The Cordillera de Guanacaste is a mountain range in northern Costa Rica close to the Nicaraguan border. The range includes a considerable number of active and dormant stratovolcanoes. The most famous one is also one of the highest volcanoes of the range: the Arenal volcano. It last erupted in 1968, destroying two villages and covered the entire region with volcanic ash. Arenal is still active today, even though the danger of another fatal eruption is not considered very high in the foreseeable future.
