Þríhyrningur, Mountain summit in Southern Iceland
Þríhyrningur is a mountain summit with three distinct peaks rising 678 meters above the surrounding terrain in Southern Iceland. From its heights, you can see both the Eyjafjallajökull glacier and Hekla volcano across the landscape.
This peak formed during glacial periods and is composed of tuff stone, indicating an age exceeding 12,000 years. The mountain's ancient geology reveals how ice and volcanic activity shaped Iceland's landscape across millennia.
The mountain appears in Njálssaga, the famous Icelandic saga, where it served as a refuge before a major attack. Visitors walking through this landscape feel connected to stories that have shaped Iceland's cultural identity for generations.
The hiking trail begins at a parking area near the Fiská river, accessible via Fljótshlíðarvegur road from Hvolsvöllur. Starting early and bringing weather-resistant gear helps ensure a safe and comfortable climb regardless of changing conditions.
The mountain sits within Katla Geopark and its three peaks form a distinctive shape visible from across the Fljótshlíð region. This recognizable formation serves as a natural landmark for navigation and helps travelers understand the surrounding terrain.
