Wosilimo (‘Wosi’) is a relatively major village with a couple of kiosks. The cave here, Gua Wikuda, is said to be several kilometres long, with an underground river that reaches Danau Anegerak. It’s possible to visit about the first 100m of the cave, which has a few stalagmites and 'tites. Ask for the lights to be turned on. There are some small guest honai near the cave entrance, which have straw floors, sleeping mats and a filthy shared mandi with squat toilet. Bring food and the people there will cook for you. It’s handy during the Baliem Valley Festival but is otherwise avoidable.
Two kilometres south from Wosi, along the main road, a path starting in front of a church leads half an hour southwest to a small lake, Danau Anegerak, crossing a hanging bridge over Kali Baliem on the way. It’s a pleasant walk, though during wet weather it may be impassable.
