Going to Iceland? Great choice! I have some advice about driving around the island, and what challenges await you. Especially if you are taking my 14 days road trip around Iceland, the hints here will be very useful!
The country has no trains. Buses are almost non-existent. Hitchhiking (although possible) can be frustrating, as there are not that many empty cars passing by. There is no better way to explore this over 100 000 square km (40 000 square miles) island than by car!
