Traditionally known as Kurtoed, makes the country very different from the modern world unlike the western part with lot of untouched cultural heritage and natural environment. Terrain landscape with lot of small settlements is inaccessible by road, and folks there have to get on foot with their farm products on their back. This is the most densely populated region in the country with least development.
Northeastern region called Merak and Sakten living on Yaks have unique culture, very different from western Bhutan. These nomads travel to south in winter with their sheep, especially in Trashigang still black Yak-hair hats hanging down their head.
