Four hours away from Gangtok, lies the kingdom of snow i.e. the Nathula Border-the famous gateway on the silk route on the Indo-China Border. After a slow and steep drive through the mountains-which change their colour from a sumptuous green to a barren black to a snowy white, one reaches the Nathula border-along with many tourists who regularly throng this major attraction in Gangtok. On the to Nathula, lies the Tsomgo Lake- an un-rippled glass sheet in which the snowy mountains silently admire their own reflections. To beat the cold, duck into the café run by the army and treat yourself to coffee and chocolate. At Tsomgo, treat yourself to hot noodles at many of the small eateries dotting its banks.
