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.

Doi Tung

Doi Tung is located in Mae Fa Luang District and can be reached by taking Highway No.110 for about 48 kilometers and turning left onto Highway No. 1149, an asphalt road leading directly to Doi Tung. The route winds through beautiful scenery with many interesting sites including the Doi Tung Palace (Pra Tamnak Doi tung), the Mae Fa Luang Garden and Akha and Muser tribal villages. IN addition to scenic lookouts, the most notable attraction is the Phra That Doi Tung Holy Relic, an old religious site atop the mountain.
