Fissures and Formations

Mývatn, Iceland

Mývatn, Iceland

A journey through an area of extreme contrasts and geology. 

We hike through the typical green “woods” of Iceland, exploring fissures and caves along the way. 

On the way, we visit the Grjotagja caves made famous in the series “Game of Thrones” 
and then hike up to the top of the biggest tephra crater in Europe “Hverfjall” crater (130m) and descend on the steeper southern side. 

The route then continues to the “dark castles” Dimmuborgir lava park where we explore lava formations and learn about the trolls that live there and in the mountains in the area.

Duration: 3-4 hours.
*Guidance and transfer back from Dimmuborgir included!
