Lagarfljót Lake
About Lagarfljót Lake
Lagarfljót is Iceland's third largest lake by surface area and its longest, stretching approximately 53 km through a broad valley in East Iceland. Fed by glacial meltwater from Vatnajökull, the lake has characteristic murky blue-gray coloring caused by glacial sediment suspended in the water. The lake is surrounded by some of East Iceland's most beautiful scenery, including the forested slopes of Hallormsstaðaskógur on its eastern shore and mountains rising to the west. A scenic road follows much of the western shore, offering excellent views across the water. Beyond its natural beauty, Lagarfljót is famous in Icelandic folklore as the home of the Lagarfljótsormurinn — a serpent-like creature recorded in historical texts dating back to the 14th century. Alleged sightings continue to this day, making it a fascinating stop for those interested in Iceland's mythology and legends.
🐉 The Elves of the Eastern Fjords
The steep mountains and narrow fjords of East Iceland are considered one of the most enchanted regions of the country. Local tradition holds that entire communities of elves (álfar) live inside the mountains, with their own towns, churches, and social structures mirroring human society. Fishermen in eastern fjord villages have long reported seeing lights in the mountainsides on dark winter nights — the windows of elf houses, they say. Some families maintain that their ancestors had regular contact with the elf-folk, trading goods and sharing knowledge. The belief is so persistent that construction projects in the region still sometimes account for known elf dwellings.
