The Hall of Opium is located in the Golden Triangle Park, a 40-hectare site near the Mekong River in Chiang Saen district of Chiang Rai. The Hall of Opium houses a 5,600 square-meter permanent exhibition on the history of opium and other narcotic drugs. It was created to help reduce demand for drugs through education, designed to be both fun and educational, or learning through edutainment.

The Hall of Opium grew out of the Princess Mother’s desire to educate people on the background of opium. This region, covering parts of Laos, Myanmar, and Thailand, is infamous worldwide for its poppy fields, drug smugglers, and opium warlords. From the 1960s to the early 1990s, the Golden Triangle supplied most of the world’s heroin. The Golden Triangle has become a leading tourist destination, welcoming a large number of visitors each year.
