The world-famous Golden Triangle refers to the point where the borders of three countries -- Laos, Thailand and Myanmar meet. It is located about 8 to 9 kilometers north of the old town of Chiang Saen and lies along the road which runs parallel to the Mae Khong River. This area is locally referred to as Sop Ruak.
A very interesting place to visit within the Golden Triangle Park is the ‘Hall of Opium’, where tourists can learn about a wide variety of issues related to opium such as its history, its natural properties, its uses, stories of the opium wars, and the problems caused by opium (along with a mild message about refraining from opium smoking and trading).
