Gjástykki Travel Guide
Gjastykki is a beautiful and rugged rift valley to the north of the caldera Krafla, in the North of Iceland.
Gjastykki was literally blown apart by the eruption of Krafla during the years 1975-1984. Two of the three areas that were active during that time are still warm.
The area is covered with multicoloured slag from the Krafla eruption and bears stark witness to the movement of the tectonic plates.
