Also, some of the other things you should do while in Dharamshala, Dalhousie and Amritsar trip.
Do experience momo's in Dharamshala, 10 pieces for Rs.60/-
Do drink tea at mall road of Dalhousie
In Amritsar do shop for Kada, Chuda if you are married for your wife and have langar in golden temple.
Hope you might have liked the backpack trip. If you need any suggestions while visiting Amritsar,Dalhousie or Dharamshala feel free to ping it's kind of second home to me.
