After lying dormant for centuries, Mt. Arenal erupted in 1968 and continued its explosions until 2010. It has now entered a period of quiescence and the customary activity has subsided.

Once one of the most active of the 60+ volcanoes in Costa Rica, this composite cone shaped volcano rises 1,657 metres, an impressive and iconic sight.

The surrounding national park contains fascinating landscapes of solidified lava flows, as well as lush rainforest, is home to howler monkeys, toucans and a wealth of other bird species.

Nearby highlights include thermal baths at Tabacón, wetlands of Caño Negro Wildlife Refuge, and white-water rafting on the area’s numerous rivers.
