These destinations are often included together in North Sikkim itineraries, yet each has its own charm and seasonal personality. One of the most common questions travellers ask while planning a trip is about the best time to visit Lachen and Lachung.
Because of their high altitude and sensitive weather conditions, choosing the right time is crucial for a comfortable, safe, and visually rewarding journey.

Why Timing Matters for Lachen and Lachung
Lachen and Lachung are located at elevations above 8,500 feet, making them highly dependent on weather and road conditions.
