The Hall of Opium at the Golden Triangle Park houses several sections to be explored and various exhibitions to be contemplated. For example, the 5,600 square-meter Hall of Opium presents An Invitation to the Mysterious World of Opium from Darkness to Light, the history of opium as of 5,000 years ago from its natural properties to its uses. It traces opium's global journey through trade routes in the age of imperialism, culminating in the Opium Wars-an event that disgraced both winners and losers that led to the fall of the Manchu Dynasty. It also features Siamese wisdom in confronting the West and the eventual control of opium problems.

Chiang Khong

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.
