From Reykjahlíð, it is possible to go to many sights in the area, most notably Krafla. The volcano last erupted in 1984, but the vapour of a warm lava field and of sulphur springs can still be seen. Not far from there is the crater Víti (meaning hell in Icelandic), but looking today rather harmless with a blue lake at its bottom. Its apparent tranquility belies the fact that its last eruption was as recent as 1976.
