Park
Parque Nacional Volcán Arenal
From 1968 until 2010, Volcán Arenal was an ever-active and awe-striking natural wonder, producing menacing ash columns, massive explosions and streams of glowing molten rock almost daily. While the fiery night views are gone for now, this mighty mountain is still a worthy destination. Part of the Area de Conservación Arenal, the park is rugged and varied, with about 15km of well-marked trails that follow old lava flows. Hikers routinely spot sloths, coatis, howler monkeys, white-faced capuchins and even anteaters.
