Parque Nacional Volcán Arenal

For most of modern history, Volcán Arenal was just another dormant volcano surrounded by fertile farmland. But for about 42 years – from its destructive explosion in 1968 until its sudden subsiding in 2010 – the volcano was an ever-active and awe-striking natural wonder, producing menacing ash columns, massive explosions and streams of glowing molten rock almost daily.
