The Lagarfljót Worm is a legendary lake monster said to inhabit Lagarfljót, a lake in eastern Iceland. Reports of this mysterious creature, often described as a giant serpent or dragon, have appeared in Icelandic folklore for centuries, with the earliest written account dating back to 1345.
Locals and visitors alike have claimed to spot the creature’s humps rising above the water, sparking comparisons to other famous lake monsters around the world. The Lagarfljót Worm remains one of Iceland’s most enduring legends, fueling curiosity and debate about what, if anything, lurks beneath the lake’s surface.
Origins of the Lagarfljót Worm Legend
The Lagarfljót Worm’s story weaves together centuries-old myth, recorded history, and Icelandic cultural beliefs. Reports span from medieval chronicles to local folklore, highlighting how this serpent became a persistent figure in Iceland’s collective imagination.
Icelandic Folktales and Early Accounts
The Lagarfljót Worm legend forms part of Icelandic folktales that often feature extraordinary creatures. In these tales, the worm is described as a massive serpent or dragon living in Lagarfljót lake near Egilsstaðir.
Folklore claims the creature came from a small “heath-worm” placed on a gold ring, which then grew after being thrown into the lake. Stories of its colossal size, ability to cause natural disasters, and interactions with people have circulated for generations.
Such narratives were not unusual in Iceland, where the natural environment inspired stories of hidden beings. The Lagarfljót Worm legend reflects a blend of reality, superstition, and the ever-present mystery surrounding isolated Icelandic landscapes.
1345: The First Recorded Sighting
The first written account of the Lagarfljót Worm dates to 1345, as recorded in the Icelandic Annals. This document mentions a sighting of a large serpent in Lagarfljót, marking the earliest known reference to the creature in historical records.
In medieval Iceland, chroniclers documented unusual phenomena alongside natural disasters and important events. Including the worm in these records demonstrates that the story held significance in the community.
The persistence of this entry helped transform a piece of local folklore into a prominent legend. It established a foundation for future sightings, making the Lagarfljót Worm one of the oldest lake monster myths in Europe.
Connection to Elves and Supernatural Beliefs
The tale of the Lagarfljót Worm is closely associated with supernatural beliefs common in Iceland. Many Icelanders, historically and even today, accept stories involving elves (huldufólk), trolls, and spirits as part of their cultural heritage.
Some versions of the legend suggest the worm’s powers or origins are linked to the elf world. There are claims that only those “with second sight” or spiritual sensitivity can see the creature. The lake itself is sometimes regarded as enchanted or protected by supernatural guardians.
These beliefs connect the worm to a wider tapestry of Icelandic myth, reinforcing the notion that landscapes are inhabited by more than just visible wildlife. For many, the Lagarfljót Worm exists at the intersection of tradition, nature, and the unseen supernatural world.
Description of the Lagarfljót Worm
The Lagarfljót Worm is a legendary lake monster said to inhabit Lagarfljót in eastern Iceland. Known for its gigantic size and serpentine form, the creature has been part of Icelandic folklore for centuries and is often compared to other mythical lake serpents.
Physical Characteristics and Depictions
Descriptions of the Lagarfljót Worm vary, but it is most often depicted as a long, snake-like creature, sometimes called a serpent or wyrm. Local tales describe it as having a length that can stretch from dozens to possibly hundreds of feet. Its body is usually said to be thick and undulating, resembling a mysterious snake or aquatic serpent.
Some reports describe the creature’s movement as rolling or looping along the surface of the lake. Sightings often mention humps rising above the water, similar to reported lake monster sightings elsewhere. Rare artistic renderings show a reptilian head, but most accounts focus on its elongated, worm-like shape without visible limbs.

Names and Variants: lagarfljótsormur, lagarfljótsormurinn, Iceland Worm Monster
The creature is known by several names in Icelandic and English. The most traditional is Lagarfljótsormur (“Worm of Lagarfljót”), with “ormur” meaning serpent or worm in Old Norse. The name Lagarfljótsormurinn adds the definite article, translating to “the Lagarfljót Worm.”
