Arenal Volcano's Perfect Cone

Arenal Volcano is conically shaped and 1,633 metres high.

The andesitic stratovolcano sits 90 kilometres northwest of San José.

A crater 140 metres wide marks the summit.

Geologists consider Arenal young, at less than 7,500 years old.

Dormant Chato cone rests beside the main volcano.

Arenal stayed active from 1968 until 2010. Quite the run.

Magma reached the surface without major explosive events during those decades.

The volcano sits at the center of Arenal Volcano National Park.

Indigenous Maleku people consider Arenal a sacred site.

A 2022 study suggests future activity remains likely here.

Arenal has rested quietly since 2010 beneath the clouds.
