Carreteras F de Islandia
Guía completa de las carreteras de montaña de Islandia — qué vehículo necesitas, cómo cruzar ríos, cuándo abren las carreteras y todas las rutas principales.
¿Qué son las carreteras F?
Las carreteras F (fjallvegir — "caminos de montaña") son las rutas de tierra de las tierras altas de Islandia. Solo están abiertas en verano, generalmente de finales de junio a septiembre, según el deshielo y las condiciones meteorológicas.
Todas las carreteras que comienzan con F requieren un vehículo 4x4 por ley. Conducir por una carretera F en un coche 2WD estándar es ilegal e invalida tu seguro de alquiler — serás personalmente responsable de cualquier daño, que puede superar 1.000.000 ISK (€7.000+).
Las carreteras F pueden incluir cruces de ríos profundos sin puentes, descensos empinados, grava suelta, baches y cambios repentinos de clima. ¿La recompensa? Acceso a los paisajes más extraordinarios de Islandia — montañas de riolita, calderas volcánicas y campos geotermales únicos en la Tierra.
Antes de conducir por cualquier carretera F
- ⚠Consulta el estado de las carreteras en road.is el día del viaje — pueden cerrarse de noche
- ⚠Registra tu ruta en safetravel.is para que los equipos de rescate conozcan tu plan
- ⚠Comprueba el pronóstico en vedur.is — no entres con alertas naranja o roja
- ⚠Asegúrate de que tu vehículo sea 4WD — verifica que el contrato de alquiler cubra las carreteras F
- ⚠Lleva suficiente combustible — no hay gasolineras en las tierras altas

Kjölur Route
EasyThe most accessible highland route, running between Gullfoss and Blönduós past Hveravellir geothermal area. No major river fords. Best for first-time highland drivers.
Landmannalaugar — North approach
ModerateNorthern access to Landmannalaugar from the Sprengisandur direction. Fewer river crossings than the southern approach.
Landmannalaugar — South approach
DifficultMost popular access route to Landmannalaugar from the south. Includes the Krossá river and several other fords that can be challenging after rain.
Askja Route
DifficultRemote volcanic route to Askja caldera from Mývatn. Includes the famous Lindaá river crossing which can be waist-deep in meltwater season. One of Iceland's most demanding drives.
Sprengisandur
ChallengingIceland's great north-south highland crossing over a bleak lava desert between the Vatnajökull and Hofsjökull glaciers. No services at all. Fuel and supplies must be carried.
Landmannaleið
ModerateAlternative access to Landmannalaugar from the west, crossing the Tungnaá glacier river. More scenic than F208 south but equally challenging.
Þórsmörk Route
DifficultShort but demanding route to Þórsmörk valley. The last 10 km involve multiple glacial river crossings that can be extremely hazardous. Highland buses are recommended.
¿Puedo conducir por esta carretera?
La pregunta más frecuente sobre las carreteras F. Aquí un resumen claro por tipo de vehículo.
Toyota Yaris / small car
2WD city car✗ NoNot permitted on any F-road. Insurance void. Rental companies will charge full cost of any damage.
Toyota RAV4 / Dacia Duster
Small 4×4 SUV⚠ DependeFine for F35 Kjölur and F208 north. Can struggle on deeper river crossings (F88, F249). Check ground clearance and rental agreement.
Toyota Land Cruiser / Ford Ranger
Large 4×4 / high clearance✓ SíSuitable for all F-roads including F88 and F249. Ideal for river crossings. Most common rental for highland travel.
Suzuki Jimny
Small 4×4⚠ DependeHigh clearance and capable off-road. Good for most F-roads but small — not for very deep rivers. Very popular rental.
Standard campervan
2WD campervan✗ NoNot permitted on F-roads. Standard campervans are 2WD and have no ground clearance. Must stay on paved roads.
4×4 campervan
4WD campervan⚠ DependePermitted on most F-roads but check your rental agreement — many prohibit river crossings. Long wheelbase limits access to F249 and F88.
Guía de cruces de ríos
Los cruces de ríos son la parte más peligrosa de conducir por carreteras F. La profundidad y la corriente pueden cambiar en horas — el deshielo glaciar alcanza su pico por la tarde.

