* International flights arrive into Keflavik airport - this is about 32 miles south west of Reykjavik and takes about 45 minutes to travel to the city centre from the airport. You can take a taxi into town, but it is expensive - around £70. We found a great option was to take the Flybus coach. It connects to all the flights at the airport. You buy your ticket from the desk at the main exit, it is also cheaper if you buy your return ticket at the same time. It costs £10 per person each way and is free for children under 11 years. They have a website which lists all their stops. It leaves from right in front of the terminal building and shuttles you into the Bus Terminal in Reykjavik. From here, you transfer to a small bus and they drop off at the various hotels. If your accommodation doesn't appear on the list of stops, there will probably be a stop within walking distance. We stayed in an apartment, but got the bus back to the airport from a hotel close by. Departures from the city are timed to connect with international flights.
* The flight time from the UK to Iceland is supposed to be around 3 hours. Our flight to Reykjavik actually took 2 hours and 20 minutes, while the return leg took just 2 hours. It is thus very accessible and an easy journey from the UK, especially if you have young children.
* If you only want to see Reykjavik, then you do not need a car. It is a small place and is really easy to travel around on foot. The bus network is also very good, if you want to go a little further in the city.
* We based ourselves in Reykjavik but hired a car for 3 days to see the main sights outside the city. Iceland is a small country - only 500km across so you don't cover vast distances even if you do want to explore further. The Ring Road is great to drive on - not too much traffic. Some of the other roads are more like gravel tracks, so you need to be aware of that.
* It can be difficult to travel overland in Iceland in the interior, especially in the winter time. If you need to go any distance, you would need to take an internal flight. There are no railways here - the terrain makes them impossible.
* Renting a car can be expensive, I would definitely recommend arranging this in advance over the internet. We did this and ended up only paying around £30 per day for a small car. We used Procar, their offices in Reykjavik are very easy to find and picking up and returning the car was no problem. You should also take out the gravel insurance - apparently lots of people have chassis damage and get charged big amounts for this, so better safe than sorry. Petrol prices are also very high. Parking in Reykjavik is free on Sundays and in the evenings.
* We found renting a car gave us a lot of freedom. There are plenty of organised coach tours to all the main sights, but you get to see a lot more in your own hire car. Parking in the city was really easy for us too. Driving was a pleasure. There were next to no cars on the road once you got out of the city. The landscape is stunning and you will want to make lots of stops for photos and just to look at the amazing views. Highway 1 is mostly paved. The speed limit is 90 km/hour and you must have headlamps on at all times. We only had a small compact car so did not drive on any of the "difficult" roads, but even the main routes can become gravelly and bumpy in parts. We had no problems with our car though and would recommend driving around to see a bit more of this stunning country.
