The Hall of Opium is an educational facility located within the Golden Triangle Park in Chiang Rai, Thailand, dedicated to the history, production, and sociological impact of opium. Established under the patronage of the Mae Fah Luang Foundation, the museum chronicles the origins of the poppy plant and the historical opium trade that once dominated this border region. Visitors traverse a 430-meter tunnel leading into the exhibition space, designed to simulate the disorienting effects of drug addiction. The museum provides detailed accounts of the global historical timeline, spanning the Opium Wars to the eventual suppression of the drug trade in northern Thailand. It documents the transition of local hill tribe agriculture from opium cultivation to sustainable alternative crops. Exhibits include authentic smoking paraphernalia, historical documents, and interactive displays detailing the physiological consequences of substance abuse. The facility serves as a focal point for the regional campaign against narcotics and illicit trade. It is situated on a 128-acre site overlooking the Mekong River and the convergence of Thailand, Myanmar, and Laos.
