Lastarria

Lastarria is a stratovolcano in the Andes mountain range with a symmetrical cone shape rising to about 5,700 meters. Its structure is built from basaltic and andesitic lava layers typical of volcanic mountain formations.

The volcano formed during the Pleistocene epoch roughly 800,000 years ago. Since then, the landscape has slowly evolved as periodic volcanic activity reshaped its form.

Local Andean communities have long regarded these mountain peaks as sacred places where spiritual forces dwell. People still visit such mountains for ceremonies and to feel connected to the land around them.

The remote location requires specialized equipment and experienced guides, as the nearest settlements are more than 150 kilometers away. Visitors should prepare for a challenging hike at high altitude in harsh climate conditions.

Its surface features an active hydrothermal system with fumaroles reaching temperatures around 408 degrees Celsius. These hot steam vents create small cones and openings that distinctly mark the terrain.
