The Kumbu Lhakhang is located 2 kms to the north eastern side of the Gangtey Monastery. The epithet Kumbu could have been derived from Kumbu Bja which is the name of a cliff above the village. The name "Kumbu" have been a derivative name from "Kubum" meaning a hundred thousand statues. The local people have a strong believe that the cliff actually contains a thousand statues.

The temple was originally built as a bonpo temple by Zhabdrung Tshanden Dulwa in the thirteenth century. He was a bonpo lama. Another temple was founded by him at Sewagang in Nyisho in Wangdue Phodrang. The temple is believed to be the residing place of the Ma Sripa Gyalmo, the Bonpo religious protectors. Kumbu Temple offers several interesting statues, and many historical artifacts and scriptures.

There are two routes to reach Kumbu Lhakhang. One is an unpaved feeder road passing below the Shedra and once you reach there you have to walk up about half an hour from the road point to the temple and the other is a shortcut passing through the Kunzang Chholing Shedra which directly leads you towards the temple.

The Kumbu Lhakhang is the best to visit in October to December and from April to June. During monsoons roads are muddy and it is not suggested to visit this place then. In winters place is covered with snow and roads are inaccessible.

This two storied temple is situated in front of five houses forming a part of the Kumbu village. It is believed that the Lama tied a goat and a sheep together to let them show him a place where he would build the monastery. The two animals led him to a place known as Kumbu Lhazhi Tsawa where the temple was later built.
