Best F-Roads in Iceland, Ranked

F35 (Kjölur) crosses the interior between the Langjökull and Hofsjökull icecaps and is the gentlest of the flagship F-roads — our dataset rates it “easy” with “any 4x4” as the minimum, because it has no major unbridged crossings. It passes the Hveravellir hot springs and Kerlingarfjöll, which makes it the usual first taste of the Highlands. A budget crossover like a Dacia Duster or Suzuki Vitara handles it.

F208 runs through the rhyolite mountains of the northern Fjallabak to Landmannalaugar — one of the most scenic routes in the country, and the classic reason to rent a 4WD. The dataset's own field notes are blunt about the crossings: the two rivers before the campsite are lowest in the morning, so walk them first, and water above your knees means wait. The northern approach is rated for any 4x4; the southern section wants a medium 4x4.

F224 is the southern access to Landmannalaugar, rated medium with a medium 4x4 minimum. Its crossings catch people off guard after rain — you can park before the rivers and walk in, which many people do. Pair it with F208 for the full Fjallabak picture, and read how Iceland numbers its roads if the F-number system is still new to you.

F206 reaches the Laki craters, the row of vents that erupted in 1783 in one of the largest lava outpourings in recorded history. It's a rough route through lava fields, rated medium for a medium 4x4. The dataset's field note is a distance warning: the craters look close on a map but the full crater-row hike is an eight-hour-plus day, so bring far more water than you think and start early.

F88 is the northern route to the Askja caldera — a remote highland adventure with major river crossings, rated medium-hard for a medium 4x4. The Lindaá river is the one to judge: locals shrug at it, first-time visitors freak out, so check levels on road.is before you commit. If you're unsure, the eastern approach via F910 avoids Lindaá entirely.

F910 is an eastern highland route that connects toward the Askja area — remote enough that the dataset warns the full east-west run is around 150 km with nothing in between. Carry at least 20 extra litres of fuel, expect no cell signal in the middle, and tell someone your plan before you leave. Fill up at the last gas station on the way in; there are none once you're on it.

F26 (Sprengisandur) is the longest highland road in the country at around 200 km, crossing the desolate central desert between the Vatnajökull and Hofsjökull icecaps. It's rated hard, needs a large 4x4, and has very few facilities. The dataset's field notes matter here: your car drinks roughly twice the fuel on soft sand, cross rivers before 10am when the water is lowest, and stop at the Nýidalur hut to ask rangers about conditions — they know the ground better than any forecast. A Toyota Land Cruiser is the right tool.

F210 is the southern Fjallabak route — less traffic and more remote than F208, rated hard for a large 4x4. The Holmsá river is the crux: it changes by the hour with glacier melt, so cross before noon or wait until evening. The dataset puts it plainly — getting stuck out here can cost upward of 3,000 dollars in rescue, and that isn't a joke. This is a route for confident highland drivers, not a first F-road.
