Located along the way to the Tang village over the feeder road under Bumthang valley, it takes thirty minutes drive to the Mebar Tsho from the Chamkhar town.
Mebar Tsho is considered one of the most sacred sites in the region as it relates to the renowned treasure reveler, Terton Pema Lingpa-incarnated disciple of Padmasambhava who discovered treasure from the lake somewhere around late 15th century.
It is believed that Terton Pema Lingpa had a vision about hidden treasures to be found at the foot of Tang Valley which was indicated by Guru Rinpoche many centuries before. Since the people of tang and the local ruler was cynical about it, he held a butter lamp in his hand, he jumped into the lake, remained under water for a long time, and he re-emerged holding a chest and a scroll of paper in his hand and the butter lamp held in his hand still burning bright. Thereafter, the lake came to be known as Mebartsho (the burning Lake).
Today this small fresh water lake is a sacred pilgrimage place for Bhutanese with bright multicolored prayer flags surrounding the place and on auspicious days people go and offer butter lamps on the lake. Many tourist visit the site to observe spectacular beauty of the place and it is also an important site for historians.
