F-roads (from Icelandic «fjallvegir» — «mountain roads») are the network of gravel routes in the center of the island, with no asphalt and no services. Usually open from mid-June to mid-September; the rest of the year they're closed by snow and officially shut. They lead to the most beautiful parts of the country: Landmannalaugar, Þórsmörk, the central deserts.
Main rule: a regular car will not get through the F-roads. That's not rental marketing — it's Icelandic law plus physics. Here's what you need to know.
What vehicle you need
Per Icelandic Traffic Law, F-roads allow 4WD vehicles only. Going in 2WD = legal violation (fine €600–1500) + insurance won't cover damage.
- Easy F-roads (F35 Kjölur, most of F26 Sprengisandur) — Suzuki Vitara, Dacia Duster 4×4, Toyota RAV4. High clearance, 4×4.
- Hard F-roads (F88 to Askja, F26 with the deep fords, F210 Fjallabak) — big jeep needed: Land Cruiser, Toyota Hilux, Ford F-150 with winch.
- F26 / F35 / most F-roads without river crossings — a standard 4WD is enough.
The main danger: rivers and fords
Many F-roads have no bridges. Rivers must be forded. This is the top reason for damaged tourist vehicles.
If a river looks calm, it doesn't mean it's safe. On mountain rivers:
- Depth changes during the day — less in the morning, more in the evening (snow/glacier melt)
- Bed is uneven, may have rocks
- Current is stronger than it looks
- Depth at headlights = risk of flooding the engine = repair €5000–15,000
What rental insurance does NOT cover
Even with Premium insurance, there are exclusions:
- Engine flooding in a river — ALWAYS not covered. No insurance covers water in the engine.
- Damage from driving off a non-F-road in 2WD — breach of contract.
- Damage to underside, exhaust, oil pan from rocks on gravel — often not covered by standard insurance.
- Ash/Sand damage from volcanic dust and sand — separate S&A insurance.
- Storm wind damage (doors ripped off) — separate Wind Protection.
Which F-roads are open right now
Real-time road status on Vegagerðin (Iceland Road Administration): umferdin.is. Map updates live.
Typical opening dates (may vary):
- F35 Kjölur — late June
- F26 Sprengisandur — early July
- F88 Askja — July
- F210 Fjallabak — late June to early July
Usually close mid-to-late September with the first snow.
Top F-road destinations
1. Landmannalaugar (via F208 or F225)
One of Iceland's most beautiful spots — multicolored rhyolite mountains, geothermal springs, the famous Laugavegur trek (55 km to Þórsmörk). Reachable by car, but requires 2 river fords (Krossá and smaller ones).
2. Askja and Víti (via F88)
Massive volcanic crater with a lake. F88 is hard — several serious fords across Lindaá river. Only on big 4WDs or with a guide.
3. Þórsmörk (via F249)
Green valley between glaciers. Only «super jeeps» can reach it — the road crosses Krossá, a powerful glacial river. Most people park at Hvolsvöllur and take an off-road bus.
4. Kerlingarfjöll (via F347 off F35)
Geothermal zone in the center, colorful mountains similar to Landmannalaugar but without crowds. Easy F-road, doable with a standard 4WD.
5. Sprengisandur (F26)
The longest cross-country traverse — 250 km of desert between Hofsjökull and Vatnajökull glaciers. Ford across Tungnaá can be serious.
5 tourist mistakes we see
- Driving 2WD onto the first F-road «it's dry anyway». One rock underneath = €3,000 repair + contract breach.
- Not checking fords before crossing. Depth is easy to underestimate. Especially evenings, when ice melts faster.
- Going alone. F-roads have no cell coverage. Stuck = wait hours/days for someone to pass. Minimum 2 vehicles.
- Not filing a plan. Submit on Safetravel.is. If you don't return on time — search and rescue starts.
- Driving without a full tank. No fuel stations on F-roads. Full tank + jerry can mandatory.
Mandatory gear in the vehicle
- Full tank + 20-litre jerry can
- Spare tire in perfect condition (F-roads cut tires often)
- Jack + lug wrench
- Chains or sand mats
- 5+ litres of drinking water and a day's food
- Warm clothing (even in summer)
- GPS not only on phone (paper map or offline maps)
- Power bank
- First aid kit
NOMAP jeep tour — alternative to going solo
If you want to see the highlands without breaking the car/nerves/planning — our «Iceland 360°» tour. Big 4WD jeep, experienced driver, route with vetted fords, radios, satellite communication in case of emergency.
What we do that solo travelers can't:
- Check weather and road status in real time
- Know alternatives if main route is closed
- Our vehicles have Wind/Ash/Sand insurance + raised limits
- Drive minimum 2 vehicles in convoy
- We've seen every ford 20+ times — know where it's safe
