Hi, One of the highest lakes in the world is the Gurudongmar Lake located at an altitude of 17,800 ft, in the Indian state of Sikkim. It is a lake that is considered to be sacred by both the Buddhists and Hindus. But the name of the Lake is named after Guru Padmasambhava, the patron saint of Bhutan. He is also known as Guru Rinpoche and was the founder of Tibetan Buddhism who visited this pristine lake in the 8th century. It lies to the northeast of the Kanchenjunga range that is only five km south of the Chinese border. Gurudongmar lake temperature in November is considered as the best time to visit by the tourists as the clear waters of the lake can be seen from June to November without any accumulation of ice. Snowfall starts only by the end of November, backed up by snowstorms.
