What is Thrihyrningur?
Thrihyrningur is a three-peaked mountain in the Fljotshlid area of South Iceland. Its name reflects that shape, and the mountain is strongly tied to the inland landscapes behind the busy waterfall belt.
The area has saga associations and views toward some of South Iceland's major landmarks, including Eyjafjoll, Hekla country and the Markarfljot lowlands.
Why visit Thrihyrningur?
Visit Thrihyrningur if you want South Iceland hiking without making the day only about the Ring Road. It is a better fit for travellers staying around Hvolsvollur, Hella or the Fljotshlid area than for rushed day-trippers.
It also works as a bridge between cultural South Iceland and nature touring: saga landscapes, farms, mountain views and access routes toward Thorsmork all sit close together.
How to visit Thrihyrningur
Choose the route carefully and check conditions. The mountain is exposed, and the best experience depends on visibility.
For many travellers, a guided local 4x4 route or highland day may be more useful than trying to turn Thrihyrningur into a quick unsupervised hike.
