Iceland's Interior Roads Open

The F-roads into Iceland’s interior open for a short season, typically from late June into July, offering a narrow window to landscapes unlike the coastal ring. These are not ordinary roads. They demand a four-wheel-drive vehicle and a willingness to ford unbridged rivers, but they lead to places like Landmannalaugar, with its ochre rhyolite hills and hot springs, and the birch valley of Þórsmörk. This brief period around the summer solstice is when the country’s wild heart becomes accessible, a distinct experience from the popular sights along Route 1.

Landmannalaugar sits in a geothermal valley, its mountains streaked with colours of rust, green, and yellow, a result of the rhyolite rock. Here, hot springs provide a chance to bathe in the open air, surrounded by a landscape that feels ancient and raw. It is also the starting point for the Laugavegur trail, Iceland’s best-known multi-day hike, though a day trip can still offer a substantial walk through the unique terrain. The long daylight hours of June allow for late arrivals and extended explorations, with the sun barely dipping below the horizon.

At the far end of the Laugavegur trail lies Þórsmörk, a sheltered valley of birch woods nestled between glaciers. This area, too, is reachable by F-road and presents a fine day’s walking on its own. Both Landmannalaugar and Þórsmörk represent a different kind of Iceland trip, one that trades paved roads and easy access for rugged terrain and a sense of remoteness. The journey itself is part of the experience, requiring careful preparation and respect for the conditions.

The hard rule for these interior excursions is the vehicle. A two-wheel-drive hire car is not sufficient; four-wheel drive is a legal and practical requirement. Many F-roads involve river crossings, which are hazardous and typically not covered by standard insurance. It is crucial to check the official road authority’s F-road opening dates and daily conditions before setting out. These dates change year to year and can run weeks later than the calendar suggests, so a commitment made too early might find the way still closed. Never drive off marked tracks; the vegetation is fragile, and fines are applied.

Treat every river crossing as a decision, not a formality. If confidence is lacking, turning back is the correct choice. The rewards, however, are substantial: a day or two in the Highlands offers a profound sense of isolation and a visual spectacle that sets it apart from almost anywhere else. This window, open only for weeks either side of the solstice, is the reason serious returnees choose summer for their Iceland trips.
