Volcán Cerro Machín

Cerro Machín is a stratovolcano on the eastern flank of the Central Cordillera that rises to 2,650 meters and holds a crater measuring 2.4 kilometers across. Inside this crater sit three dacite domes that shape the volcanic landscape.

Scientists have recorded six major explosive eruptions over the past 5,000 years, with the most recent taking place roughly 900 years ago. These eruptions left ash deposits now scattered across much of the surrounding region.

The volcano area holds agricultural significance for local communities who maintain farms and livestock operations on its fertile slopes.

Access requires a 4x4 vehicle to handle the unpaved road from Ibagué that climbs steeply through narrow mountain paths. The drive can take several hours depending on weather, so plan to leave early in the morning.

An active hydrothermal system generates fumaroles and thermal springs across the volcano, while ongoing microseismic activity signals underground magma movement. Measurements have also detected elevated radon concentrations around the crater area.
