We visited the Montañas del Fuego (Fire Mountains) which were created between 1730 and 1736 when more than 100 volcanoes, covering more than 50 km², rose up and devastated this part of the island (including several villages). The last eruptions were in 1824, however due to the low rainfall (and therefore lack of erosion) this area appears much the same as it did just after the eruptions. In 1968 the area was declared a national park, Parque Nacional de Timanfaya.
