About Lake Lagarfljót
Lake Lagarfljót is a remarkable natural wonder in East Iceland. This breathtaking natural attraction showcases the diverse and dramatic landscapes that make Iceland one of the world's most unique destinations. From its geological formations to its rich biodiversity, this site offers an unforgettable experience.
History & Background
The monster legend of Lagarfljót dates to 1345, when a girl allegedly placed a small worm on a gold ring to make it multiply. Instead the worm grew to enormous size and was thrown into the lake, where it has been terrorizing locals ever since. Sightings have been reported for nearly 700 years and a 2012 video claiming to show the creature under ice went viral worldwide. The lake is murky with glacial silt from Vatnajökull, which may explain why the legend has persisted so long — nobody can see what's in the depths.

Book NowStory & Folklore
Lagarfljót is Iceland's third largest lake and the one with the best monster story. According to Icelandic folklore, the Lagarfljótsormurinn — a giant serpent-like creature — was first sighted in 1345 and has been reported in the lake ever since. The most famous sighting was a 2012 video apparently showing a large creature undulating under the surface, which went viral and was officially declared genuine by a national commission (though scientists remain sceptical). The lake itself is 53 km long, 10 km wide and 112 metres deep. It is fed by meltwater from Vatnajökull and its unusual grey-green colour comes from glacial silt. The surrounding birch forest, Hallormsstaðaskógur, is Iceland's largest.
