The short answer, before the detail

If you are wondering what are f roads in iceland, they are the country's interior highland and mountain tracks, designated by the letter "F" before their route number (such as F208, F225, or F249). In Icelandic, the prefix stands for fjallvegur (mountain road). Under Icelandic law, F-roads are open exclusively to four-wheel-drive (4WD) vehicles and remain closed for eight to nine months of the year, generally opening between mid-June and early July and closing in September.

For photographers, an F-road designation is a legal boundary and an access window. If a volcanic crater, glacial viewpoint, or braided river canyon sits along an F-road, you cannot reach it in a standard two-wheel-drive (2WD) rental car without voiding your insurance contract. The files carry season and access notes, not live conditions. Check vedur.is and road.is for current weather and road status before you leave paved asphalt.

What are F-roads in Iceland, exactly?

Iceland's road network splits into distinct legal classifications: primary highways such as Route 1, secondary rural routes, ordinary gravel tracks, and mountain roads (F-roads). When you ask what are f roads in iceland, you look at the most demanding tier of the public network. The F prefix indicates a mountain track that receives minimal maintenance. In most cases, the F-road takes the number of the lowland road from which it extends. For instance, Road 208 runs inland from the south coast as a standard secondary gravel road until it passes the boundary into the Fjallabak Nature Reserve, where it becomes F208.

F-roads differ fundamentally from standard rural gravel roads. Iceland contains thousands of kilometres of non-F gravel routes, such as the approach to Aldeyjarfoss along Road 842 or the paved-and-gravel routes surrounding Barnafossar. A standard gravel road is maintained for ordinary traffic, has bridges over every significant waterway, and is legally accessible in a 2WD passenger vehicle. F-roads feature steep gradients up to 15 percent, deep ruts, exposed basalt bedrock, loose volcanic tephra, and unbridged river crossings.

The legal restriction to 4WD vehicles is absolute. Driving a 2WD vehicle on any road with an F designation violates Icelandic traffic regulations. Beyond statutory fines, every rental agency in Iceland forbids 2WD vehicles on F-roads. Entering an F-road in a prohibited vehicle breaches the rental contract, immediately invalidates all insurance coverage (including collision damage waivers and third-party liability riders), and leaves the driver personally liable for mechanical recovery charges that routinely exceed 400,000 ISK.

Some interior roads lack an F prefix but still run through rugged highland terrain. Route 35 (Kjölur) and Route 550 (Kaldidalur) were stripped of their F designations after grading improvements, but most rental car agencies still prohibit 2WD cars on them due to tire damage and undercarriage strikes. The F marker guarantees that 4WD is mandatory, but the absence of an F does not guarantee that a track is passable in a compact hatchback.

When do Iceland's highland F-roads open and close?

Highland tracks do not operate on a fixed calendar. The opening of each F-road is decided individually by the Icelandic Road and Coastal Administration (Vegagerðin) based on snowmelt, subsoil thawing, and moisture levels. In early spring, thawing ground turns highland volcanic ash into deep mud. Driving on these routes during the thaw destroys the sub-base and causes rutting, leading authorities to classify them as ófært (impassable) or impose strict environmental closures (akstur bannaður).

Current open and closed status varies significantly per road. Lower interior tracks, such as the northern approach of F208 or the Kaldidalur corridor, often open between June 5 and June 15. Higher routes, including F88 into Askja or F249 into Þórsmörk, regularly remain closed until late June or the first week of July after heavy winter snowfall. Historical logs published by Vegagerðin show that deep interior passes may not clear until July 10 in colder years.

Closures begin in autumn with sub-zero freezes and snowstorms. Most F-roads shut down between mid-September and early October. Once closed for winter, maintenance ceases entirely until the following summer. The table below outlines the typical operating windows for major highland routes across the country.

