Iceland Ring Road F-Roads Circuit – Iceland
Highland desert crossing through volcanic wasteland
The F-roads of Iceland’s interior slice through landscapes that look like Mars with a weather problem. F35 Kjölur route runs 170 kilometers between Gullfoss and Akureyri, crossing the highland desert between Langjökull and Hofsjökull glaciers, while F26 Sprengisandur covers 200 kilometers from Goðafoss to the southern highlands. These routes ford unbridged glacial rivers like Þjórsá and pass active geothermal areas where steam vents remind you this island is still being born.
This is serious 4×4 territory requiring modified vehicles with snorkels, recovery gear, and multiple spare tires. River crossings can be waist-deep and change daily with glacial melt. Only passable June through September, with July-August being prime season. No permits needed but inform Icelandic search and rescue of your route. Fuel stations are 200+ kilometers apart in the interior. Wild camping is legal and necessary – bring cold-weather gear even in summer. This is Iceland’s version of crossing the Empty Quarter, where mechanical failure means helicopter rescue.

Frequently asked questions
Can a stock Land Cruiser or 4Runner run this, or do I actually need a snorkel?
A snorkel is mandatory, not optional — the glacial river crossings can hit 60–80cm without warning, and water temp is near freezing so there's zero margin for a hydrolocked engine. High clearance modified 4WD minimum; a stock rig will get swallowed on the F26 Sprengisandur crossings. Locals run heavily modded Defenders and Hiluxes for a reason.
When do the F-roads actually open and can I push it into late September?
The Icelandic Road Administration (road.is) typically opens F35 Kjölur in late May to early June and F26 Sprengisandur closer to late June — check road.is before you go because it changes year to year. Late September is a gamble; early snowfall and rising river levels from autumn melt have trapped rigs before. June through August is the reliable window.
Do I need permits or pay fees to drive the F-roads interior?
No permit or fee is required to drive the F-roads themselves, but dispersed camping in the highland interior falls under Icelandic Environment Agency rules — camp at designated highland huts or established campsites where possible, and follow Leave No Trace strictly as the volcanic soil takes decades to recover from vehicle or foot traffic.
What's the hardest section and what should I actually expect?
The F26 Sprengisandur is the more punishing of the two routes — it's a 200km slog across black sand desert with multiple unbridged glacial river crossings where depth and current change daily based on melt. You'll cross rivers with no markers, no bridges, and no cell service to call for help if you highcenter or flood an engine. Walk every crossing on foot before you drive it.
Where do I fuel up before heading into the interior — is 230 miles on one tank realistic?
Fuel up in Reykjavik and top off in Selfoss or Varmahlíð depending on your entry point — there is no fuel in the highland interior for the entire 370km route. Carry a minimum 20–30L of spare fuel; a heavily loaded rig crawling river crossings and soft sand will burn significantly more than highway figures suggest.
