Þríhyrningur

The three distinct peaks of Þríhyrningur rise to an elevation of 678 meters, offering views of Eyjafjallajökull glacier and Hekla volcano.

Geological studies indicate that Þríhyrningur formed during glacial periods, with tuff stone composition suggesting an age exceeding 12,000 years.

The mountain plays a central role in Njálssaga, where Flosi Þórðarson and his men used it as a hiding place before their attack.

The hiking trail to Þríhyrningur starts at the parking area near Fiská river, accessed via Fljótshlíðarvegur road from Hvolsvöllur through Tumastaðir.

The mountain stands within Katla Geopark, where three summits create a geographical formation visible from the surrounding Fljótshlíð region.
