This beautiful glacial valley lies at 2900m. After climbing up through dense forests dripping with lychen, the wide, open expanse of dwarf bamboo can come as a surprise. The valley boasts two beautiful meandering rivers, Nakay Chhu and Gay Chhu. Perched overlooking this beautiful, almost flat valley is the village and monastery of Gangtey. As well as the black-necked cranes that roost here in the winter, there are also barking deer, wild boar, red fox, leopard and Himalayan black bear.
Chendebji Chörten, built in the style of the great Bodhanath Chöten of Nepal, was constructed by Tshering Wangchuk son of Yon-Say and the Mahasiddha Zhidag in accordance with the prophecy of the Second Gangteng Tulku Tenzin Lekpai Dhundrup in order to subdue harmful, anti religious demons. It is located 41 km west of Trongsa in Bhutan at 2430 meters in elevation.
A Sambha Lhundrup Molam Chenmo festival is held there annually from the 21st to the 25th day of the 9th lunar month of the Bhutanese calendar.
