to Reykjavík is quite straight forward but you can see the way on a map on ja.is.
Getting from Keflavík Airport By Bus
There is no public bus from Keflavík Airport to Reykjavík but you can either take the Flybus and the Airport Express. They offer similar service for a similar price but the difference is that the Flybus offers service connected with every flight while the Airport Express say on their website that transfers must be booked in advance for a guaranteed departure. On the other hand, Airport Express offers complimentary pick up and drop off service for all major hotels and guesthouses in Reykjavík while the Flybus charges 500 ISK extra per person for that service. If you are desperate for the internet after a long flight, The Flybus offers free WiFi on all their busses.
Getting from Keflavík Airport By Taxi
You don’t have to worry about being ripped off by Taxi drivers in Reykjavík like in some cities around the world. Taxis run by the meter between Reykjavík and Keflavík but sometimes they offer a fixed price which comes to about the same amount as the meter anyway. There is a taxi line outside the arrivals hall but you can also book one in advance. The average price for 1-4 people is around 15.000 ISK.
If you want to book an airport taxi transfer in advance, I recommend you contact a little company called Icelandic Taxi Tours. I’m a bit biased since it’s run by my dad but the service is reliable, he’ll go out of his way to help you with whatever you need and his car is big and comfy. He can also comfortably accommodate wheelchair users.
If you are broke or you want to want to protest against the evil axis of organized tourism there’s two things you could try to skip spending money on a ride to Reykjavík.
First of all, you could try to hitchhike. Hitchhiking is pretty common and safe in Iceland but I don’t know how easy it is to get a ride on this particular route so you might have to walk a long way with all your luggage. Alternatively, you might want to try befriend whoever sits next to you on the plane and if he or she is a local, there’s a good chance their car will be at the airport or that they have a ride waiting for them when you land. People are nice, they might offer you a ride.