Para y cruza a pie primero
Never drive in without checking on foot. Wade across to feel depth, current and the bottom surface. If it's above your knee, it may be too deep for your vehicle.
Cruza por el punto más ancho
Water spreads out at the widest section, making it shallower and the current weaker. Avoid narrow channels where water runs fast and deep.
Espera el momento del día adecuado
Glacial rivers rise in the afternoon as melt increases with daytime heat. Cross in the morning when levels are at their lowest.
Usa marcha corta y mantén velocidad constante
Select 4WD low range. Enter at an angle upstream. Keep a constant speed — never accelerate suddenly or you may stall with water in the engine.
Si el motor se apaga: no lo arranques de inmediato
If the engine stalls in water, do not try to restart — you risk hydrolocking the engine. Wait for rescue. Stay in the vehicle if there is a current risk.
Si tienes dudas: da la vuelta
There is no route in Iceland that is worth risking your life for. Recovery costs 200,000–500,000 ISK minimum. Turn around and try again later or choose an alternative route.
Advertencia sobre el seguro
Casi todos los contratos de alquiler en Islandia excluyen explícitamente los cruces de ríos de todos los niveles de seguro. Si tu vehículo resulta dañado o arrastrado, eres totalmente responsable. Solo el rescate cuesta 200.000–500.000 ISK; los daños al vehículo pueden ser 1.000.000 ISK o más.
Fechas de apertura de las carreteras F

| Carretera | Apertura típica | Notas |
|---|---|---|
| F35 Kjölur | Early June | Most reliable opening. Often first highland road to open. |
| F208 (North) | Mid-June | Depends on snow melt. Check road.is before departure. |
| F208 (South) | Late June – July | River levels highest in June. July safer for crossings. |
| F225 | Late June | Tungnaá river level depends on glacier melt. |
| F88 Askja | Late June – July | One of the last to open. Verify on road.is. |
| F249 Þórsmörk | Late June | Rivers can be dangerous even after opening — buses recommended. |
| F26 Sprengisandur | July | Last major road to open. Can close again in bad weather. |

Preguntas frecuentes
Todo lo que los viajeros preguntan sobre las carreteras F — respondido con honestidad.
Are F-roads dangerous?+
They can be. F-roads are unsurfaced mountain roads with no guardrails, steep drops and river crossings. Every year dozens of vehicles get damaged or stranded. With the right vehicle, preparation and respect for conditions, they are manageable — but never take them lightly.
Do rental cars cover F-road driving?+
Most rental companies permit 4×4 vehicles on F-roads but exclude river crossings from their insurance. If your vehicle is damaged in a river crossing, you are typically liable for the full cost (often 500,000–1,500,000 ISK). Always read the rental agreement carefully and consider purchasing extra protection.
What is the easiest F-road in Iceland?+
F35 Kjölur is widely considered the easiest major highland route. It runs north-south through the interior with no major river crossings, is usually the first to open (early June) and is suitable for most competent 4×4 drivers.
Can I drive F-roads in September?+
Some F-roads remain open in September, but conditions deteriorate and closures can happen with little warning. F35 typically stays open until mid-September. F88 and F26 may close earlier. Always check road.is on the day of travel. First snowfall can close roads overnight.
Do I need a 4x4 for all F-roads?+
Yes. By Icelandic law, all roads beginning with 'F' require a 4-wheel-drive vehicle. Driving on F-roads in a 2WD vehicle invalidates your insurance and violates road law. Even if conditions look fine, you will not be covered for any damage.
Can campervans drive F-roads?+
Only 4×4 campervans are permitted, and even then most rental companies restrict them from river crossings. Standard 2WD campervans cannot legally enter F-roads. For highland camping, consider parking a 4×4 and using highland buses for Þórsmörk and Landmannalaugar.
Are river crossings covered by insurance?+
Usually not. Most rental agreements explicitly exclude river crossings from all insurance cover — including the most expensive Super CDW packages. If your vehicle is swept away or flooded, you pay. The only exception is some specialist expedition rental companies.
When do F-roads open?+
F35 Kjölur typically opens in early June. Most other major routes open late June to July depending on snowmelt. F88 (Askja) and F26 (Sprengisandur) are often last, opening in July. Dates vary significantly year to year — always check road.is before travel.
