A small town on way to Yumthang, Chungthang Valley stands at the confluence of the rivers Lachen chu and Lachung chu. The North Sikkim highway bifurcates from here with one road leading to Lachen and the other to Lachung. Chungthang valley is considered to be a holy place which has been blessed by Guru Padmasambhava, the patron saint of Sikkim. There is a rock here which to this day bears the hand and footprints of Padmasambhava. From a small opening in the rock there is continuous flow of mineral water. There is a small patch of land here from which grows paddy every year. The nature defying miracle is believed to be the blessing of Guru Padmasambhava who sprinkled a handful of grain on the spot which has sprouted paddy ever since.
Chungthang is a good place to halt before one takes off for the more alpine regions of Lachen, Lachung and the Yumthang Valley. Chungthang is mired in myths and legends, one such being that this is the place from where the word ‘Demazong’ [the hidden valley of rice, as Sikkim is known] first originated.
