When you are visiting Uttarakhand, make sure that you are carrying the right kind of clothing. Uttarakhand clothing depends upon the season during which you are visiting the state. The weather in Uttarakhand is quite pleasant, although at places it can get pretty hot during the summers. Hence, it is advisable to carry loose cotton clothing for the summers.
Avoid any kind of body hugging or synthetic material if you are visiting during summers. But, if you are going to the hill stations like Mussoorie, Auli, etc. then don't forget to carry woolen clothes even during the summers as it is pretty chilly in the hills, even during the summers.
As for the winter season, it gets extremely cold during the winters and almost all the hilly areas experience heavy snowfall. So, take some heavy woolen clothes with you, if you plan to visit Uttarakhand during the winters.
