Highlands and F-roads: what you need to know

The highlands are Iceland's interior: Vegagerðin, the Road and Coastal Administration, classes land more than 300 m above sea level as highland, often snow-covered well into summer ^[1]. Most highland routes are F-roads, rough tracks that open only for a short summer window. Here is what the official sources say about when they open, which cars they suit, river crossings and the checks to make before you go.

Status now: closed for winter (checked 25 October 2026)

Safetravel says F-roads are usually closed from mid-September until June or July; in that period they are closed or impassable for anyone not in a modified vehicle (superjeep), and the way to get there is to book one with an experienced driver ^[2]. Vegagerðin's own road-condition data, exported at 02:06 Iceland time (UTC) on 25 October 2026, showed this for the main highland routes ^[3]:

This is a snapshot, not a forecast. Status changes, and this page is not updated live: check umferdin.is (www.road.is redirects there) or call Vegagerðin's traffic service on 1777, open 24 hours ^{[4] [1]}. Road numbers in the table follow Vegagerðin's opening table ^[1].

F-road grades: F1, F2, F3

Vegagerðin grades highland tracks (landsvegir) in three types. All are tracks about 4 m wide, often lower than the land on either side, and often closed in winter because of snow and thaw mud ^[5]:

Safetravel adds that not every 4x4 suits every F-road: some suit a Dacia Duster or similar, others need a Toyota Land Cruiser or bigger, and some need a modified superjeep ^[2]. Rental terms also matter: one rental company's terms, for example, exclude F-roads unless the car is approved for them ^[6]. Read your contract and see our car rental guide.

When do the highland roads open?

Snow cover is the most important factor. Where a mountain road passes through a conservation area, it may stay closed until the whole area can withstand visitors, even if the road itself is clear ^[1]. In spring and early summer, while snow melts and the ground thaws, roads and vegetation are easily damaged, and the highland summer, the growing season for its sensitive vegetation, lasts only a month and a half ^[1].

Vegagerðin's opening dates, 2021–2025 ^[1]:

We leave out the F208 Eldgjá–Skaftártunga row: its published average (13 May) is earlier than every yearly date in the same row, so it looks like a typo ^[1]. Past dates do not predict next year's opening; we do not guess dates.

In spring and early summer, Vegagerðin and the Environmental and Food Agency publish maps showing where traffic on mountain tracks is banned because of thaw; all traffic in the shaded areas is prohibited until further notice ^{[1] [7]}. When we checked on 25 October 2026, the latest map for 2026 was no. 16, valid from 30 July 2026 ^[7]. The map only covers thaw closures, not snow or general road conditions, so check umferdin.is as well ^[7].

River crossings and insurance

Safetravel states that no insurance covers damage to a vehicle while crossing a river: the risk is always yours, and damage can cost thousands of euros or dollars ^[2]. Its advice ^[2]:

• Current and depth change constantly, and rivers often become impassable.
• If unsure, do not cross: turn around, or wait for other travellers.
• Plan your line first, drive very slowly in the lowest gear (low range), steadily, and do not change gear in the water.
• Angle downstream rather than against the current, and watch for big rocks under the surface.

The "unbridged rivers" road sign is most common on F-roads; Safetravel says such crossings are only suitable for bigger 4x4s ^[8]. More on what rental insurance typically excludes: car rental insurance.

Rules on and off the track

• Driving on F-roads and gravel roads is not off-road driving; leaving them is ^{[9] [10]}.
• Off-road driving is illegal and punishable by fines or imprisonment ^[11]. Drive slowly over obstacles on the track instead of going around them ^[11].
• Vegagerðin warns that the greatest spring damage comes from vehicles leaving the road to get around snowdrifts ^[1].
• "Lokað" means closed. A closed road is closed to all vehicles, including bicycles and motorcycles ^{[8] [10]}.
• Speed limits apply only in the best conditions; choose your speed for the road and weather ^[10].
• Google Maps and other map apps may not show closed or impassable roads ^[12].

Before a highland day

1. Is the road open? Check umferdin.is or call 1777 ^{[4] [5]}. Safetravel says this is the first thing to check ^[2].
2. Weather Forecasts and weather warnings from the Icelandic Met Office on vedur.is ^[13]; check conditions in the morning and again during the day ^[10].
3. Alerts Current alerts on safetravel.is ^[14]. Ask locally too: Safetravel suggests information centres, rangers and hut wardens ^[2].
4. Travel plan Leave one on safetravel.is with someone not on the trip who can react if you do not check in ^[15].
5. Car and contract Is your 4x4 suitable for this grade of road, and does your rental contract allow it ^{[5] [6]}?

Emergency: 112

Call 112 in any emergency, 24 hours a day. You can also use the 112 Iceland app or web chat; if calling 112 fails, try +354 599 0112 ^[16]. Report off-road driving you witness to the police on 112 or to rangers ^[11].

FAQ

Are the F-roads open now (late October)?

No, not in the normal sense. Safetravel says F-roads are usually closed from mid-September until June or July. On 25 October 2026 Vegagerðin's road-condition feed listed the main highland routes, including F208, F225, F210, F26, F206, F261 and F821, as impassable or not serviced, and Kjölur (road 35) as impassable between Kerlingarfjöll and Blönduvirkjun. Check umferdin.is for today's status. ^{[2] [3]}

When do the F-roads open?

There is no fixed date: snow cover decides. Vegagerðin's 2021–2025 averages range from 1 June (Kjölur, Gullfoss–Hveravellir) and 2 June (F208 Sigalda–Landmannalaugar) to 7 July (F210 Keldur–Hvanngil, F821). Past dates do not guarantee next year's opening. ^[1]

Does insurance cover river crossings?

Safetravel states that no insurance covers damage to a vehicle while crossing a river; the risk is always yours. ^[2]

Is driving an F-road off-road driving?

No. Driving on F-roads and gravel roads is not off-road driving; leaving them is, and off-road driving is illegal. ^{[9] [11]}
