Gurudongmar Lake, at 17,800 feet above sea level, is not only India's but also the world's highest lake. Gurudongmar Lake, widely regarded as a sacred spot for Hindus, Sikhs, and Buddhists equally, is one of the most amazing sites to visit in Sikkim during the summer. The spectacular blue, green, and grey colours of this lake, which is surrounded by snow-capped peaks, never cease to amaze nature enthusiasts and adventurers.
