Iceland Mountain Roads
Iceland does not have mountain passes in the traditional sense. There are no engineered hairpins, no toll gates, no summit restaurants with terraces. What Iceland has instead are mountain roads that cross the interior highlands between glaciers and lava fields on surfaces that range from compacted gravel to river crossings where the road simply disappears into flowing water and reappears on the other side. If Alpine passes are the polished chapter of the mountain driving story, Iceland is the margin notes scrawled in pencil.
We include Iceland on SteepPass because the driving demands the same core skills – gradient management, surface reading, vehicle selection, weather awareness – amplified by remoteness that no European mountain pass can match. On the Westfjords, a gravel road climbs a ridge between two fjords with nothing on either side except ocean, wind, and the understanding that the nearest mechanic is a four-hour drive and a ferry crossing away. In the highlands, the F-roads cross terrain where you are genuinely alone – no phone signal, no other vehicles, no infrastructure of any kind.
The scale is different here. Alpine passes are measured in kilometers of hairpin. Icelandic mountain roads are measured in hours of concentration across terrain that looks like another planet because, geologically, it nearly is.
Our Icelandic Road Guides
Westfjords Passes
The Westfjords are Iceland’s most remote peninsula, connected to the mainland by a single road and populated by a number of people that would not fill a Swiss village. The roads that cross the Westfjords ridges between fjords are mountain passes by any definition – gravel surfaces climbing to 500-600 meters with steep drops on both sides and views that extend to the edge of the habitable world. Narrower, steeper, and lonelier than anything on the Ring Road.
Highland Roads Guide
The F-roads – Iceland’s designated highland tracks – are the most demanding mountain roads in this guide. Unpaved, unmarked in places, featuring river crossings that can be knee-deep or impassable depending on the hour, and crossing volcanic desert, glacial outwash plains, and geothermal areas where the ground steams. F-roads require a proper 4x4, highland driving experience, and the humility to turn back when conditions say you should.
The Westfjords Circuit
A five-to-seven day loop through Iceland’s Westfjords, linking the peninsula’s mountain ridge crossings with coastal fjord drives and some of the most remote settlements in Europe. This is slow driving – 30-40 km/h on gravel – and the reward is solitude on a scale that no other European destination can offer. The circuit includes ferry crossings, weather-dependent sections, and the understanding that your schedule is a suggestion, not a commitment.
Practical Information
Road Classification
Iceland’s road system is straightforward:
| Road Type | Surface | Vehicle Required | Example |
|---|---|---|---|
| Route 1 (Ring Road) | Paved | Any car | Main circuit around the island |
| Numbered routes | Mixed (paved/gravel) | Small car OK, 4x4 better | Westfjords, Snaefellsnes |
| F-roads (highland) | Unpaved/gravel | 4x4 mandatory | F208, F26, F35 |
F-roads are legally restricted to 4x4 vehicles. Driving a 2WD car on an F-road is prohibited, and your rental insurance will be voided if you attempt it. This is not a bureaucratic formality – the roads genuinely require 4x4 capability, and getting stuck in the highlands without it creates a genuine rescue situation.
River Crossings
Highland F-roads include unbridged river crossings. These are the defining feature of Icelandic mountain driving and the most common cause of vehicle damage.
Rules for river crossings:
- Walk the crossing first if you cannot see the bottom
- Cross in the widest, shallowest section (often upstream of the obvious crossing point)
- Engage low range / 4x4 lock before entering the water
- Maintain steady speed – do not stop in the water
- Cross early in the day when river levels are lowest (glacial rivers rise with afternoon sun)
- If in doubt, wait. Another vehicle may arrive and demonstrate the crossing, or the water level may drop
Rental insurance typically excludes water damage. Some Icelandic specialists offer highland insurance that covers river crossings – it costs more, and it is worth it.
Fuel
Icelandic fuel is expensive – approximately ISK 310-340 per liter for diesel (roughly EUR 2.00-2.20). Stations are regular around the Ring Road (every 50-100 km) but absent in the highlands and sparse in the Westfjords.
For highland driving, calculate your fuel requirement in advance. The interior has no fuel stations. Fill completely before entering, and carry a reserve if the route is long. For the Westfjords, fuel is available in the larger towns (Isafjordur, Patreksfjordur, Holmavik) but absent between them.
Season
Icelandic mountain roads have short seasons constrained by snow, daylight, and official opening dates.
| Road Type | Typical Opening | Typical Closing | Notes |
|---|---|---|---|
| Westfjords mountain roads | Jun | Sep | Gravel, weather-dependent |
| F-roads (highland) | Late Jun | Early Sep | Official opening dates published |
| Ring Road | Year-round | Year-round | Winter conditions apply |
F-road opening dates are published at road.is and enforced – driving a closed F-road results in fines and potential rescue costs. Check the website daily during shoulder season, as roads open individually over a period of weeks.
Car Rental
For Ring Road and Westfjords: a small 4x4 or crossover (Suzuki Jimny, Dacia Duster, or similar) handles the gravel mountain sections and provides confidence on wet roads.
For highland F-roads: a proper high-clearance 4x4 (Toyota Land Cruiser, Suzuki Vitara, or similar) with river crossing capability. Rent from an Icelandic specialist (Arctic Trucks, Lotus Car Rental, Blue Car Rental) rather than an international airport chain. Specialists understand highland driving, offer appropriate insurance, and will not void your coverage for F-road use.
Rental costs in Iceland are among the highest in Europe. A small 4x4 runs EUR 80-120 per day in summer. A highland-capable 4x4 runs EUR 150-250 per day. Book months in advance for July and August – availability is limited and demand is extreme.
Driving Conditions
Icelandic mountain driving is defined by three factors: wind, visibility, and surface.
Wind: Iceland is windy. Genuinely, door-rippingly windy. On exposed mountain ridges in the Westfjords, gusts can push a car sideways. On highland roads, sand storms in the volcanic desert reduce visibility and strip paint. Check wind forecasts at vedur.is before mountain driving.
Visibility: Fog, rain, and low cloud can reduce visibility to near zero on mountain sections. On gravel roads where the road edge is indistinct, this creates a situation where you cannot tell where the road ends and the terrain begins. Slow down or stop.
Surface: Gravel quality varies from compacted track to loose volcanic scree. Washboard sections shake the car and loosen components. Soft spots can grab the steering. Drive at a consistent, moderate speed (40-60 km/h on good gravel, 20-30 km/h on rough sections) and avoid sudden steering inputs.
Single-Lane Bridges
Iceland has approximately 30 single-lane bridges on Route 1 alone, and many more on secondary and mountain roads. The car closer to the bridge has right of way. Approach slowly, check for oncoming traffic, and flash your lights to communicate. Do not meet another vehicle on the bridge.
Connecting with Other Countries
Iceland is geographically isolated. The most natural pairing for a mountain driving trip is with Norway – both countries offer dramatic northern landscape with mountain roads built against challenging terrain. The driving styles are complementary: Norway is vertical and paved, Iceland is horizontal and unpaved.
Fly between Reykjavik and Bergen or Oslo. A two-week trip covering Norwegian fjord passes and Icelandic highland roads represents the full spectrum of northern European mountain driving.
