Chiang Khong, is a small, peaceful district on the bank of the Mekong River opposite Huaixai, Lao PDR. It is about 115 kilometers from the provincial seat, or approximately 55 kilometers to the east of Chiang Saen on Highway No. 1129. Chiang Khong is noted as the place where Pla Buk, giant catfish, is cultivated. The Chiang Khong Fishery Station is able to inseminate and breed Pla Buk, the largest fresh water fish in the world and fingerlings bred here have been released in several rivers. It should be noted that the fishing season is from mid-January to May.

Sightseeing trips by boat are available to view the scenery and life styles along the Mekong River. An additional attraction is a visit to Ban Hat Bai, a Thai Lu community noted for making beautiful local fabrics.
