For those who would like to visit Pakistan, I can summarize the following points based on my experience: 

1.  Pakistan is a rather strict Muslim country, especially on the outskirts. The streets are full of men; all merchants and labors are men. Women always stay home. Going out in public are women in veil, which reveals only their big beautiful eyes, or pre-teen girls walking to schools.
2.  Pakistanis, especially men and children, are super friendly. They usually smile and greet you. Most of them like being a model. When seeing a tourist holding a camera, they always ask him or her to take their photos.
3. Actually, Pakistan is a peaceful and beautiful country. It is not as frightening as what you have heard from the news. It is even safer than many neighboring countries.
4. Young Pakistani men, especially in the North, are very good looking, with a perfect mixture of Middle Easterner, Westerner, and (a bit of) Chinese. They will remind you of Johnny Anfone or Mario Maurer but with darker look and hair from sideburns to chin and above the upper lip. 
5. Young Pakistani girls in the North are equally good looking. They will remind you of Pinky Sawika. You can find them anywhere (If they are fully grown, their beauty will be hidden under the veil.)
6. The weather up north is very cold. I went to “Gilgit-Baltistan” in the northernmost part, with the border next to China, India, and Afghanistan. Moreover, it is surrounded by three Asian ‘giants’ – Himalaya, Hindukush, and Karakoram Mountain.   
7. I visited Pakistan at the end of October, which was fall season. Along the way, I saw the foliage and clear blue sky. The weather was cold. I went to bed in the temperature below ten every night and woke up with the vapor coming out of my mouth. People liked to have a sunbath all day long without caring about UV ray.
8. At that time, one THB was converted to three PKR. This was different from the conversion rate of neighboring country like India, one THB for two INR. The tourists can exchange the currency at the airport or some banks. (Please ask the tour leaders for recommendation.)
9. People there live a simple life. They buy things at the market or small grocery stores with cash while credit cards and debit cards are used in big cities or large shopping malls only.
10. Those who feel like a “nobody” in Thailand will suddenly become a celebrity there. Every day, at least four or five people asked me to take photos with them. Some took a selfie while others shook hands with me and asked their friends to take a picture. The funniest thing happened on the last day of my trip. I asked the chauffer to stop the car to take a photo of the river. Then, almost twenty locals picnicking there left their meal and flocked toward me to take a photo with me. One person put a guitar in my hand as a prop while another gave me a pair of sunglasses. A guy even arranged the queue to take a photo with me.
11.  The best season to visit the North is summer, April to July. However, the temperature is still cooler than Thailand.
12.  With the strict Muslim lifestyle, an unmarried man and woman cannot be alone together. All tour leaders are male. That is why it is hard for female tourists to travel alone. For any ladies who would like to do so, finding a companion can be a good option. Moreover, you should leave hot pants or mini-skirts at home.
13. The only airline flying from Thailand to Pakistan is Thai Airways International, which takes almost five hours. Arriving there at late night, you can rest either at the airport or Islamabad before travelling to Gilgit. On the way back, you will arrive in Thailand at 6 a.m. The time there is two hours slower than Thailand.
14. While staying there, I ate chicken curry with (long-grain) rice and thick vegetable curry with flatbread called Japati or Naan almost every meal. Trust me …. It tastes a lot better than Indian food.
