Baliem Valley Festival in Wamena
Baliem Valley Festival, held each August since 1989 in the foothills near Wamena, reenacts staged mock inter-tribal battles among the Dani, Lani, and Yali highland peoples, historically used to affirm strength after harvest. The three-day event features traditional dress, pig feasts, and pikon mouth-harp performances, with one recent edition drawing fifteen hundred players in a single mass performance.
Wamena's surrounding foothills in the Walesi District have hosted the Baliem Valley Festival since 1989, when it began as an effort to preserve the ritual inter-tribal warfare once used by the Dani, Lani, and Yali highland peoples to affirm strength and prosperity following the harvest.
