One of the many boards at Nathulla Pass – The Indo China Border atop 14000 feet , near Gangtok. Sikkim. If you plan to visit here, please ensure you have a permit. The weather generally dips to single digits and somtimes in the minus and oxygen supply is rather low here. It is better to start your journey well ahead as roads from Gangtok close by 1 pm towards Nathulla. This is my second visit here and personally if you ask me, it is just another tourist attraction , but the journey is something worth savouring. You can meet the Indian army here and if you would like to interact with the Chinese , then these phrases may come in handy.
