Hey, 14 days is ideal to cover all the beautiful places in Himachal. However, have you decided which side to visit? You cannot visit all of Himachal in 14 days. If you can share which side you are planning to visit (like whether Shimla-Sangla-Kinnaur-Manali or the Leh-Ladakh side or Spiti or even Dalhousie side), then I can help you out.
Great, after delhi and chandigarh,you have many places to see in himachal, its depends on you which one you prefer,
1. manali and near by places like, tosh,malana,parvati velly,
2. shimla and kufri
3. mcleodganj
