Travel Guide Reserva Natural Volcán Cosigüina

The most violent eruption in Nicaragua's recent history was that of the Cosigüina volcano on 22 January 1835. A large portion of the crater exploded and large pieces of rock landed in the neighbouring Gulf forming Fonseca Islands. Ash rains were driven by winds to Mexico City, 1400 kilometres away. Indeed, these same ash clouds blocked sunlight over a radius of 150 kilometres around the volcano. After this very brutal eruption, other small eruptions took place, and then the volcano finally fell asleep in 1859. A lake then developed at the trough of this large crater 2 kilometres in diameter. From the top of 873 metres of the volcano, a magnificent panorama offers visitors: the crater, its lake, the dry tropical forest… In the background, beyond the Gulf of Fonseca, the two neighbouring countries, El Salvador and Honduras, are clear.
