Within 2 days of time you can visit places like dhanaulti near to mussorie, Kufri near shimla, manali or dharamshala. But this depends upon snow availability, at present manali is experiencing its snowfall so i would recommend you for manali.
Hey Rahul, You can go to following places for snowfall and camping : 1)Kheerganga trek(One day trek, Parvati valley-Tosh, Malana, Kasol) 2)Triund trek (One day trek, Dharamshala-Naddi, Dalhousie, Macleodganj) 3)Prashar lake trek (One day trek, Mandi) 4)Kedarkantha trek (5 days trek, Uttrakhand-Dehradun, Rishikesh, Mussourie) Hope this would help you.
Depends on the mode of transport. since driving on hills takes time and most of the places r not directly connected. By self drive:
almora
binsar
lansdowne
mussorie
nainital
