F66 Kollafjarðarheiði: The Westfjords Highland Crossing

The F66 Kollafjarðarheiði stands as one of Iceland's most dramatic highland crossings, carving a rugged 43-kilometre path across the windswept interior of the Westfjords peninsula. This challenging mountain road connects the villages of Patreksfjörður in the south with Tálknafjörður in the north, offering intrepid travellers a genuine taste of Iceland's untamed highland wilderness far from the well-trodden Ring Road.

Unlike the more famous highland routes of central Iceland, F66 receives relatively few visitors, making it a prized route for those seeking solitude amongst some of the country's most ancient landscapes. The road traverses terrain that predates Iceland's volcanic activity, crossing mountains formed over 16 million years ago during the earliest phases of the island's geological formation.

The Highland Traverse

The F66 begins its ascent just 3 kilometres east of Patreksfjörður, immediately leaving civilisation behind as it climbs into the Kollafjarðarheiði plateau. The initial 8 kilometres wind steadily upward through increasingly barren terrain, with the road surface transitioning from gravel to rough highland track.

At approximately 11 kilometres from Patreksfjörður, the route crosses the plateau's highest point at 519 metres above sea level. From this exposed summit, the landscape opens into a vast highland desert punctuated by ancient peaks and deep valleys carved by glacial action during the last ice age. On clear days, views extend across the entire Westfjords peninsula, with glimpses of the Denmark Strait to the west and the dramatic coastline of Arnarfjörður to the southeast.

The northern descent proves equally challenging, dropping 400 metres over 15 kilometres through a series of steep switchbacks and river crossings. Several unbridged streams require careful navigation, particularly the crossing at Kollafjarðardalur, where spring snowmelt can create treacherous conditions well into July.

Geological Significance

The Kollafjarðarheiði plateau represents some of Iceland's oldest exposed bedrock, consisting primarily of basalt flows from the Tertiary period. These ancient lava formations, now heavily weathered and oxidised to distinctive rust-red and yellow hues, predate the active volcanic zones that dominate Iceland's interior.

The highland's most striking geological feature is the extensive plateau basalt formation, which extends unbroken for nearly 20 kilometres. This flat-topped terrain, carved by glacial action and shaped by millions of years of weathering, creates an otherworldly landscape that bears little resemblance to Iceland's more familiar volcanic regions.

Scattered across the plateau, travellers encounter numerous kettle lakes formed during the retreat of the Weichselian ice sheet approximately 10,000 years ago. These small, circular bodies of water provide crucial habitat for arctic char and serve as stopping points for migratory birds crossing between Greenland and Europe.

Driving Conditions and Vehicle Requirements

F66 demands a capable 4WD vehicle with high ground clearance. The route includes several river crossings, loose gravel sections, and steep gradients that defeat most rental cars. Highland driving experience is strongly recommended, as the road receives minimal maintenance and conditions can deteriorate rapidly.

The most challenging section lies between kilometres 18-25, where the track crosses several seasonal streams without bridges. During spring thaw (typically May through early July), these crossings can become impassable even for experienced highland drivers. The largest crossing, at Kollafjarðardalur, requires particular caution as water levels can rise dramatically within hours during heavy rainfall.

Road conditions vary significantly throughout the season. Early summer crossings (June-July) often encounter snow patches and muddy conditions from snowmelt. August typically provides the most stable conditions, whilst September brings renewed weather instability as highland storms increase in frequency and intensity.

Weather and Seasonal Access

The F66 typically opens for highland-capable vehicles in mid-to-late June, though exact timing depends on snowpack and spring weather conditions. The Icelandic Road Administration (Vegagerðin) maintains current road status information, but conditions can change rapidly without warning.

Highland weather proves notoriously unpredictable, with visibility dropping to near zero within minutes as fog and low clouds roll across the plateau. Temperatures can plummet 15-20 degrees Celsius from sea level, making warm clothing essential even during summer crossings. Wind speeds regularly exceed 80 km/h on the exposed plateau, creating challenging driving conditions.

The optimal crossing window runs from late July through mid-September, when daylight hours remain long and weather patterns show relative stability. Early season attempts (June-July) risk encountering impassable snow drifts, whilst late season crossings (October onwards) face increasingly severe weather and potential early snowfall.

Planning Your Crossing

Allow 3-4 hours for the complete crossing under good conditions, though weather delays can extend journey times significantly. Fuel consumption increases substantially during highland driving, so ensure tanks are completely full before departure. Neither Patreksfjörður nor Tálknafjörður offer recovery services for disabled vehicles on the highland section.

Essential equipment includes emergency food supplies, warm clothing, emergency shelter, and communication devices. Mobile phone coverage remains sporadic to non-existent across most of the route, making satellite communicators advisable for solo travellers.

The nearest accommodation lies in either Patreksfjörður or Tálknafjörður, both offering guesthouses with rates around 15,000-20,000 ISK (€100-135) per night during summer months. Wild camping is permitted on the highland section, though exposed conditions make this suitable only for experienced highland campers with appropriate gear.

Conservation and Respect

The Kollafjarðarheiði ecosystem remains fragile despite its harsh appearance. Moss and lichen communities, some centuries old, recover extremely slowly from vehicle damage. Stay strictly on established tracks, avoid creating new routes around obstacles, and pack out all waste.

This ancient landscape offers modern travellers a rare glimpse into Iceland's geological past whilst providing an authentic highland adventure far from tourist crowds. The F66 rewards those who approach it with proper preparation, respect, and patience with one of the Westfjords' most memorable wilderness experiences.
