Pelela pass at 3300m is an important dividing range that separates Western Bhutan from Central and Eastern Bhutan. Crossing this important Pass, one may enjoy the pastoral feeling as you drive deeper into the valley with meadows where sheep and yaks graze. The bamboos that grow plenty on these hillsides are trimmed by yaks. Yaks love the dwarfed bamboos. If you are a bird watcher, look out for the specialty called the Wren Babbler taking refuge underneath those bamboos. In the months of April-June, the hillsides are painted with the rhododendron blooms. Trongsa, the sacred and the temporal heart of the country is the first district that you will come across.
This region that spans from 2,600-4,500m is the religious heartland of the nation and home to some of its oldest Buddhist temples and monasteries. Tales of Guru Padmasambhava and the tertons (“religious treasure-discoverers”) still linger in this sacred region. The district is sub-divided into the four blocks of Chokhor, Chumey, Tang and Ura. The valleys are broad and gentle carved by the ancient glaciers. The wide and scenic valleys draw a large number of tourists each year.
