At the mouth of the Mun River, Ban Woen Buek, just a 5-minute drive from Amphoe Khong Chiam, is an amazing point. The Mun River runs into the Mekong, so you can see two rivers, in two different colours – "Song Si" means two colours - blending together. The Mekong River will be reddish brown while the Mun River is rather blue. Tourists can see the colour difference from Wat Khong Chiam and Ban Huai Mak. April is the best time to see this. A boat cruise service to explore the rivers, Kaeng Tana, Ban Woen Buek and Pha Taem, as well as shopping in Laos is available.
