Lake Habema sits high above the Baliem Valley, around 3,200 metres up in Papua's mountain country. The landscape is a sharp change from the valley floor: cold air, moorland, mossy forest, orchids, and views toward the higher peaks when cloud lifts.
Reaching it usually means a long drive from Wamena and either a guided excursion or the start of a longer trek. The lake is worth considering if you want to see the Baliem region as more than villages and valley paths, but the altitude and weather make it a proper mountain outing.
