The Arenal Volcano is the only volcano in Costa Rica constantly active since it woke up after 400 years with the big 1968 eruption producing huge ash columns, explosions & glowing red lava almost every day.

The Arenal Volcano National Park is located in the Northern Region of the country, in the Tilaran Mountain Range. It belongs to Tilaran, San Carlos and San Ramon. This park protects important plant and animal species, commonly found in the rain and cloud forests, each with a high tourist and scientific value. The impressive and majestic Arenal Volcano features an almost-perfect cone at a height of 1,633 meters, whose regular eruptions offer one of the most extraordinary and imposing natural occurrences in Costa Rica. The Arenal is an active volcano which has been generating constant lava flows for the last 30 years. These lava flows with their incandescent rocks, its ash and rock throwing explosions and the sounds produced by the de-gasification of the volcano constitute part of its normal activity during the active period.
