Highland routes
The highland routes are in Icelandic maps preceded by "F" provided for example F26. With "F" is the Icelandic word is meant Fjallaleið, which translated means as much as mountain states. For operating on these routes, but you should already have a four-wheel drive vehicle. Ideally, with a high wheelbase. With a car fails usually already at the fords, but the bumpy moguls to give their share to an accelerated aging of the vehicle.
Nevertheless, there are also some tracks that can be used without a risk with a normal car. However, note that in these lines always leaves a unpredictable weather with you. In a coup weather, you can very quickly get into very awkward situations. Sand and snow storms can occur suddenly.
In case you want to drive your car to Dynkur waterfall, this is only possible with all-terrain vehicles. With a car they fail here. Not a ford with a high water level are the problem, but the larger rocks strewn track, a high wheelbase makes the car needed.
Highland routes, which can be largely driven by a normal car, would be:
F 35 Kölur route, no special problems
F 550 Kaldidalur, no particular problems
F 864 Dettifoss, no particular problems, however unpleasant 42 kilometers long moguls (corrugated iron)
F 338 power poles line, no particular problems
F 225 Landmannalaugar; from the north to cope is free of ford
