F333 (Haukadalsvegur): Driving the unpaved track near Geysir
The F333, also known as Haukadalsvegur, is a high mountain track located in the Southern Region of Iceland. This technical route serves as a link between Road 35 and the F-roads in Iceland, specifically connecting toward the F338. Starting near the popular Geysir geothermal area, the road quickly transitions into a rough Highlands track characterized by large rocks and unmaintained surfaces.

Where is the F333 Haukadalsvegur road located?
The F333 Haukadalsvegur runs north from the Haukadalur valley into the central Highlands. After passing the Haukadalskirkja Church, the track enters a sparse wooded area before climbing into a lunar volcanic landscape. This is a high-fatigue route where the roadbed is shaped by the powerlines it follows. There are no services or inhabitants along the route, and mobile coverage is non-existent once you leave the vicinity of Road 35.
Is a 4x4 mandatory for the F333 Haukadalsvegur?
Yes. Driving the F333 Haukadalsvegur in a small passenger car is irresponsible and dangerous. The track is in very bad condition, featuring large boulders, many deep ruts, and oversized potholes. A 4x4 vehicle with very high ground clearance is required to clear the irregular volcanic surface. The road is extremely bumpy, and the mechanical stress on the vehicle's suspension is constant throughout the climb toward the F338 junction.
How dangerous are the river crossings on the F333 Haukadalsvegur?
The F333 Haukadalsvegur requires crossing a small river located a few kilometers north of the Haukadalskirkja Church. While often shallow, this unbridged crossing can become treacherous after heavy rain. You must check the water depth and the position of submerged boulders before attempting to ford. Standard rental insurance does not cover engine damage caused by water intake, making it essential to have experience in glacial river crossings before driving the F333 Haukadalsvegur.
When is the F333 Haukadalsvegur road open?
The F333 Haukadalsvegur is only open during the summer months, typically between late June and early September. For the rest of the year, the track is totally impassable due to snow and deep mud from the spring thaw. Even in summer, it is not recommended to drive this track unaccompanied or during the dark, as the lack of lighting makes it impossible to judge the depth of the ruts or the flow of the river crossing.
What mechanical prep is needed for the F333 Haukadalsvegur?
Before leaving the paved Road 35, verify your 4WD system and tire condition. The sharp rocks on the F333 Haukadalsvegur can easily damage tires, so a full-size spare is mandatory. Check all underbody bolts and the integrity of your suspension, as the high-vibration environment will punish the vehicle. Ensure you carry recovery gear and extra water, as passing traffic is rare and professional mechanical assistance in this sector of the Highlands is slow and expensive.
