A canyon that already seems like a story
Ásbyrgi does not appear as a simple gorge, but as a horseshoe-shaped basin opening in northern Iceland with an almost theatrical form: about 3.5 km long, just over 1 km wide, with inner walls rising to 100 metres and, at its centre, Eyjan, the isolated ridge that breaks the symmetry of the place. Its geometry is so distinct that it seems almost made for a narrative explanation. (vatnajokulsthjodgardur.is)
For this very reason, Ásbyrgi has become one of the Icelandic landscapes most readily read through myth: the place seems to pose a question, and tradition has answered it with a memorable image. Even before it is spoken of as a natural attraction, it is understood as a storied form. (vatnajokulsthjodgardur.is)
The legend of Sleipnir’s hoofprint
The best-known version says that Sleipnir, Óðinn’s eight-legged horse, set one hoof upon the ground here and left in the earth the mark that we now recognise in the hollow of the canyon. The legend works because it turns an unusual landform into a divine gesture: it does not merely explain the outline, but invests it with presence. (vatnajokulsthjodgardur.is)
Sleipnir, moreover, is no ordinary creature of Norse mythology. In Snorri Sturluson’s Gylfaginning, he is presented as the finest of the gods’ horses, owned by Óðinn and endowed with eight legs; later, Snorri also shows him as the horse chosen for Hermóðr’s ride towards Hel. The horse evoked by Ásbyrgi thus belongs to a clearly defined medieval world of imagination, not to an indistinct body of folklore. (sacred-texts.com)
From mythology to local tale
Here it is worth keeping the different levels distinct. The medieval text preserves Sleipnir within Norse mythology, but does not connect Ásbyrgi with the horse; the link between canyon and hoof, by contrast, belongs to a later explanatory tradition, now repeated by the park authorities as a local legend. It is therefore not a saga scene set in Ásbyrgi, but a folkloric reading of the landscape built around a figure already well known. (vatnajokulsthjodgardur.is)
This distinction matters for the contemporary reader as well: the story of Sleipnir does not arise from the canyon, but the canyon has adopted Sleipnir as a key to its interpretation. This reverses the relationship found in many simplified tourist guides, where the myth seems to precede the place; here, instead, the place is real, and the legend clings to it like a second narrative skin.

Geology, name, and resemblance
Geology tells another story, very concrete and no less impressive. The park explains that Ásbyrgi was formed in at least two great jökulhlaup from Vatnajökull: one between 8,000 and 10,000 years ago, and another around 3,000 years ago. Since then, the Jökulsá has shifted eastwards, leaving the basin high and dry. The legend does not replace this origin; it accompanies it, because the canyon’s very shape invites it to be read as a hoofprint. (vatnajokulsthjodgardur.is)
The name, too, helps explain why the tale found such fertile ground. Ásbyrgi may be interpreted as composed of áss, “god”, and byrgi, “enclosure” or “shelter”: a place name that sounds like “shelter of the gods”. This etymological reading does not prove the legend, but it explains its naturalness: a place so named seems almost to ask for a divine story. (heimskringla.no)
The second layer: álfa and huldufólk
Alongside Sleipnir there is a second layer of associations, different and more fluid. In the park’s presentation, especially around Botnstjörn, it is said that many people sense a particular sacredness in the site and imagine it as the dwelling place of álfa and huldufólk. This is a parallel tradition, not the same story as that of Óðinn’s horse: rather than explaining the canyon’s shape, it intensifies its narrative aura. (vatnajokulsthjodgardur.is)
For this reason, Ásbyrgi should be read as a layered landscape. On one side lies the basin carved by floodwaters; on another, the legend of the great divine horse; between them, the local and modern sensibility that continues to attribute a further presence to the place. Those who arrive today encounter not only a hollow among basalt and vegetation, but a site where nature, name, and story have learned to coincide without becoming the same thing.
