A small Dani settlement on the eastern side of the valley, an hour or so from Wamena by bemo, and a common base for short treks. Jiwika is the easiest place to see traditional honai-cluster compounds, watch the smoke from morning fires drifting through thatched roofs, and visit the nearby villages where Dani mummies are kept.
A simple losmen (the Lauk Inn was the historic standby) gives you a base for hikes to the salt wells at Iluwe, the caves at Gua Kontilola and Gua Wikuda, and the ridgetop villages above the road. Expect to negotiate small fees for photos and for entry to mummy-keeping compounds.
