Hidden in the heart of the Jayawijaya Mountains lies a monumental landmark for climbers around the world—Yellow Valley. Situated at an altitude of more than 4,300 meters above sea level, this valley is far more than a resting point. Yellow Valley is the primary gateway to one of the most iconic summits on Earth: Carstensz Peak (4,884 m), the highest mountain in Indonesia and part of the famed Seven Summits.
For those who seek extreme adventure, Yellow Valley is where ambition is tested, determination is forged, and the dream of conquering Carstensz truly begins.
An Entrance to Another World
Yellow Valley offers a landscape unlike anything else in Southeast Asia.
Massive karst formations, towering vertical cliffs, sudden descents of fog, and temperatures that can fall below freezing all combine to create a dramatic and unforgettable natural environment.
This is where climbers spend their final night before the summit push. Every step from Yellow Valley toward Carstensz feels like crossing into another world — silent, icy, and profoundly challenging.
