Jayawijaya Mountains, Mountain range in West Papua, Indonesia.
The Jayawijaya Mountains run through New Guinea's central highlands and connect several major mountain ranges together. The region contains multiple valleys where communities farm and live, creating pockets of settlement across the terrain.
An exploration flight in 1938 discovered the Baliem Valley and revealed an isolated population with its own farming system. This finding showed how little the outside world knew about these mountains at that time.
The Dani people farm the valleys here using methods passed down through many generations. You can see their traditional wooden houses with thatched roofs scattered across the landscape, and locals gather regularly at markets to trade and socialize.
Access requires special permits and a local guide because the region is remote and difficult to reach. The drier season offers better conditions for travel, and visitors should expect physically demanding terrain.
Several peaks exceed 4,500 meters and can periodically hold snow, which is unusual in Indonesia's tropical region. This elevation creates a special environment with different climate zones found within a short distance of each other.
