We went to gangtok last year during November to see snow fall.It was an amazing experience.
Gangtok is very beautiful tourist destination.The whole city has beautiful unique scenery. It is so well maintained, neat and clean. The locals are so well behaved and civilised.
Snowfall is the best part. Trekking in snow is such an amazing experience.
I suggest,
Everyone should go to gangtok at least once.It is such a peaceful place . It is so enjoyable experience
