Tsomgo Lake, also known as Changu Lake, is a stunning glacial lake in Sikkim, India, renowned for its breathtaking beauty and changing colors with the seasons. The lake is generally accessible to tourists, but permits are required, especially for foreign nationals. Accessibility can be challenging due to the high altitude (around 12,313 feet) and steep, winding roads; it is advisable to check road conditions, especially during winter when heavy snowfall can lead to closures. Both solo and guided visits are possible, with guided tours often providing valuable insights into the local flora, fauna, and culture. The best time to visit is during the summer (April to June) and autumn (October to November) months when the weather is relatively mild and the lake is not frozen. The approximate cost, including permits, transportation, and basic expenses, can range from ₹2,000 to ₹5,000 per person, depending on the mode of transport and tour package. A typical visit duration is around 2-3 hours.
