The Two-Color River, also known locally as “Don Monorom” or “Dong Chiam,” is located in Ban Dong Chiam, Khong Chiam District, Ubon Ratchathani. It marks the confluence of two major rivers: the reddish Mekong River flowing from Laos, and the greenish Mun River from the heart of northeastern Thailand.

At the meeting point, the waters of the two rivers run side by side without blending immediately, forming a visible line between the colors—a captivating phenomenon that attracts both local and international tourists.

There are viewing platforms and photography spots, as well as boat tours that allow visitors to explore the confluence closely. The area is particularly famous for its scenic sunrise views, especially during the cool season. Visitors can also continue their journey to nearby attractions such as Pha Taem National Park.

Amenities include local restaurants, souvenir shops, and various accommodations ranging from homestays to riverside resorts, making it ideal for either a day trip or an overnight stay to fully enjoy the natural surroundings.
