This itinerary is made for you who want to explore the Highlands of Iceland.
The Icelandic highlands are only open in summer. Exact opening dates depends on current conditions so it's always good to check before you go on www.road.is. Usually they open early June and close end of September when the first snow comes.
To drive in the highlands you must have a 4x4 vehicle. Some roads are passable with a smaller 4x4 (ex. a Dacia Duster), and some roads require a big 4x4 with Snorkel to cross deep rivers (ex. Toyota Land Cruiser or Land Rover Defender). The bigger car, the more places you can go.
The most important thing to know is that river crossings are never covered by the insurance. If you get water in the engine you will be liable to pay the full value of the car. In the summer most river crossings are possible to do with a smaller 4x4. But this of course depends on current conditions. If it has been raining a lot the rivers can be very deep and dangerous to cross.
This itinerary is designed to be possible to drive with a small 4x4 if conditions are good. Remember to always drive slow through rivers and never against the current. Always judge the conditions on the day and if you are unsure, wade out to see how deep it is.
