Guys if you want to feel the chill of winter then I suggest you to visit Manali now. I have visited it 2 years before at the same time. Guys belive it its a awesome feeling snow & snow everywhere its feels like it heaven. Evening is so wonderful slient and cool.if you are lucky you can see snowfall also.
Here you can visit local market, hadimba temple, buddhist temple, manu temple etc.
And must visit solang valley if roads are opened. You can enjoy adventure sports there and have fun there.
We stayed there in snow valley hotel its comes in good budget and services there are good.
You can reach there from any part of India by train and volvo buses.
What are you waiting for go and have fun there.
