The Gangteng Monastery, also spelt Gantey Gonpa, bounded on the west side by the Black Mountains (Bhutan) (range above 5,000 metres (16,000 ft) elevation) is located on a spur amidst the Gantey village, overlooking the vast U-shaped glacial Phobjika Valley, which is at an elevation of about 3,000 metres (9,800 ft) and which has marshy land. The Nake Chuu river runs through this valley. The monastery commands striking views of the Phubjika Valley below. The Black Mountain Region is inhabited by nomadic shepherds and yak-herders.

Wangdue Phodrang, the district headquarters, is 45 kilometers (28 mi) from the Nobding village in the Phobjika Valley on theTrongsar road from where a short diversion road leads to the Gonpa. It is 75 kilometres (47 mi) to Thimphu, the capital of Bhutan. The Gonpa lies on the popular trekking route of the ‘Gangte trail’ which starts from the bottom of the Phobjika valley, passes through the Gangteng Valley, then climbs up to the Gangteng Gonpa, then goes through the Kumbu village on the east of the Gangteng Gonpa, passes through Gedachen, Khebaythang, the Kilkhorthang villages and finally touches the Kungathang Lhakhang
