Read the Golden Triangle's history at the Hall of Opium
Sop Ruak, Chiang Saen
Where Thailand, Laos and Myanmar meet on the Mekong, a sober museum tells the story from poppy field to heroin trade.
What it is
Sop Ruak, in Chiang Saen district, is the stretch of Mekong bank where Thailand, Myanmar and Laos meet. On the hillside above it, the Hall of Opium, run by the Mae Fah Luang Foundation, is entered through a 140-metre tunnel carved with reliefs of anguished figures, which opens into a full-scale recreated poppy field. The galleries then run in order: Chinese trade ledgers and colonial-era opium dens, the scales and pipes of the hill country, and the route from poppy to refined heroin that funded decades of conflict along the border. Captions are in English throughout.
How to do it
It opens Tuesday to Sunday, 08:00 to 16:00, and foreigners pay 200 baht. Allow at least two hours. Most visitors come on a Golden Triangle day tour from Chiang Rai.
Good to know
It is closed on Mondays. Do not confuse it with the much smaller House of Opium in Sop Ruak village, a couple of kilometres away.
