A massive horseshoe-shaped canyon created by Odin's eight-legged horse. A key stop on the Diamond Circle and part of Vatnajökull National Park.
Story & Legend
According to Norse mythology, this massive horseshoe-shaped canyon was created when Odin's eight-legged horse, Sleipnir, touched one of his hooves to the earth. It is considered the capital of the 'Hidden People' (Elves) in Iceland. The acoustics against the sheer cliffs are so perfect that it feels like a natural amphitheater.
Geology & Science
Scientifically, this wonder was carved by catastrophic glacial flooding (Jökulhlaups) from the Vatnajökull glacier thousands of years ago. The walls are up to 100 meters high. In the center stands 'Eyjan' (The Island), a distinctive rock formation left standing while the river washed everything else away. This area is the northernmost territory of the vast Vatnajökull National Park, protecting its unique birch forests and geological formations.
Safety
This is one of the safest hiking areas in Iceland, with well-marked trails through a rare birch forest. However, if you climb the cliff rim, stay well back from the edge as loose rocks are common. The area is a sanctuary, so drones are often restricted during nesting season.
Photo Tip
Walk to the very end of the canyon to find Botnstjörn pond. On a calm day, the reflection of the vertical cliffs in the water is mirror-perfect. The best light is mid-day to ensure the sun reaches the canyon floor, or golden hour for the red hues on the cliffs.
Insider Tip
Skip the basic viewpoint and hike the Eyjan (The Island) trail right in the middle of the canyon. It gives you a spectacular 360-degree view of the towering 100-meter vertical cliffs surrounding you.
Best Time to Visit
Late summer or early autumn when the dense birch forest inside the canyon turns bright yellow and orange, offering a stark contrast to the grey cliffs.
What to Bring
Good hiking shoes. The trails range from flat paved walkways near the pond to rocky, uneven climbs if you scale the canyon walls.
