The Active Costa Rica Volcanoes
1. Arenal Volcano
Arguably the most famous, Arenal was Costa Rica’s most active volcano until 2010. Though it’s currently in a resting phase, it still draws visitors for its symmetrical cone, lava fields, and nearby hot springs in La Fortuna.
2. Poás Volcano
Located in the Central Highlands, Poás features one of the largest craters in the world. It’s known for its acidic, turquoise-blue lagoon and occasional steam eruptions. The national park is easily accessible and has re-opened after periods of volcanic activity.
3. Irazú Volcano
The highest volcano in Costa Rica, Irazú is famous for its eerie, moon-like landscape and emerald crater lake. Located near Cartago, it has erupted several times in recorded history, including a major event in 1963.
4. Turrialba Volcano
Often paired with Irazú, Turrialba has become more active in recent years, with ash eruptions affecting San José and beyond. Access is sometimes restricted due to activity, but the surrounding region offers great hiking and nature experiences.
