Stuðlagil canyon, Basalt canyon formation in Múlaþing, Iceland.
Stuðlagil Canyon features towering hexagonal basalt columns formed by ancient volcanic activity, creating dramatic vertical walls along the flowing glacial river that winds through the deep gorge.
The canyon remained hidden beneath river waters until 2009 when the construction of the Kárahnjúkar Hydropower Plant reduced water levels, exposing the spectacular basalt formations for the first time.
Local Icelandic folklore describes the basalt columns as remnants of ancient giants or meeting places for mythical elves, reflecting traditional beliefs about supernatural beings inhabiting natural landmarks.
Visitors can access the canyon via a 2.5-mile hiking trail from Klaustursel Farm parking area, with the eastern viewpoint offering the best panoramic views of the formations.
The Jökla River displays seasonal color variations, appearing bright turquoise from March to July due to glacial meltwater, then shifting to grayish tones later in summer.
