Surrounding the volcano are acidic hot springs, mountains of sulphur, pillars of salt, small gas geysers and pools of acid isolated by salt ridges. It makes for one of the most bizarre landscapes on planet Earth.

Haile Selassie's reign of Ethiopia, which came to an end in 1974, led to a decades long political instability which did nothing to encourage visitors. Coups, uprisings, drought and famine placed Ethiopia off the map for volcanologists and tourists alike during this period. The area in which Dallol lies was not open to foreigners until 2001 and even today an armed guard is perhaps advisable.