Road Number Region / Primary Destination Typical Opening Range Typical Closing Range
F208 (North) Landmannalaugar via Sigalda June 10 – June 20 Late September – October
F208 (South) Fjallabak Sydra / Skaftártunga June 20 – July 5 Mid-to-late September
F225 Landmannaleið / Hekla base June 15 – June 25 Late September
F249 Þórsmörk / Krossá river valley June 15 – July 1 October (weather dependent)
F88 Askja caldera via Herðubreið June 20 – July 5 Mid-September
F347 Kerlingarfjöll geothermal valley June 15 – June 25 Late September – October

This access schedule shapes the photographer's planning calendar. The highland light window coincides with late June, July, and early August. During this period, Iceland experiences usable daylight around the clock, with extended golden hours stretching across midnight. If you plan a trip in late September to capture autumn tundra colours or early aurora activity over the highlands, you face the real risk of early snowstorms closing your target tracks overnight.

F-road driving requirements: vehicle, insurance and river crossings

Meeting proper f-road driving requirements requires attention to vehicle mechanics, contractual terms, and water levels. A vehicle badge that reads "AWD" or "4x4" does not automatically mean a car is cleared for every mountain road. Many modern crossover SUVs have all-wheel-drive systems engineered for snowy city streets. These vehicles lack the minimum 20 centimetres of ground clearance needed to clear protruding basalt rocks, and their low-slung air intakes sit close to water level.

Rental contracts explicitly classify which vehicle classes are approved for mountain roads. A compact crossover may be permitted on gravel secondary roads, but barred from numbered F-roads. Larger 4WD platforms carry the necessary chassis height, heavy-duty suspension, and low-range transfer cases. Confirm that your specific vehicle category is permitted on F-roads in the signed rental terms before driving off the rental lot.

Insurance coverage on mountain tracks demands clear scrutiny. Standard rental packages, including Collision Damage Waiver (CDW) and Super Collision Damage Waiver (SCDW), carry specific exclusions under Icelandic rental law:

  • Undercarriage damage caused by scraping rocks, boulders, or road ridges.
  • Water damage to the engine, transmission, electrical systems, or interior caused by river crossings.
  • Tire punctures and wheel rim damage from sharp volcanic rock.
  • Damage caused by wind-blown volcanic sand and ash unless a separate Sand and Ash Protection rider is purchased.

Unbridged river crossings represent the most hazardous component of highland travel. Mountain rivers in Iceland are fed by glacial meltwater and rain. Their volume fluctuates dramatically throughout a single day. A river crossing that measures 25 centimetres deep at 08:00 can surge past 60 centimetres by 17:00 as summer sun accelerates glacial melting upstream, or within hours of heavy rain. Glacial water is opaque and milky grey; you cannot see submerged boulders, sandbanks, or drop-offs from the riverbank.

Driving through moving water requires strict technique. Engage four-wheel drive and low range before entering the stream. Walk the crossing first if depth is uncertain, provided the water is safe to enter on foot. Enter the river downstream of the deepest current, moving diagonally with the flow. Maintain a steady walking pace of roughly 5 to 7 km/h to create a gentle bow wave in front of the bumper. Avoid stopping in mid-stream, avoid shifting gears while immersed, and stay out of rivers whose surface shows breaking white rapids or water reaching above the wheel hubs.

Driving speeds on F-roads are slow. Corrugated washboard gravel surfaces, embedded stone ridges, and deep potholes shake camera gear violently inside the cabin. Secure your camera bodies and lenses in padded cases. Calculate your travel time assuming an average moving speed of 25 to 40 km/h on dry tracks, dropping to 15 km/h across rocky or wet sections. High speeds on washboard surfaces lead to loss of traction and sidewall punctures.

Cellular phone service drops off sharply once you leave the lowland coastal ring. In deep highland valleys such as Landmannalaugar, Þórsmörk, or Askja, base stations are blocked by mountain ridges. Navigating via cloud-dependent smartphone apps without local caching will leave you stranded without a map. Waypoints and basemaps must reside entirely on your device hardware before you drive away from the Ring Road.

