Few mountains in the world have a shape as recognizable as Arenal Volcano. Its almost symmetrical cone rises above the plains of San Carlos, in the province of Alajuela, and on clear days it looks as if it had been drawn by hand. It is, without exaggeration, one of the most famous postcards of Costa Rica.
A giant that woke up suddenly
For centuries Arenal looked like just another forest-covered mountain. Everything changed on July 29, 1968, when a sudden eruption buried the villages of Tabacón and Pueblo Nuevo. From then until around 2010, the volcano stayed in almost constant activity: lava flows, ash columns and, at night, glowing rocks rolling down its slopes.
Today Arenal is in a resting phase, but it is still an active, monitored volcano. That history explains the landscape around the park: old lava fields now covered by young vegetation, showing how nature slowly takes the land back.
The landscape around it
- Lake Arenal: the largest reservoir in the country, with spectacular sunset views of the volcano.
- Hot springs: volcanic heat warms rivers and pools around La Fortuna.
- Trails over old lava: Arenal Volcano National Park has paths through secondary forest and viewpoints.
- La Fortuna Waterfall: just a few kilometers away, a waterfall about 70 meters high.

Tips for your visit
- Go early: the summit is often covered by clouds after midday.
- Bring a rain jacket or umbrella; it rains often in the area all year round.
- Climbing to the crater is not allowed: stay on the marked trails.
- Check opening hours and fees on the official SINAC website before you go.
Arenal is a reminder that Costa Rica’s landscape is not still: it was shaped, and is still being shaped, by fire and water.
