Umsini Mountain
Umsini Mountain (Gunung Umsini) rises in the cloud-draped interior of the Arfak Mountains, the range that forms the spine of West Papua's Bird's Head Peninsula. It is cited in official and regional accounts as the highest point in West Papua, and the name carries an appealing mystery: depending on the map, "Umsini" has been attached to summits anywhere from roughly 2,735 to 2,950 metres, with experienced trekkers noting the label drifts across peaks the way the mist does across the ridges. What is consistent is the setting — a steep, rain-soaked, roadless wilderness of mossy forest and village foot-trails inside the Arfak Mountains Nature Reserve, far from the crowded trails of Indonesia's volcanic islands. This is not a casual viewpoint stop but a genuine expedition for walkers who want raw adventure and some of the most spectacular birdlife on Earth. You come here to climb cool, misty slopes above the tree line of lowland jungle, to spot birds of paradise and the Vogelkop Bowerbird that made these forests world-famous, and to glimpse the twin highland lakes of Anggi from the surrounding ridgelines — with local Arfak guides as your essential partners in a terrain that is famously hard to read.
