F235 Langisjór: Iceland's Most Photogenic Highland Lake Road

The F235 Langisjór stands as perhaps Iceland's most spectacular highland F-road, delivering travellers to the ethereal shores of Langisjór lake whilst threading through some of the country's most pristine volcanic wilderness. This 45-kilometre mountain track transforms a simple journey into an expedition through geological time itself, culminating at a lake so perfectly formed it appears almost artificial in its symmetry.

The Route Overview

The F235 branches eastward from the F208 Fjallabak route, approximately 23 kilometres south of Landmannalaugar. This highland track requires a 4WD vehicle with substantial ground clearance—the route features numerous river crossings, loose volcanic gravel sections, and terrain that can challenge even experienced highland drivers. The entire journey from the F208 junction to Langisjór's shores covers 45 kilometres and typically requires 90 minutes to two hours of careful driving.

The road remains accessible only during the highland season, generally from late June through early September, though these dates fluctuate based on winter snowfall and spring thaw conditions. Before departure, check road conditions at road.is and consider the Highland Bus (bus 5) as an alternative, which operates scheduled services to Langisjór during peak summer months at 12,900 ISK (€85) per person for a day trip from Reykjavík.

Geological Wonders Along the Way

Torfajökull Volcanic System

The F235 traverses the heart of the Torfajökull volcanic system, Iceland's largest rhyolite volcanic complex. This 1,200-square-kilometre system represents one of Europe's most significant high-silica volcanic regions, creating the distinctive pale mountains and multicoloured rock formations that define this landscape.

The route passes through extensive rhyolite fields, where the pale, glassy volcanic rock creates an almost lunar landscape. These formations, dating primarily from the last glacial period between 11,000 and 130,000 years ago, showcase the violent interaction between fire and ice that shaped Iceland's highlands.

River Crossings and Volcanic Plains

Seven significant river crossings punctuate the journey, with the Tungnaá tributaries presenting the most challenging fords. These glacier-fed streams fluctuate dramatically with weather conditions and time of day—morning crossings typically prove easier as glacial melt reaches peak flow in afternoon hours.

Between crossings, the track traverses vast pumice plains created by explosive volcanic eruptions. The Hekla volcano, visible to the southwest throughout much of the journey, contributed significantly to these deposits during its numerous historical eruptions, most recently in 2000.

Langisjór: The Crown Jewel

The Lake's Formation

Langisjór stretches 20 kilometres in length whilst maintaining a remarkably consistent 2-kilometre width, creating the elongated shape that gives the lake its name—literally "Long Lake" in Icelandic. This extraordinary linear formation results from its position within a glacially carved valley, subsequently dammed by volcanic activity from the surrounding Torfajökull system.

At 670 metres above sea level, Langisjór ranks among Iceland's highest significant lakes. Its depth reaches 75 metres at the deepest point, with the lake containing an estimated 300 million cubic metres of water fed primarily by glacial melt from Vatnajökull's western outlets.

Photographic Paradise

The lake's photographic appeal stems from its perfect symmetry and the dramatic contrast between the dark water and pale rhyolite mountains that frame both shores. The most celebrated viewpoint sits at the road's terminus on the lake's northwestern shore, where a small parking area accommodates perhaps 20 vehicles.

Professional photographers particularly prize the pre-dawn hours when mirror-still conditions create perfect reflections of the surrounding peaks. The lake's north-south orientation means both sunrise and sunset light illuminate the water directly, whilst the pale volcanic mountains provide excellent contrast against Iceland's notoriously dramatic skies.

Wildlife and Wilderness

Despite the harsh highland environment, Langisjór supports surprising biodiversity. Arctic char thrive in the lake's cold, oxygen-rich waters, though fishing requires permits available through local angling associations at approximately 2,500 ISK (€17) per day.

Pink-footed geese utilise the lake during migration periods, particularly in late August and early September. The surrounding wetlands support dunlin, golden plover, and whimbrel, whilst reindeer occasionally graze the area's sparse highland vegetation during summer months.

Practical Considerations

Vehicle Requirements and Costs

Only vehicles with genuine 4WD capability and minimum 200mm ground clearance should attempt the F235. Rental companies typically charge premiums of 15,000-25,000 ISK (€100-165) per day for highland-capable vehicles, with comprehensive insurance adding another 8,000-12,000 ISK (€55-80) daily.

Petrol costs prove significant—budget approximately 8,000 ISK (€55) for the round trip from Reykjavík, plus emergency fuel reserves. The nearest petrol station sits 140 kilometres away at Hella, making fuel planning crucial.

Safety and Preparation

Weather conditions change rapidly in the highlands. Even summer temperatures rarely exceed 15°C, whilst sudden storms can bring snow at any time of year. Essential equipment includes warm clothing, waterproofs, emergency food supplies, and communication devices—mobile coverage remains non-existent throughout most of the route.

River crossings require particular caution. Test depth and current strength before committing to any ford, and never attempt crossings during heavy rain or rapid snow melt periods. If uncertain, wait for other vehicles or consider turning back.

Best Visiting Strategy

Plan overnight camping at Langisjór to maximise photographic opportunities—the designated camping area sits 500 metres from the main viewpoint and accommodates approximately 30 tents. Camping fees of 2,000 ISK (€13) per person apply, payable via the WC Service app or on-site collection boxes.

Early morning and late evening provide the finest conditions for both photography and wildlife observation. Midday winds frequently disturb the lake's surface, eliminating reflection photography opportunities whilst afternoon river levels peak, complicating the return journey's water crossings.

The F235 to Langisjór represents highland driving at its most rewarding—challenging enough to feel genuinely adventurous yet accessible to competent drivers with proper preparation. This remarkable route delivers one of Iceland's most spectacular and least crowded natural monuments, justifying every careful kilometre of the journey.
