Gasa is most famous for its Layap people, and for the Snowman Trek, one of the most challenging treks in the Himalayas. Gasa is bordered by Tibet to the north and by Thimphu, Punakha, and Wangdue Phodrang dzongkhags to the south. Gasa is divided into four gewogs:
* Goenkhamae Gewog
* Goenkaatoe Gewog
* Laya Gewog
* Lunana Gewog
National Council from Gasa
Formally, Gasa was a dungkhag under Punakha dzongkhag and it was made a separate dzongkhag at the beginning of the 7 th plan in 1992. It consists of four Geogs – Goenkhatoe, Goenkhamae, Laya and Lunana. Gasa lies on the old trade route to Tibet. The Gasa people take pride in the fact that the Zhabdrung entered Bhutan through Gasa and there are many sacred places and artifacts revered as being blessed by his presence and association. In fact, the map for the Geog as drawn by the community use landform associated with the Zhabdrung as reference point. For instance, the Phulakha (pass in the north) is where it is believed that the people of Gasa made their first offerings to the Zhabdrung who had camped there on his way into Bhutan.
