In 1998 I travelled to one of the least visited parts of the world, Irian Jaya, the western half of New Guinea. Imagine an area twice the size of the UK, put a mountain range down the middle with peaks bigger than in the Alps, then cover with dense rainforest and large rivers. It's not really a suprise few people travel here and even fewer get into the interior. Here are a few of the best pictures from the highlands.
