Initially, after crossing a bridge across the Bumtang Chuu, the road goes down to Dechen Pelrithang (a sheep rearing farm, at an elevation of 2800 meters ), then passes the famous Mebartsho gorge (the place in which treasure was found by Rimpoche in the river at deep depths under severe visibility constraints diving down with a lighted butter lamp, and hence named as the "Blazing Fire Lake") of the Tang valley.
