The story behind it
The Barito begins in the Müller Mountains in Central Kalimantan and flows south across Borneo. It is a wide river: on average 650 to 800 metres, and about 1 000 metres near its mouth. Large boats can travel about 700 kilometres upstream, and ocean-going ships sail as far as Banjarmasin. Very early each morning a floating market comes to life where the Kuin River meets the Barito in Banjarmasin. Women traders sit in small boats called jukung and sell vegetables, fruit and fish until about seven o'clock, when the market slowly empties. Below the long Barito Bridge lies Bakut Island, where visitors can watch proboscis monkeys. The Barito region also has a surprising link to Africa. The Ma'anyan language spoken here is a close relative of Malagasy, the language of Madagascar, because people from Borneo reached that island across the ocean long ago.
