Sticking to Iceland’s paved Ring Road (Route 1) will take you to famous waterfalls and coastal cliffs. But true backcountry wilderness begins when you turn onto mountain tracks marked with the letter „F“. How to drive Island F-Roads?
The Icelandic Highlands and the colorful geothermal oasis of Landmannalaugar represent some of the most striking, untamed landscapes on Earth.
Here is our practical guide to navigating Icelandic F-roads, river fording safety, and what to expect on the legendary route into the volcanic interior.
Island F-Roads (content)
What Are F-Roads and What Are the Rules?
The prefix „F“ stands for Fjallavegur (mountain road). These unpaved tracks traverse the uninhabited interior and feature:
- Rough gravel, sharp volcanic rocks, deep ruts, and washboard corrugated surfaces.
- Steep mountain gradients with no guardrails.
- Unbridged glacial and spring-fed river crossings.
Legal Requirements: 4×4 Only
Driving a two-wheel-drive (2WD) car onto any designated F-road is illegal under Icelandic law.
- Violators face heavy police fines.
- All rental insurance is voided instantly.
- Recovery towing fees from the Highlands cost thousands of Euros.
Navigating Route F208 to Landmannalaugar
Landmannalaugar is accessible via several routes:
- F208 North (from Route 26 / Landmannaleið F225): Mostly paved or smooth gravel with no major river crossings until the final ford directly in front of the main campsite.
- F208 South (from Route 1 near Vík): A demanding 4×4 wilderness track featuring over 20 river fords, steep climbs, and breathtaking volcanic desert scenery.
Driving our seasoned 4×4 across the 26 km washboard section of F208 shook every screw in the vehicle, but the dramatic scenery shift into black volcanic deserts, neon-green moss, and multicolored rhyolite mountains made the journey unforgettable.

The Art of River Fording: How Not to Drown Your Car
Crossing an unbridged glacial river is the most adrenaline-pumping part of Highland driving. A few critical rules prevent catastrophic vehicle damage:
1. Stop and Scout on Foot
- River levels fluctuate throughout the day. Glacial melt peaks in the late afternoon and after rainstorms.
- Never enter a river blindly just because another vehicle crossed earlier.
- Wade in to test depth, current speed, and hidden submerged boulders if you are uncertain.
2. Know Your Vehicle’s Air Intake Height
- Water entering the engine air intake causes catastrophic hydraulic lock (engine destruction).
- Standard rental insurance policies never cover water damage.
3. Fording Technique
- Engage 4WD low-range (4L) and turn off traction control systems.
- Enter the water in a wider, shallower section rather than narrow deep bottlenecks.
- Drive slightly diagonal with the current, never straight against it.
- Maintain a steady, slow walking pace (approx. 5–10 km/h / 3–6 mph). Create a small, steady bow wave in front of the bumper to keep water away from the engine bay.
- Never change gears or stop in the middle of a river.
Our Þórsmörk Reality Check:
While attempting to reach Þórsmörk valley, we successfully cleared five river fords. At the sixth crossing (the Krossá river branch), water depth measured over 40 cm with strong glacial currents — higher than our air intake. We chose safety over bravado and turned around. Turning back when conditions exceed your vehicle’s capability is an essential part of Icelandic travel.
The Reward: Soaking in Landmannalaugar’s Natural Hot River
Located at the edge of the ancient Laugahraun lava field, Landmannalaugar is famous for its rainbow-colored rhyolite peaks (Brennisteinsalda, Bláhnjúkur).
The ultimate reward after a grueling drive is the natural geothermal stream right next to the campsite:
- Boiling groundwater emerges from beneath the lava bed and blends with cold mountain runoff.
- Temperature averages a relaxing 38–40 °C (100–104 °F).
- There are no built facilities or lockers — you change on an open wooden boardwalk in the cold air, making the plunge into the steaming water all the more invigorating.
Frequently Asked Questions (FAQ)
Due to snow, ice, and spring mud melt, F-roads remain closed for 8 to 9 months of the year. They generally open between mid-June and early July and close after the first severe autumn snowfall (typically mid-to-late September). Check road.is daily for real-time status.
Yes. If you take the northern approach via Route 26 and F208 North, you can drive all the way to a large parking area just before the campsite. There is one deep river ford right in front of the camp, but you can leave your vehicle in the safe parking lot and walk across the pedestrian footbridge (5–10 minutes on foot).
For standard F-roads like northern F208, a compact 4×4 SUV (such as a Dacia Duster, Suzuki Jimny, or Toyota RAV4) is sufficient. For deeper crossings and rugged southern Highland tracks (F208 South, F26 Sprengisandur, Askja), a larger high-clearance 4×4 with a raised snorkel (such as a Toyota Land Cruiser or Hilux) is strongly advised.
