A good day trip from Angoram is to travel south on the Keram River to Kambot, stopping at Chimondo (often spelt Sumundo) on the way; Wavi Guesthouse can help arrange a boat. While there's little to see in Chimondo besides the skeletal remains of a haus tambaran, Kambot is the home of the Sepik story boards. The river is narrow and winding, and the banks are crowded with luxuriant growth that attracts many ibises.
It’s possible to stay in a simple guesthouse at Kambot (ask for David Bamdak). A traveller reported that he was allowed to pitch his tent on the platform in the Kambot haus tambaran and spent a magical night camped under its carved struts. It’s doubtful that this invitation would be extended to women.
