Five websites every traveller should know about:
Public Transport in Iceland (www.publictransport.is) Good overview of routes.
Safetravel (www.safetravel.is) Learn about minimising risks; log hikes.
Icelandic Met Office (Veðurstofa Íslands; www.vedur.is) Never underestimate the weather in Iceland. Get a reliable forecast from this website (or call 902 0600, and press 1 after the introduction).
Vegagerðin (www.road.is) Iceland’s road administration site details road openings and closings around the country. Vital if you plan to explore Iceland’s little-visited corners and remote interior.
Carpooling in Iceland (www.samferda.is) Handy website that helps drivers and passengers link up. Passengers often foot some of the petrol bill. It's a savvy alternative to hitching (for passengers), or a way to help pay for car hire and fuel (for drivers).
