Gurdwara Guru Dongmar in North Sikkim.
Guru Dongmar is a lake at a height of 18,000 feet alongside a glacial peak known by the same name. The lake remains frozen most of the year due to heavy snowfall for almost six months each year. Guru Nanak visited the place during his third Udasi in order to solace the Karma-pa Nying-ma-pa sects then being hounded out from Tibet by the Ge-lug-pa sect. Many from the Karma-pa Nying-ma-pa sect were the followers of Guru Nanak, as their Head Lamas became Guru Nanak's followers in Kailash ManSarovar area after being impressed by Guru Nanak's discussions with the famous Sidhas of the age.
