Iceland differs from other countries in many ways. The sparse population alone puts us in a group of very few other countries and the islands location isolates us even furter. The country is mountainous and is situated far north in the Atlantic ocean, sitting between Greenland and Norway. Iceland is the second largest island of Europe, the only bigger one being it´s neighbour Greenland. About 20% of Icelands area is populated. The central highlands and parts of northwest Iceland are uninhabited.
It is well worth your while to study Icelands road system before heading out on adventures. The road system consists of good paved roads, asphalt, gravel and mere dirt tracks so be carefull when choosing a route to go, the shortest one might not always be the best one to travel. Be especially vary when driving off asphalt surface onto gravel roads, many accidents tend to happen right at those junctions.
It is very important to get aquainted with the rules and regulations concerning off road driving. In short ANY off road driving outside of main roads/tracks is prohibited and is strictly enforced. The strict rules are due to the sensitive vegetation at this latitude and extraordinary lava formations.
Nature in this country is raw and unforgiving and there are more dangers to be taken into account than the weather (snowstorms, hurricane force winds), such as unbridged rivers, crevassed glaciers, volcanoes, geothermal areas and merciless seas.
The average temperature of the warmest month in Iceland is about 12°C (54°F) and in the coldest month about 0°C (32°F). As you move inland expect the temperature to drop by one degree Celsius for every 100m/330Feet you ascend. Warm wind- and waterproof clothes are highly recommended and lighter clothes for nice weather as well.
Icelanders in general are friendly and polite people. They are helpful, well educated, and usually fluent in one or more foreign languages. English is widely spoken as well as Danish, followed by German, Spainish as well as the Scandinavian languages so do not be afraid to ask a local for help, he or she will most likely help you or find someone who can.
