About Chiang Rai

Chiang Rai (เชียงราย)
The city was founded by King Mangrai in 1262 and became the capital of the Mangrai dynasty. Subsequently, Chiang Rai was conquered by Burma and remained under Burmese rule for several hundred years. It was not until 1786 that Chiang Rai became a Chiang Mai vassal. Siam (Thailand) annexed Chiang Mai in 1899, and Chiang Rai became a province in 1910.
Chiang Rai province’s Golden Triangle bordering Laos and Burma was once the hub of opium production which had much influence on cultural practices and lifestyles. Until this day, entire clans live together in bamboo houses and each village has its own individual character.

Climate
There are three seasons – the hot season from March to May, the rainy season from May to October and the cool season from November to February. In the cool season, the temperature may drop to 13 °C at night. It can be lower in the mountains.
