A North-East (Isan) province, bordering Laos. Located in the Mekong Valley, bordered by Ubon Ratchathani, Yasothon and Mukdahan provinces.
The province is located in the Mekong valley. A long footpath along some of the river allows people to enjoy the view. In dry season, from February to May, water in Mekong River descends, and allows islands to appear. Such famous islands include Kaeng Tanglang at Si Sombun Village, close to Amphoe Chanuman, and Kaeng Hin Khan at Ban Hin Khan, 30 kilometres south of Amphoe Chanuman. The other two rivers in the province are the Lam Sae Bok and Lam Sae Bai.
