Story & Folklore
Leirhnjúkur is the most accessible lava field from the Krafla Fires (1975–1984) — a still-steaming expanse of black lava, sulphur deposits and fumaroles on the floor of the Krafla caldera, where only 40 years ago rivers of molten rock flowed. Marked walking trails guide visitors through the cooled-but-still-hot terrain (temperatures a metre below the surface still approach boiling). The contrast between the steaming vents and the absolute stillness of the surrounding landscape is extraordinary. Snow on the surrounding hills often melts in patches above the geothermal spots. On the longest day, the midnight sun catches the fumarole steam in golden light — a sight of unusual beauty in an unusual landscape.
