Planning an Extended Highland Loop: Combining Multiple F-Roads

Planning an Extended Highland Loop: Combining Multiple F-Roads

Iceland's highland F-roads offer some of the most spectacular and challenging driving experiences on Earth. For adventurous travellers seeking to explore the island's remote interior, combining multiple F-roads into an extended highland loop creates an unforgettable journey through volcanic deserts, steaming geothermal fields, and pristine wilderness areas inaccessible by conventional vehicles.

Essential Prerequisites

Before attempting any extended highland loop, ensure your vehicle meets the demands. A proper 4WD with high ground clearance is mandatory—not merely recommended. River crossings, sharp volcanic rock, and deep sand sections will test both vehicle and driver. Most rental companies offering F-road capable vehicles require drivers to be at least 23 years old and hold valid insurance covering highland driving.

Stock up on essentials before departing Reykjavík: spare tyres (carry two), emergency food for at least three days, camping equipment, first aid supplies, and navigation tools. Mobile coverage disappears entirely in many highland areas, making GPS devices or detailed topographic maps essential. Register your travel plans with SafeTravel.is and carry an emergency beacon if possible.

The Classic Kjölur-Sprengisandur Circuit

The most accessible extended loop combines F35 (Kjölur) and F26 (Sprengisandur), creating a 580km circuit that showcases Iceland's highland diversity without requiring extreme technical driving skills.

Starting from Reykjavík, take Route 1 east to Gullfoss, then connect to F35 northbound. The Kjölur route stretches 170km through the interior, passing between the Langjökull and Hofsjökull glaciers. Key stops include Hveravellir geothermal area at kilometre 100, where natural hot springs provide respite from highland winds. The original geothermal pool maintains a constant 37°C, whilst newer pools reach 40°C.

At the northern end, F35 meets Route 1 near Blönduós. Head east along the Ring Road for 180km to Varmahlíð, then south on Route 752 to access F26 (Sprengisandur). This 200km highland crossing runs between Hofsjökull and Vatnajökull glaciers, offering stark volcanic landscapes and challenging river fords.

The Sprengisandur's most demanding section lies between kilometres 40-80, where multiple river crossings require careful assessment. The Tungnaá crossing at kilometre 65 particularly demands attention—test depth with a walking stick before committing your vehicle.

Advanced Route: The Landmannalaugar Triangle

Experienced highland drivers should consider the challenging triangle connecting F208 (Landmannalaugar), F210 (interior), and F225 (Landmannaleið). This 420km loop demands superior driving skills but rewards with Iceland's most dramatic highland scenery.

Begin at Selfoss, taking Route 26 and then F26 southwest to connect with F208. The 55km approach to Landmannalaugar includes the notorious Frostastaðavatn crossing—a 1.2km lake transit that eliminates many vehicles annually. Water depth varies seasonally but typically ranges 0.8-1.2 metres. Maintain steady momentum and never stop mid-crossing.

From Landmannalaugar's basecamp, continue northeast on F208 toward Landmannaleiðir hut, then connect to F210. This interior route parallels the western edge of Vatnajökull, passing through the Vonarskarð saddle at 700m elevation. Weather conditions change rapidly here—summer snowfall occurs regularly.

The F225 western leg completes the triangle, descending through Þórsmörk's glacial valleys. Multiple river crossings characterise this section, with the Krossá River crossing being particularly technical. Local guides recommend crossing during morning hours when glacial melt is minimal.

The Ultimate Challenge: Askja-Holuhraun Expedition

For the most adventurous, combining F88 (Askja route) with F910 (Holuhraun access) creates a demanding 480km expedition into Iceland's most active volcanic region. This route requires exceptional preparation and should only be attempted by experienced highland drivers travelling in convoy.

F88 begins near Mývatn, immediately challenging drivers with the Jökulsá á Fjöllum ford—a 200-metre wide glacial river with shifting channels. Beyond lies 85km of demanding terrain including the Öskjuleið pass and descent into Askja caldera. The route culminates at Víti crater, where a 15-minute walk reveals a spectacular explosion crater filled with milky blue geothermal water.

From Askja, F910 provides access toward Holuhraun, site of the spectacular 2014-2015 eruption that created 85 square kilometres of new lava. The road quality deteriorates significantly beyond the Drekagil hut, requiring constant vigilance for sharp lava fragments capable of shredding tyres.

Timing and Weather Considerations

Highland roads officially open between mid-June and mid-October, though conditions vary significantly. Early season (June-July) brings swollen rivers from glacial melt but offers midnight sun for extended driving hours. Peak season (July-August) provides optimal road conditions and weather stability. Late season (September-October) offers dramatic autumn colours but increasing weather unpredictability.

Always check current conditions at road.is before departure. Highland weather changes within hours—blue skies can transform into blinding sandstorms or unexpected snowfall even in summer. Carry warm clothing regardless of seasonal timing.

Accommodation and Resupply

Highland huts operated by Ferðafélag Íslands provide basic accommodation at key locations including Landmannalaugar, Hveravellir, and Askja. Book well in advance during peak season; beds cost 6,500 ISK (€45) per night. Many huts offer basic provisions, but prices exceed lowland costs by 40-60%.

Camping remains the most flexible option for extended loops. Designated camping areas exist at most major stops, typically charging 1,500 ISK (€10) per person. Wild camping is permitted but follow Leave No Trace principles strictly.

Safety Protocols

Extended highland loops demand rigorous safety protocols. Travel in convoy when possible—minimum two vehicles for remote routes like Askja. Establish regular check-in schedules with emergency contacts and stick to planned itineraries. River crossings claim several vehicles annually; when in doubt, don't attempt.

Emergency shelter exists at various highland locations, but rescue operations can require days in severe weather. Self-sufficiency isn't merely recommended—it's essential for survival in Iceland's unforgiving highland environment.

The highlands offer unparalleled wilderness experiences for properly prepared adventurers, but they equally punish complacency and poor preparation. Plan meticulously, prepare thoroughly, and Iceland's highland loops will provide memories lasting a lifetime.
