The tremendous outspread of jungles and wilderness, which are so rich in natural resources as timber, gas, oil and coal as well as scenic beauty - are comparable to that of a continent alone. Focal point for most visitors is the mighty Mahakam river, which meanders through thousands of kilometers through one of the worlds largest tropical rainforests, from its head water near the center of the island.The twenty main Dayak tribes - once feared as headhunters have their homes in this river basin, A remarkable varieties of plants and animals life including the famous fresh water dolphins which often accompany boats along the river make a visit to Kalimantan an enthralling venture to a different world. In year to come the Mahakam river trips are most likely to have a more modern outlook with modern crafts and all possible amenities. Unfortunately under such circumstances the Dayak village would have last their primitive charm, and a cliche scene of souvenirs shops would cluster along the riverside.
