Description | Climate | Attractions | Recommendations

Irian Jaya is a land of exceptional natural grandeur. Its jungles are among the wildest, most impenetrable in the world. Eternal snow capped mountain ridges more than 5,000 meters high, with walls plunge hundreds of meters down onto floors filled with small glacier lakes. It has scenic beaches in abundance as well as immense stretches of marshlands. Cool grassy meadows lie at the foot of the towering mountains. Rivers cut through dark forests until their sluggish, crocodile infested mouths disgorge the water into the sea.

The highest peak of the central mountain range is Puncak Jayawijaya (5,500 meters). Second and third are Gunung Trikora (5,160 meters) and Gunung Yamin (5,100 meters), respectively. The biggest lake is Paniai, followed in order of declining size by the lakes Ronbenbai and Sentani, both in the vicinity of Jayapura, and Anggigita near Manokwari. On the basis of physical features and differences in language, customs, artistic expression and other aspects of culture, the indigenous people of Irian Jaya are distinguished into about 250 sub-groups, although they all belong to the Melanesian race, and are related to the people inhabiting the islands along the southern rim of the Pacific. The Negritos are believed to have settled on the island first, probably some 30,000 years ago, followed by the Melanesians. The people of the central highlands still maintain their ancestral customs and traditions, and are virtually untouched by alien influences.

Most of the changes have so far taken place among the coastal people, who are being subjected to ever increasing contacts with the world outside. This process of change is being accelerated by the work of missionaries, who have been working for many decades among the local populations. The people of the north and west are mostly Protestants, while those of the south and of the hinterland around Enarotali are Roman Catholics. Those around Fakfak and the Raja Ampat Islands are mostly Moslem. Animism is still practised by isolated tribes in various parts of the province.

Although Irian Jaya is famed for its Bird of Paradise, the province's fauna is not particularly rich. Almost all the animals here are of the Australian fauna type. Copper, oil, timber and sea products like fish and shrimps are among the province's main products.
