Route 1 between Selfoss and Höfn has no mountain passes, which is exactly why people underestimate it. It is about 400 km of coast road across open glacial sand, with the busiest stops in the country strung along it. This is what the road is like, what shuts it, and how long the drive really takes.

Selfoss to Höfn is roughly 400 km of Route 1 without a single mountain pass, and that fact causes most of the trouble: people see a flat coastal road and plan it as a day out. It is flat because it crosses glacial outwash plains — the most wind-exposed ground in the country.
The first stretch, Selfoss through Hella to Hvolsvöllur, is ordinary farmland: two lanes, 90 km/h, and some of the more heavily policed road in Iceland. East of Hvolsvöllur it runs under the Eyjafjöll cliffs past Seljalandsfoss and Skógafoss, crosses Sólheimasandur, then climbs the shoulder of the headland and drops steeply into Vík í Mýrdal.
East of Vík the character changes. Mýrdalssandur is a black sand plain running south from under Mýrdalsjökull, with nowhere to shelter. Then come Eldhraun, the moss-covered lava field left by the Laki eruption of 1783–84, and the service village of Kirkjubæjarklaustur. Beyond the cliff of Lómagnúpur the road crosses Skeiðarársandur, Iceland's largest outwash plain and the last gap in the Ring Road, bridged in 1974. Then Skaftafell and Freysnes under Öræfajökull, Fjallsárlón and Jökulsárlón on Breiðamerkursandur, and the farmland of Suðursveit and Mýrar. Höfn itself is off Route 1 — you turn onto Route 99 for the last few kilometres.
Most of the single-lane bridges left on Route 1 are between Vík and Höfn. Whoever is closer goes first; if in doubt, stop and wait — and never stop on a bridge for the view.
Non-stop, Selfoss to Höfn is around five hours, but nobody drives it that way; the reason to be here stands beside the road. Treat these figures as a planning floor: give the coast two days eastbound, a night in Vík or Kirkjubæjarklaustur, a night in Höfn.
| Leg | Approx. distance | Non-stop | Realistic with stops |
|---|---|---|---|
| Selfoss – Hvolsvöllur | ~50 km | 40 min | 1 h |
| Hvolsvöllur – Vík | ~80 km | 1 h | 3–4 h (Seljalandsfoss, Skógafoss, Dyrhólaey) |
| Vík – Kirkjubæjarklaustur | ~70 km | 50 min | 1.5–2 h (Fjaðrárgljúfur) |
| Kirkjubæjarklaustur – Skaftafell | ~70 km | 50 min | 1–1.5 h |
| Skaftafell – Jökulsárlón | ~55 km | 40 min | 2 h+ |
| Jökulsárlón – Höfn | ~80 km | 1 h | 1.5 h |
In winter, add a third to every figure and work backwards from daylight: December gives four or five usable hours, and the sands in the dark with drifting snow are a different job from the sands at noon.
The South Coast has no icy hairpins. It has four things that catch people out instead.
Two smaller ones. Sand and ash damage is normally excluded from standard rental cover and sold as an add-on, and wind damage to doors is usually excluded too — see our notes on Iceland car rental insurance. And from Skaftafell east, reindeer graze the lowlands in winter — the animal on the verge near Höfn may not be a sheep.
Route 1 along the South Coast is among the last roads in Iceland to shut; the side roads go first. The mountain tracks are gone from autumn — the Þórsmörk road with its unbridged rivers, the Fjallabak routes, anything marked with an F — then the small roads to viewpoints and glacier snouts. The Dyrhólaey road also closes at times for reasons unrelated to weather.
When Route 1 does close here, it is almost always wind, drifting snow or whiteout rather than snow depth. Mýrdalssandur and the open sands around Skeiðarársandur go first, then the Markarfljót flats east of Hvolsvöllur. Watch for ófært (impassable) and lokað (closed) on the map, and treat þungfært (heavy going) as a reason to wait rather than a challenge.
There is no detour — sea on one side, ice cap on the other, and the highland routes shut all winter. If Mýrdalssandur closes while you are in Vík, you are staying in Vík; the other way round the island to Höfn is well over 1,000 km and often worse weather. Check road conditions before each leg rather than each morning, ring 1777 if the map is ambiguous, 112 in an emergency. Most closures last hours, not days — one slack day in a winter plan makes the problem disappear.
Fuel is easy in the west, thin in the east. Selfoss, Hella and Hvolsvöllur are well served; after that the useful stops are Vík, Kirkjubæjarklaustur, Freysnes near Skaftafell, and Höfn. The stretch from Kirkjubæjarklaustur past Freysnes to Höfn is well over 100 km of sand and farmland with very little between. Fill up at Vík and again at Kirkjubæjarklaustur and you will never think about it. Many pumps are unstaffed and card-only, so carry a card with a PIN.
Beds cluster in the same places. Hella and Hvolsvöllur suit a first night out of Reykjavík. Vík is the natural mid-point and books out earliest in summer; Kirkjubæjarklaustur is smaller and quieter. Between there and Höfn the options are scattered farms and guesthouses around Öræfi, Hof and Fagurhólsmýri — do not arrive at Jökulsárlón at nine in the evening assuming something will turn up. Höfn is a proper town and the obvious base for the southeast corner.
Summer, roughly June to August, is easy driving and hard parking. The road is clear, the light lasts all evening, and the car parks at Seljalandsfoss, Skógafoss and Jökulsárlón are full from mid-morning. Sheep are loose on the verges, and wind and sand can still shut a section on a bright day.
September and October are the sweet spot: fewer cars, the F-roads closing behind you, the first autumn storms arriving. Winter tyres are required from roughly November to April, and by then wind and daylight run the schedule: winter storm systems cross this coast every few days, and each may take Route 1 out east of Vík for part of a day. Our guidance on winter driving in Iceland applies in full, with one local addition: the sands offer no shelter, so if conditions turn, stop in a settlement.
April and May bring the road back, but the ground stays wet and the wind stays strong. Meltwater is high, glacier tracks are soft, and the highland routes will not open until around mid-June at the earliest. The main road is fine; the sideshows are not yet.
You can — it is roughly 750 km return and nine or ten hours of driving before you stop anywhere. Doable in summer with two drivers; in winter, with short daylight and possible closures on Mýrdalssandur, a poor plan. Stay a night in Vík, Kirkjubæjarklaustur or Höfn instead.
Not for Route 1 itself — it is paved throughout and a two-wheel-drive car on proper winter tyres handles it. A 4x4 helps in crosswinds and on unpaved side roads and is required for any F-road, but it does nothing about wind closures, which are what stop you here.
Wind. Gusts across the sands can blow a high-sided vehicle off the carriageway, and dry sand cuts visibility to nothing. Wind and sand closures happen outside winter too.
Only well back from the water. Sneaker waves run far higher than the sea state suggests and have killed visitors repeatedly; stay above the wet sand, keep watching the sea, and avoid the basalt columns when waves wash their base.
You wait and you tell the accommodation — there is no bypass. Closures usually clear within hours once a front passes, so have somewhere to sit in Vík or Kirkjubæjarklaustur and a flexible booking at the far end.
