What Are F-Roads?
F-roads are mountain tracks that lead into Iceland’s remote interior. Think gravel, rivers, steep hills and big views. They’re only open in summer, typically mid-June to mid-September, and you’re legally required to drive a 4x4 vehicle on them.
Driving a normal car here isn’t just risky, it’s illegal. If you try it, you’ll void your insurance and could get fined.

Why You Need a Real 4x4
