Sierra Velluda

Sierra Velluda is a stratovolcano in the Bío Bío Region that dominates the landscape of Laguna del Laja National Park with its two distinct summits. This mountain reaches 3,585 meters in elevation and stands as the park's highest peak.

The volcano formed in two distinct phases, with the initial stage occurring roughly 500,000 years ago and producing extensive lava flows and rocky debris. This early activity established the mountain's fundamental structure.

The mountain serves as a central reference point for local communities and represents a significant landmark within the Chilean Andes range.

Those planning to climb this mountain begin at Los Barros and will need specialized climbing equipment for the route. The ascent typically takes three days and demands proper physical preparation.

Glacial erosion has revealed the ancient volcanic layers, exposing geological structures spanning nearly half a million years. These visible rock formations tell the story of repeated volcanic activity across vast timescales.
