safe place to stay in Pakistan?

[Trango Towers]

How do I get Pakistan train tickets from Islamabad to Quetta lol?
I want to travel and see pk's trains also

I want to see Balakot because of a friend of mine who was in HK but now resides in pk
Like give him a surprise

What is needed to pass the pk china border btw?
I have a British passport so I guess i will have to apply for some type of visa

Train tickets are easy. Just turn up at the station. But first class they are cheap and travel us nice experience. Take your own food but hit beverages are fine. Do not eat the food on the train. Personal bad experience.
If your friend lives in Balakot he will take you around the nice places.
Pakistan China border requires a visa. Costly I think. If you belong to the northern areas then you just require a pass.
