Visiting the renowned Golden Triangle is a must to complete the trip to Chiang Rai province! This is the famous location where the borders of Thailand, Laos, and Myanmar meet in the middle of the Mekong River. The Golden Triangle was formerly known as the world’s major producer of opium, which was later improved thanks to the works of the Royal Projects. Reaching the Golden Triangle where Thailand, Laos, and Myanmar join is easy as it’s only 9 kilometers north of Chiang Saen, by taking the road parallel to the Mekong River.
