Around 60km to the east of Ubon Ratchathani at the confluence of the Moon and Mekong Rivers, this sleepy town offers a quiet escape from the big smoke of Ubon Ratchathani.

The point where the two rivers meet is known as the 'Two Colour River', and sure enough, depending on the flow and heights of the two rivers, a distinct difference in colour is evident from the river's bank due to the differing sediment levels in the Moon and Mekong Rivers.

Aside from the two colour river, there is nothing much to see in Khong Chiam itself, although it is an excellent base from where to visit the nearby Pha Taem National Park, the border town of Chong Mek and two nearby dams.
