Sprawled across the southern half of exotic Borneo island, Indonesian Kalimantan offers nature enthusiasts and adventurers once-in-a lifetime river journeys. Wildly beautiful Kalimantan is predominately swathed in some of the world’s oldest, most biodiverse rainforests, home to indigenous ethnic communities and endangered endemic species, including the clouded leopard and iconic orangutan.
On epic Borneo cruises, board a klotok (a converted traditional houseboat) and explore jungle-engulfed rivers that reveal Kalimantan’s remote primeval forests, Dayak ethnic culture and incredible wildlife. The most unforgettable experience is encountering orangutans in one of their few remaining natural habitats. An orangutan Borneo river cruise brings you to one of several national parks, but especially, the most famous, Tanjung Puting and its acclaimed conservation camp, where orangutans can be spotted swinging through the trees.
