The Best F-Roads to Explore in Iceland with a Rental Van

Iceland’s rugged highlands and remote landscapes are best accessed via its famous F-roads—mountain roads that lead to some of the country’s most breathtaking destinations. If you're renting a van for your Icelandic adventure, these roads can take you deep into untouched wilderness, geothermal wonders, and otherworldly landscapes. However, driving F-roads requires preparation, the right vehicle, and an understanding of the risks, especially since rental car insurance does not cover water damage if you drown your car in a river crossing.

Let’s dive into some of the best F-roads to explore in Iceland and what you need to know before hitting the gravel!

1. F208, F224– The Road to Landmannalaugar

One of the most famous F-roads in Iceland, F208 leads to Landmannalaugar, a stunning geothermal area with colorful rhyolite mountains, hot springs, and incredible hiking trails. The journey there is a true adventure, featuring steep hills, lava fields, and river crossings.

What to Expect:

  • Starts from the south via F208 South or from the north via F26
  • Requires a high-clearance 4x4 due to rough terrain
  • River crossing
  • Hot spring reward at the end!

Pro Tip: If you're uncertain about river crossings, park before the last river and walk to Landmannalaugar. Many travelers do this to avoid getting stuck!

2. F35, F347 – The Road to Kerlingarfjöll

The F35, a scenic route connecting the southern Gulfoss area with northern Iceland, offers travelers a striking journey through Iceland’s rugged highlands. Along the way, this iconic road splits, with the F347 branching off to Kerlingarfjöll, a captivating geothermal mountain range, while the F35 continues its path through the Hveravellir area, renowned for its hot springs and dramatic landscapes.

This route doesn’t feature major river crossings, making it more accessible than some other highland roads. However, the road's quality can fluctuate depending on the season and the level of maintenance. Travelers should be prepared for some rough patches, especially as the section leading to the Kerlingarfjöll Highland Base has developed potholes over time due to increased traffic.
