I have been to Manali many times and I would like to say its a beautiful place created by god. Snow capped mountains, roaring sound of beas river and chilling temperature really takes you to the heaven. There are so many adventures which you can do there for instance river rafting, paragliding etc.
From there you can continue your journey to Rohtang pass its a place which is open for tourism for only six months rest six months its completely covered with snow. At last I would like to say Manali is a Switzerland of India.
