Volcan Arenal and the landscape shaped by fire

Volcan Arenal rises above La Fortuna as a steep volcanic cone surrounded by rainforest, lava fields and the waters of Lake Arenal. Its visible form belongs to a landscape reshaped by eruptions, especially the major eruption that began in 1968.
Volcan Arenal: a young cone above La Fortuna
Volcan Arenal lies in northern Costa Rica, near La Fortuna, within the Arenal Volcano National Park. The mountain reaches about 1,670 m (5,479 ft), although published measurements also give 1,633 m (5,358 ft). The difference reflects varying reference points and measurements.
Arenal is a stratovolcano, a steep volcanic mountain formed from successive layers of lava, ash and other eruptive material. Its cone rises above the eastern shores of Lake Arenal, linking the mountain visually with forested slopes and open water. The volcanic massif belongs to the volcanic landscapes of Costa Rica’s northern interior.
1968 and the landscape of lava
Volcan Arenal’s modern history is associated with the eruption that began on 29 July 1968. Hot ash covered pasture, villages were destroyed, and the surrounding landscape received lava and other volcanic debris. The eruption created a lasting historical association between the mountain and the communities around La Fortuna.
Activity continued through the following decades, with lava flows, explosions and ash emissions recorded from the summit and upper western flank. This eruptive period ended in December 2010. The mountain remains classified as an active volcano, but its visible landscape is defined by the contrast between a dark volcanic cone, green vegetation and the broad surface of Lake Arenal.
Rainforest, old lava and protected land
The Arenal Volcano National Park protects volcanic terrain and rainforest around the mountain. Trails cross forest and areas affected by historic lava flows, including deposits associated with the eruption of 1992. The landscape also contains large trees, wildlife habitat and volcanic rock.
The park was created in 1991 and expanded through legal measures in the 1990s. Its setting connects Volcan Arenal with the wider Arenal conservation area, where forest, waterways and volcanic landforms occupy the same regional landscape. Arenal Volcano National Park provides the protected setting around the cone.
The mountain’s volcanic identity is also recorded in its geological history. The earliest known eruptions date from about 7,000 years ago, while the 1968 eruption opened the modern period of sustained activity. The Smithsonian volcano record lists a last known eruption in 2010 and an elevation of 1,670 m.
