Mebartsho is considered as one of the most sacred sites.'Burning Lake' is actually a deep pool in the gorge of Tangchu river. Although not much to see for tourists, it is a sacred site where Pema Lingpa had retrieved sacred religious treasures from within this deep pool in the early 16th century. It is located along the road to Ura or Tang within a walking distance of 5-6 minutes.On auspicious days people offer butter lamps at the lake. Hundreds of prayer flags are strung through the trees and thousands of tiny stupas are crammed into the rocksmake. It is a nice place to stop and reflect.