Which highland photo locations actually need an F-road?

Photographers planning an itinerary must separate locations requiring true iceland highland road access from those accessible on regular secondary roads. Many dramatic interior landscapes sit deep within the central volcanic belt and require navigating F-roads, while others only require patience on well-maintained gravel.

The rhyolite mountains and obsidian lava fields of Landmannalaugar (63.9912° N, 19.0601° W) require F-road travel depending on the chosen route. Approaching from the north via Road 208 from the Sigalda power station is mostly paved or smooth gravel until the final short stretch, but entering via F225 (Landmannaleið) or southern F208 requires crossing multiple unbridged rivers. At the entrance to the main campsite, the final river crossing before the parking lot turns away dozens of standard SUVs every week. The safe alternative is parking in the designated lot just before the river and crossing the pedestrian footbridge with your camera pack on foot.

The glacial valley of Þórsmörk (63.6807° N, 19.4826° W) sits at the terminus of F249. This is one of the most demanding tracks in southern Iceland. While the first section of F249 past Seljalandsfoss is simple gravel, the road quickly degenerates into glacial outwash plains cut by dozens of volatile streams, culminating in the Krossá river. The Krossá shifts channels hourly and regularly traps standard rental 4WDs. Photographers shooting the southern ridges of Þórsmörk should leave their rental vehicles at the road entrance and utilize highland bus transfers or modified super-jeep operators.

The caldera of Askja and the volcanic lake Víti (65.0315° N, 16.7490° W) require traversing F88 or F910 across vast lava deserts north of Vatnajökull. F88 features deep, fast-flowing river crossings at the Lindaá and Grafarlandaá rivers. Farther west, the geothermal peaks of Kerlingarfjöll (64.6321° N, 19.2882° W) lie along F347, accessed from Road 35. While Road 35 itself no longer carries the F prefix, it remains a rough, unpaved route prone to heavy washboard ruts that slow travel to 40 km/h.

Contrast these highland routes with classic waterfalls often mistaken for F-road destinations. Aldeyjarfoss, known for its symmetrical basalt columns framing a turquoise torrent, sits at the northern end of the interior Bárðardalur valley. The approach along Road 842 is an ordinary gravel road. The final 4 kilometres switch to the start of the Sprengisandur highland route (F26), which requires a 4WD vehicle. However, it does not involve deep river crossings to reach the designated waterfall parking lot.

Waypoint files provide clear utility here by distinguishing legal classifications and approach constraints. When you examine a waypoint in the Landscape map or Waterfall map, verify the access metadata. The file notes identify whether the approach is paved, graded secondary gravel, or true F-class terrain requiring high clearance. Understanding these distinctions prevents route failures where a planned sunset location cannot be reached because your vehicle is legally barred from the approach track.

Group your highland shooting days together. Driving 40 kilometres up an F-road consumes three to four times more fuel and time than covering the same distance on Route 1. Establishing a multi-night base at the edge of the highland plateau (such as near Hella in the south or Mývatn in the north) allows you to monitor highland weather patterns and enter the interior during favourable light windows without wasting hours repositioning across the country.

How to plan an F-road day around light, not around distance

In lowland photography, travel time correlates closely with distance. On Route 1, covering 60 kilometres takes roughly 45 minutes. In the highlands, covering 60 kilometres along an F-road routinely requires two to two-and-a-half hours of continuous driving, excluding stops for river assessments or gate openings. Photographers must build their daily shooting schedules around the speed of the road.

Consider a practical timing model for shooting sunset and midnight sun at Landmannalaugar from a southern accommodation base near Hvolsvöllur:

  1. Leave the lowland base at 17:00 to cover 40 km of paved road to the F-road junction, arriving at 17:35.
  2. Drive the 45 km stretch of F225 or F208 at an average speed of 30 km/h, reaching the trail parking area around 19:15.
  3. Allow 45 minutes to hike with tripod, camera body, and lenses from the parking area to the summit ridge of Bláhnjúkur.
  4. Set up at 20:00 to monitor changing shadows as the sun skims the northern horizon between 22:30 and 00:30.
  5. Pack gear at 01:00, descend to the vehicle by 01:45, and drive the return F-road section in early morning dawn light, arriving back at the lowland base around 04:30.

