The Bi-coloured River , or the Mun River's alluvium, is the place where two rivers join: the brown Mekong River and the blue Mun River. It is located in Khong Chiam District, about 84 kilometres from Ubon Ratchathai city centre.

Pak Mun Dam was constructed from stone and reinforced with clay soil. It has a width of 17 metres and a length of 300 metres. The dam facilitates agriculture and generates electricity. It is located approximately 75 kilometres from town, or about 6 kilometres from the area where the Mekong River meets the Mun River. It is possible to travel along the top of the dam wall as a short cut from Klong Chiam District to Amphoe Sirinthon without driving back to Phibun Mangsahan District. Cruising along the beautiful Mun River is possible from the end of the dam to the Bi-coloured River , where the Mun River joins with the Mekong River.

Pha Taem National Park covers an area of 140 square kilometres, where plateau and hills dominate the park's landscape. There are sheer cliffs, which resulted from earthquakes. Most trees are of the deciduous dipterocarp forest. Irregular shaped sandstone is found scattered throughout the area. Beautiful flowering plants grow in the rocky ground. Travelling here can be accomplished from Klong Chiam District along Highway No. 2134, followed by Highway No. 2112, and then turn right for another 5 kilometres. Places of interest within the park are:

Sao Chaliang is on Highway No. 2112, about 11 kilometres from the office on the route to Pha Taem. Sao Chaliang is a natural formation of rocks sitting one upon another forming a mushroom-like shape. Fossils of sea shell, pebbles, and sand grains can be seen in big stone slabs, leading academicians believe that this area must have been a sea bed about a million years ago.

Pha Taem and Pha Kham are located near the national park headquarters. On the cliff's surface are prehistoric paintings dating back to 3,000-4,000 years ago that reflect the ancient way of life of the people who once lived in the area. These painting depict scenes of fishing and rice farming. Figures of people, animals, hands and geometric designs were also depicted.

Tham Mut , at Ban Sa Som, is a cave some 4 metres wide and 6 metres high. Inside there are many carved Buddha images, indicting that it used to be a place for religious ceremonies.

Soi Sawan Waterfall is 30 kilometres form Khong Chiam District. It is a big waterfall cascading from two sides of steep cliffs about 20 metres high.

Saeng Chan Waterfall is only 1 kilometre from Thung Na Muang Waterfall. It is a very beautiful waterfall with a special characteristic of its own-water cascades down through a rock pile resembling a full moon shining onto the world.
