My Pakistani friend told me to visit Pakistan and said it is really cheap?

Bonjour from Chitral,

No idea about the train from China into north Pakistan, though buses and coaches make it from Kashgar and Tashkurgano to Sust ( Hunza ).

If any trekking itinerary is not included, 1500 to 2000 US $ seems a practical amount for 3, 4 weeks in Pakistan, while staying in mid range guest houses and using mostly the public transport in North Pakistan and Chitral.

Ciao,

There are no trains travelling from China to Pakistan, and there are no trains in Northern areas of Pakistan ( Gilgit/Baltistan etc).

I guess taking the buses along the Korakaram highway would be the way to go. I am more interested in the natural sites and mountains in north Pakistan. If I stayed in really cheap hostels and took the bus around to the natural sites in north Pakistan...do you really think it will cost about $1,500 - $2,000 US? That is not cheap! I have traveled for 3 weeks in China and spent way less than that. There much be a cheap way to see Pakistan for only about $1,000 US for 3 weeks or more. I don't mind sleeping on the floor or in a ghetto place with bugs. I am not like most people. I am not picky at all. I just want to experience the countryside there and I am willing to sacrifice comfort and luxury.

There are plenty of cheap rooms around, and you won't have to sleep on the floor, you should be able to get a decent single for $3-4 in most places. I've just returned from 6 weeks touring Northern areas with my wife on the bike and we didn't pay more than 700 Pkrps anywhere for double en-suite, ( except for PTDC, which we had to use on 2 occasions). Excluding travel costs you could easily live on $10-15 a day, if your happy eating in local places !

I lived well in Nth Pakistan for $20 a day.

Yeah,you can easily live on 15$ per day basis.The food is quite cheap & you can stay in hotels for 4/5$ per night.

No train from China to anywhere in Pakistan including Northern areas.

This is very good news! I don't mind eating the local food and mingling with the locals. I really want to stay away from the cities and stick to the countryside, near the mountains and valleys. The northern areas and the Jumuu and Kashmir areas look the most interesting to me. I thought about Kaghan Valley for Lake Saiful Maluk, Dungagali, Khyber Pass, Kailash valley in Chitral, Khunjerab Pass in Hunza valley, Nanga Parbat Base camp (Fairy Meadows), Kashmir valley, K2 base camp & Gondghoro la. There are so many amazing places to see here. I should be able to see most of these places if I traveled there for a month or so. Which places are the must sees?

Forget Azad Kashmir, you won't get in without NOC, and that probably applies to Kaghan valley as well now. Khyber pass has been closed to foreigners for some years so I would suggest you stick to Gilgit/Baltistan. Chitral/kailash is still possible but you will be obliged to have a police escort 24/7 during your stay there, even sleeping outside your hotel room door ! Personally, I felt very uncomfortable being constantly accompanied by armed constables, nor did I feel that it was necessary.

@uselessbaba: That sounds terrible! I wouldn't want to deal with such a hassle with the police or military during my trip. I will stick to the areas you mentioned. That being said, have you been to both of these areas before? What are some must sees in these places? I want to see some big mountains and some valleys and natural lakes. Things like this. Maybe some small towns or villages in the countryside for the cultural experience as well. Thanks for the information. I hope to hear from you soon.