The midnight sun of June and July makes this schedule practical. Between June 10 and July 20, Iceland experiences no astronomical or nautical darkness. The sun dips slightly below the northern horizon before rising again, providing a three-hour golden and blue hour transition. Returning across rugged F-roads at 02:00 occurs under bright twilight, eliminating the hazard of navigating boulder-strewn tracks or assessing river levels in darkness.

By early September, this dynamic shifts. Astronomical twilight returns, delivering dark skies from 22:00 to 04:00. This opens up opportunities for photographing the aurora borealis over highland volcanic peaks, but introduces operational friction. Crossing unfamiliar glacial rivers or dodging deep washboard ruts at 03:00 in freezing conditions demands caution. If you plan September highland shoots, identify river crossings during daylight hours, record exact GPS tracks on the inbound journey, and avoid crossing rising water after dark without clear visual confirmation of the riverbed.

Remember your software boundaries during route planning. The files are waypoints. Your own mapping app (Gaia GPS, OsmAnd, Organic Maps, a Garmin) does the routing. Loading exact coordinates into your offline mapping tool allows you to see the spatial relationship between parking points, shooting perspectives, and road approaches before you leave cell service behind.

Getting F-road waypoints onto your phone before you lose signal

The interior of Iceland contains virtually no commercial cellular data coverage. Once you leave the Ring Road and cross the highland perimeter, connectivity disappears behind volcanic ridges. If you rely on streaming online map tiles from default apps, your screen will render a blank grey grid when you open your phone at a mountain road junction.

The KML, GPX and GeoJSON files live on your device, so the waypoints work with no signal. Downloading offline map tiles is a separate step inside your mapping app. You must store both the vector waypoint data and the underlying offline base map tiles in your phone's local storage while connected to Wi-Fi before heading into the interior.

The installation method depends entirely on your mapping software of choice. You can review step-by-step documentation for your specific mobile setup across our platform import guides:

Before purchasing comprehensive waypoint databases, test your hardware workflow at home. Download the free sample pack at the sample download page. The free sample at /sample is five real waypoints from the catalog, in the same format as the paid files, as one GPX file. No account, no expiry, nothing to install; leaving an email is optional. Import those five waypoints into your phone, disable mobile data and Wi-Fi by toggling Airplane Mode, and verify that the points, labels, and coordinates remain fully searchable on your offline base map.

Once you verify that your phone handles offline imports reliably, you can get the Complete Iceland Photo Map, which includes all 121 field-checked photography locations across the country in GPX, KML, and GeoJSON formats. The coordinates are published as an open CC-BY dataset. What is sold is the curation, the formats and the season and access notes—not secrecy.

Common F-road mistakes that cost photographers a shoot

Field experience reveals consistent patterns among photographers who lose shooting sessions or damage their vehicles in the Icelandic interior. Avoiding these five operational mistakes will protect your portfolio and your gear:

Assuming all 4x4 vehicles are legal for F-roads represents a frequent error. Travellers often arrive at a car rental desk, accept keys to an all-wheel-drive crossover, and assume they can drive to Landmannalaugar. When they reach the gravel junction, road signs explicitly display the 4WD requirement. Rental vehicle tracking units log location data; taking an unapproved vehicle onto an F-road triggers automatic notification to the rental provider, resulting in heavy fines regardless of whether damage occurred.

Planning an early-season highland itinerary without monitoring opening schedules leads to ruined plans. Booking accommodations near the highlands in late May or early June with the expectation of driving F208 or F88 is gambling against physics. If the subsoil remains saturated, Vegagerðin posts physical barrier gates across the roads. Attempting to bypass these gates constitutes a serious criminal offence carrying massive fines.

