Road connectivity reached Bhutan in the early 1960s and until then mules, horses and yaks were used for transportation. With the inception of tourism, Trekking routes in Bhutan are developed along the ancient routes- passing through the valleys, gradually ascending to the mountain passes and descending to a whole new valley.

While the exclusive Himalayan flora and fauna inhibiting the majestic mountains and awe-inspiring glacial lakes create a strikingly exclusive destination, a harmonious coexistence of the scenic beauty with modern human settlement in a sustainable manner is an enthralling fact of a country driven by principles of Gross National Happiness.
