Wa! Wa! Wa!
it means greetings and thank you in Baliem Valley.

Baliem Valley of Irian Jaya, is Indonesia's most remote province is a valley in mountainous Jayawijaya, capital town of the Jayawijaya Regency of Indonesia. It is the largest town in Indonesian Papua's highlands, situated at an altitude of 1,600 meters above sea level in the heart of the Cyclops Mountains surrounded by unspoiled and beautiful scenery. Temperatures can reach 10-15 degrees Celsius at night. Wamena is the only town in the valley though it is estimated that 250,000 Dani live in the region.

There are three mains tribes inhabiting the Baliem Valley (Wamena). The Dani in the main valley, the Lani to the west and the Yali in the south-east. Each tribe has a distinct culture. One interesting way to distinguish between the tribes is from the Koteka. The men of each tribe tend to the growing of the gourds with the three tribes each cultivating a different style. The Dani use a long, thin Koteka, the Lani sport a medium sized, wide cannon-like gourd, and the Yali wear the longest of all.