In English-language accounts, it is sometimes referred to as the Iceland Worm Monster or the Lagarfljót Worm. These names emphasize the beast’s status as a lake monster and link it to other cryptids described as “worm monsters” or “sea serpents.” Locally, it is often simply called the monster of Lake Lagarfljót.
Other terms, such as lake monster, mysterious snake, or serpent, are used interchangeably, though they may not capture the unique significance of lagarfljótsormur in Icelandic tradition. The diversity in names reflects variations in pronunciation, spelling, and the way folklore has traveled beyond Iceland.
Lagarfljót Lake: The Setting
Lagarfljót Lake is a striking glacial waterbody in East Iceland known for its unusual environment. The lake’s geography, glacial origins, and ties to local rivers and towns all contribute to its unique character.
Geography and Features of Lagarfljót
Lagarfljót Lake stretches about 25 kilometers in length and covers an area of roughly 53 square kilometers. At its deepest point, the lake reaches 112 meters. Its long, narrow shape is framed by valleys and low mountains.
The lake is accessible by roads and bridges at both ends, making a complete drive around it possible. This accessibility supports both tourism and local life. The surrounding landscape features forests and farmlands, most notably the Hallormsstaðaskógur forest, one of Iceland's largest woodlands.
Lagarfljót is notable for its cold, opaque waters, often tinged by glacial silt. Some sections freeze during winter, but the overall water movement ensures that it does not freeze completely very often.
Siltation and Glacial Influences
Lagarfljót is a glacial lake, fed largely by meltwater from surrounding glaciers. Glacial silt suspended in the water gives it a milky appearance and reduces visibility below the surface.
Siltation is a continuous process here. Meltwater from seasonal thaws—and sometimes from volcanic activity—carries fine sediment into the lake. This sediment not only alters the color of the water, it also impacts aquatic life.
The lake’s silt-laden composition makes it special among Icelandic lakes. It is less favorable for clear-water species but provides a distinct habitat adapted to low light and fluctuating conditions.
Relationship to jökulsá í fljótsdal
The lake is closely linked to the glacial river Jökulsá í Fljótsdal, which enters Lagarfljót from the southwest. This river is a major source of inflow, delivering both water and silt into the lake.
Jökulsá í Fljótsdal’s flow is affected by seasonal glacier melt, so the water level and characteristics of Lagarfljót can change throughout the year. At times of heavy melt, both the volume and turbidity of the lake increase.
Hydroelectric developments in the area have modified some of the natural flow, but the essential relationship between river and lake remains central to their ecology. This interconnected system shapes both the landscape and the water quality.
Nearby Town: Egilsstaðir
The town of Egilsstaðir sits near the eastern end of Lagarfljót Lake. As the largest settlement in East Iceland, Egilsstaðir functions as a regional hub for travel, trade, and community life.
The town’s proximity to the lake makes it a starting point for visitors exploring Lagarfljót and its legends. Key amenities, such as accommodations, restaurants, and cultural sites, are all centered here.
Egilsstaðir’s role extends to environmental management and conservation efforts tied to the lake and surrounding forests. The relationship between town and lake is practical, but it also carries the folklore and traditions linked to the area, including tales of the Lagarfljót Worm.
Famous Sightings and Eyewitness Accounts
Lagarfljót Lake has been the site of repeated claims of strange serpentine creatures for centuries. Accounts range from historical records in the 14th century to modern photographs and videos, with several instances drawing national attention.
Notable Events and Photographs
Notable eyewitness accounts date back to at least 1345, when early chronicles mention a large serpent-like beast in the waters of Lagarfljót. Over the years, multiple individuals have reported similar encounters, often describing a creature several meters long with an undulating, worm-like motion.
