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.
