Hello
You can surely see snowfall if you are headed there in the first few weeks of Jan. But you can definitely see snow laden peaks throughout the month.
Hello yasmin,
If you are planning for Auli then december to february is an ideal time for visit. The chances of snowfall is high and you can find the ropeway car ride and skeeing in Auli Happy travelling:)
Hey Yasmin co-incidentally just yesterday i have written my first travel blog on tripoto and that is on my trip to Auli only. Just have a look at it and you will get all your answers. For any further query you can ping me.
December is indeed a good time to visit Auli. Being the Skiing capital of India, you must visitthis place for some snow fun. However, it is suggested you visit during the end of the month as the chances of snowfall during this time is higher.
