F66, known as Kollafjarðarheiði, is a mountain road traversing the Westfjords region of Iceland. This 25-kilometer route connects the southern and northern parts of the Westfjords, running from Road 60 (Vestfjarðavegur) near Kollafjörður bay to Road 61 (Djúpvegur) near Ísafjörður bay.
F66 is an unpaved highland road, primarily composed of gravel and dirt surfaces. It is suitable only for 4x4 vehicles with high ground clearance due to its challenging terrain, which includes steep inclines and declines. Drivers should be prepared for narrow passages with vegetation encroaching on both sides and occasional boulders requiring careful navigation.
Travelers on F66 will encounter several unbridged river crossings, more akin to streams than substantial rivers. While these crossings are generally manageable, it is essential to assess water levels and current conditions before proceeding, as they can vary depending on recent weather patterns.
The route offers a unique perspective of the Westfjords' rugged landscape, characterized by its remote and stark beauty. Travelers can experience a sense of isolation and tranquility, with expansive views of the surrounding fjords and mountains. Historically, the Kollafjarðarheiði pass has been a significant connector between communities in the Westfjords, though it remains less traveled compared to other routes.
F66 is typically open during the summer months, from late June to early September, depending on weather conditions and maintenance schedules. There is no specific information on when the road reopens after winter closures, so travelers should consult local authorities or the Icelandic Road and Coastal Administration for current road statuses before planning their journey.
Traveling F66 offers an opportunity to experience one of Iceland's less frequented yet profoundly scenic routes. With proper preparation and respect for the challenging terrain, it can be a rewarding journey for those seeking solitude and natural beauty.
