A Brief History of Langisjor in Iceland

Langisjor remained a mystery for centuries. It wasn't until the mid-19th century that this stunning lake was discovered and documented, largely thanks to Iceland's first geologist, Þorvaldur Thoroddsen.

In the late 19th century, Thoroddsen explored the area and observed Langisjór from the summit of Sveinstindur. His exploration marked the first recorded observations of the lake and its surrounding landscape. Thoroddsen named both the lake and the mountain, choosing to honor his friend, a physician, by naming the peak after him.

The Geography and Formation of Langisjór

Langisjór, also known as Lake Langisjór, is a stunning glacial lake located in the Highlands of Iceland, within the renowned Vatnajökull National Park. Spanning around 27 square kilometers (10.4 square miles), the lake stretches approximately 20 kilometers (12.4 miles) long and 2 kilometers (1.2 miles) wide.

Positioned at an elevation of 670 meters (2,200 feet) above sea level, Langisjór is surrounded by dramatic mountain ranges, with Fögrufjöll to the south and Tungnarfjöll to the north. The name 'Langisjór' fittingly translates to 'long lake,' highlighting its elongated shape.

This breathtaking lake formed during the last Ice Age through a combination of subglacial volcanic eruptions and glacial erosion. 

These powerful forces sculpted the steep cliffs and rugged topography that define the area today. Langisjór's stunning beauty is matched by its remote and difficult accessibility, making it an ideal destination for those looking to escape the crowds and find solitude in the Icelandic Highlands.

Glacial Origins and Volcanic Influence

Langisjór owes its stunning beauty to both volcanic and glacial forces. During subglacial volcanic eruptions, intense heat melted parts of the overlying ice sheets, forming depressions that filled with meltwater, eventually creating the lake. Known for its exceptionally clear and pure waters, Langisjór is fed by nearby springs and streams.

The surrounding mountain ranges, Fögrufjöll and Tungnarfjöll, were shaped by similar volcanic activity and feature tuyas, which are mountains formed by lava erupting beneath the ice. Notable peaks include Sveinstindur, standing at 1,092 meters (3,583 feet), and Breiðbakur, which reaches 1,018 meters (3,340 feet), offering breathtaking views of the region.

How to Get to Langisjor in Iceland

Reaching Langisjor in Iceland requires navigating a rugged and remote route, but the breathtaking scenery makes every challenge worthwhile. To explore Langisjór, a high-clearance 4x4 vehicle is non-negotiable.

Regular cars simply cannot handle the rough terrain, river crossings, and steep tracks leading to the lake. We recommend using vehicles such as the Dacia Duster or the more robust Jeep Wrangler, both of which are perfect for tackling Iceland's challenging F-roads. Just remember before you set off to always check that the trail is open for travel from the Icelandic Road and Coastal Administration website.

Routes to Langisjór

There are two main routes you can take to reach Langisjor in Iceland, depending on where you're coming from:

  1. From Vik or Kirkjubæjarklaustur

Take F208 south and turn right onto F235.

  1. From Landmannalaugar

Follow F208 and turn left onto F235. This route offers a more scenic but slightly more challenging drive.

Both routes involve navigating challenging terrain, including rocky sections and unpredictable river crossings that can fluctuate based on recent weather. There are tougher trails from the north, but the F235 is the most popular and direct option for most people. The F235 starts at the F208 intersection and stretches for 23 kilometers (14 miles). 

Along this route, you'll experience sandy tracks surrounded by a vibrant green and black desert of moss and volcanic ash. While you'll encounter several small river fords along the way, none of them pose significant challenges compared to other routes.

Driving through the Highlands of Iceland

Getting There From the South

For those starting from the south, the journey begins from Road 1 (Ring Road). It takes just under an hour to cover the 50 kilometers (31 miles) to Eldgjá. The initial 16 kilometers (10 miles) on the dirt road after turning onto the F208 are relatively smooth, but the adventure truly begins after. The road then shifts into a bumpy 24-kilometer (15-mile) off-road track, with only one significant river crossing before reaching the F235.

Getting There From the North via Landmannalaugar

Coming from Landmannalaugar, the distance to the F235 intersection is about 30 kilometers (19 miles). This route is undeniably scenic but includes multiple river crossings, which will slow your progress. Expect the drive to take around an hour, given the number of fords to navigate.

Best Time to Visit

The best time to visit Langisjór lake is during summer in Iceland, from late June to early September. This is when the F-roads, including F208 and F235, are accessible, and driving conditions are at their safest.

During this period, the snow has melted, and the rivers are more manageable for crossings, making the journey to Langisjór much smoother. Attempting to visit outside of this window is risky, as the roads are often closed due to harsh weather conditions.
