Phobjikha, at an altitude of 2900 m, falls under the district of Wangdue, Bhutan, and lies on the periphery of the Black Mountain National Park. The valley boasts two beautiful meandering rivers, Nakay Chhu (Chhu Naap-black water) and Gay Chhu (Chhu Karp-white water). According to a local legend, the two rivers actually represent a snake and a boar. The two animals once raced each other with an agreement that if the snake (Nakay Chhu) won, Phobjikha valley would be able to grow rice, but if the boar won, then rice could never be cultivated in the area. The snake lost since it had to meander all the way during its journey. Rice cannot be cultivated in the valley even today.
Perched on a small hill that rises from the valley floor, the Gangtey Monastery is the only Nyingmapa monastery on the western side of the Black Mountain’sGangtey valley, Bhutan and also the biggest Nyingmapa monastery in Bhutan. The Monastery is surrounded by a large village inhabited mainly by the families of the 140 Gomchens who take care of the Monastery. Gangtey was founded by Pema Trinley, the grand son of Pema Lingpa, the famous Nyingmapa saint of Bhutan. In 1613, Pema Trinley establish the monastery and became the first Gangtey Tulku. The religious traditions of Pema Lingpa still taught there. The second Tulku, Tenzin Legpa Dondrup (1645 to 1726), enhanced the size of Gangtey while keeping up good relations with Drukpas, and rebuilt the monastery in the form of a Dzong.
