One of the major attractions of the Krafla area is Leirhnjúkur hill and its solfataras.
Leirhnjúkur hill split open in January 11, 1725, spouting lava. After a minor burp in 1746, it became the manacing sulphur-encrusted mud hole.
The earth's crust here is extremely thin and in places the ground is ferociously hot. Steaming vents on the pastel-coloured rhyolite mountain to the west are the last vestiges of a series of explosions in 1975.