Underestimating drive duration causes photographers to arrive long after the prime light window has passed. A driver comfortable with doing 90 km/h on paved tarmac assumes a 50 km highland stretch will take 40 minutes. On an F-road filled with washboard ridges, sharp volcanic rocks, and cautious river crossings, that same 50 km stretch requires two hours. Photographers who fail to factor in this reduced pace arrive at their target viewpoint with the light flat, harsh, or gone.

Relying on connected cloud mapping applications guarantees navigation failure. Opening a mapping app in the middle of the Fjallabak reserve only to find an un-cached, low-resolution grey screen leaves you guessing at fork junctions. F-roads branch frequently into private farm tracks or emergency routes. Without cached vector waypoints stored directly in local device storage, identifying the correct turnoff becomes impossible.

Failing to account for rising river levels strands vehicles in the interior. A river that is easy to cross at 10:00 under cloud cover can become an impassable torrent by 16:00 if direct sun accelerates glacial melt or heavy rainfall hits the surrounding peaks. Assess downstream water marks on river boulders before crossing. If the water has risen significantly while you were hiking and shooting, do not force a crossing on the way out. Wait for the flow to subside or contact highland rangers for guidance.

Frequently asked questions

What are f roads in iceland?

F-roads are Iceland's interior mountain and highland tracks, indicated by an "F" preceding the route number (such as F208, F26, or F88). They run through unpaved, mountainous interior terrain and are legally restricted to four-wheel-drive (4WD) vehicles. They remain closed through winter and spring, opening only for a brief summer window.

Can you drive an F-road in Iceland in a 2WD rental car?

No. Under Icelandic traffic law, driving a 2WD vehicle on an F-road is strictly illegal. Doing so breaches standard car rental contracts, automatically invalidates vehicle insurance policies, and exposes the driver to severe administrative fines and substantial out-of-pocket recovery costs if the car becomes stuck or damaged.

When do Iceland's F-roads usually open and close?

Highland F-roads typically open between mid-June and early July, depending on how quickly winter snow melts and how fast wet subsoils dry out. Opening dates are decided road by road by Vegagerðin. Most F-roads close for the winter season between mid-September and early October as freezing temperatures and heavy snow return to the interior.

Do F-roads in Iceland have river crossings?

Yes, many major F-roads cross unbridged glacial and spring-fed rivers. These crossings vary from minor, shallow streams over firm gravel to deep, volatile glacial torrents with shifting channels and large boulders. Crossing rivers requires a high-clearance 4WD vehicle, proper low-range driving technique, and careful assessment of water depth and current speed before entering.

How do I check whether a specific F-road is open right now?

You can check the operational status of any road in Iceland by consulting the official Road and Coastal Administration website at road.is or calling their telephone service at 1777. The site provides map layers showing which roads are open, impassable (ófært), or closed for environmental protection (akstur bannaður). The files carry season and access notes, not live conditions. Check vedur.is and road.is for current weather and road status.

Decide the vehicle question before you decide the shot list

F-roads unlock dramatic volcanic, geothermal, and glacial landscapes, but they impose strict legal, temporal, and mechanical boundaries. The road classification dictates the vehicle you must rent, while seasonal melting cycles dictate the calendar window when those routes are physically accessible. Planning your photography route without confirming your vehicle's legal clearance and offline map readiness leads to missed shooting windows and voided insurance coverage.

Before finalizing your highland itinerary, verify road conditions for your travel dates on road.is, review your rental agreement to confirm your vehicle is explicitly permitted on numbered F-roads, and install your waypoint files so they operate independently of cellular coverage.

Start with the free sample at /sample (five real waypoints as one GPX file, no account required) and confirm they load on your phone before you commit to a highland route. When the route is set, the Complete map is $29 for all 121 locations in GPX, KML and GeoJSON.