In 1861, a group of travelers claimed to see the creature's back emerging from the water. Decades later in 1967, forestry station employees at Hallormsstaður observed something large swimming up the lake and tracked it for a significant distance.
Occasionally, photographs reportedly capturing the Lagarfljót Worm have circulated. However, most images are either inconclusive or blurry, leaving the authenticity of the sightings open to debate.
Hjörtur Kjerúlf’s Video Evidence
One of the most widely publicized modern pieces of evidence comes from Hjörtur E. Kjerúlf. In 2012, Kjerúlf filmed a video on the icy surface of Lagarfljót Lake, which appears to show a long, twisting object moving beneath the water.
The video was quickly shared online and gained national and international interest. Some viewers saw it as convincing evidence that a creature inhabits the lake, while skeptics suggested it could be fishing line or ice debris moved by the current.
Since its release, the video has been analyzed by both local authorities and cryptozoology enthusiasts. It remains one of the best-known pieces of material related to the Lagarfljót Worm legend.
Role of Fishing Nets and Mysterious Creatures
Fishing in Lagarfljót Lake has long played a role in the local population’s interaction with reported mysterious creatures. Some eyewitness claims mention entangled nets and large objects striking fishing equipment under the water.
These incidents have led some to suggest that ropes, nets, or other debris could explain some sightings, especially when seen distorting or moving strangely beneath the lake surface. Others note that this does not account for all reports of serpentine shapes and movement.
The repeated involvement of fishing gear with unexplained forces has helped to reinforce the legend of a hidden creature. For many residents, these practical encounters make the phenomenon more tangible than remote stories or photographs alone.
Scientific Explanations and Skepticism
Reported sightings of the Lagarfljót Worm have encouraged debate among researchers and enthusiasts. Claims about the creature have been met with a mix of scientific analysis, skepticism, and comparison to other famous lake cryptids.
Optical Illusions and Natural Phenomena
Many experts propose that sightings of the Lagarfljót Worm are likely caused by optical illusions and natural occurrences unique to the region. The Lagarfljót lake is glacial and often opaque due to sediment-rich waters from surrounding glaciers.
This murkiness can distort objects submerged in or floating on the surface, such as logs or vegetation, making them appear serpentine when observed from a distance. Sunlight, shadows, and rippling water amplify these effects, sometimes producing shapes that closely resemble a moving creature.
Occasionally, even floating ice or debris moving in the current can give the convincing illusion of an undulating, living form. These factors contribute to a high probability of misidentification rather than unknown species.
Hoaxes and the Role of Discovery News
In 2012, a video claimed to capture the Lagarfljót Worm swimming in the river, but closer investigation revealed inconsistencies. The footage was analyzed by news outlets, including Discovery News, which identified the object as stationary, with water moving past it rather than genuine movement by a creature.
Further scrutiny showed that the so-called serpent was likely a piece of fishing net, rope, or other debris caught on ice. The movement of water, camera angles, and poor image quality helped fuel speculation but did not provide evidence of a living animal.
Hoaxes and viral videos play a significant role in spreading belief in cryptids. The tendency to share sensational footage without thorough fact-checking often results in widespread misconceptions about Icelandic lake cryptids.
Lake Cryptids: Comparing the Loch Ness Monster
The Lagarfljót Worm is frequently compared to the Loch Ness Monster, another famous lake cryptid from Scotland. Both legends involve elusive, serpent-like creatures allegedly living in large, murky lakes. Many of the claims and sightings surrounding both are similar in nature.
Eyewitness reports often describe long necks, undulating bodies, and mysterious wakes in the water. Still, scientific reviews emphasize the lack of verifiable physical evidence for both cryptids. Most reported sightings have been attributed to floating debris, animals, or optical illusions.
Like the Lagarfljót Worm, the Loch Ness Monster has been the subject of hoaxes, misinterpretations, and scientific scrutiny, keeping interest high but leaving claims unsubstantiated. These parallels underline the widespread human tendency to interpret ambiguous environmental cues as extraordinary beings.
