Sumaco

Sumaco is a stratovolcano in Napo Province that rises to 3,990 meters and features a wide crater at its summit. Dense cloud forest covers the slopes, creating a wet and green environment that changes dramatically with altitude.

Sumaco last erupted around 1895, representing the final period of volcanic activity documented in this area. Since then, the mountain has remained geologically quiet.

Indigenous communities near Sumaco maintain traditional practices that incorporate the mountain into their understanding of natural elements and territory.

Climbing this peak requires experienced local guides and proper equipment, as weather changes rapidly and visibility is often limited. An early start and planning around the best climbing season are essential for safety.

The mountain is home to a rare frog species called Pristimantis ernesti, found nowhere else except at the summit. This tiny amphibian thrives in the misty conditions at the very top of this isolated peak.
