According to forum posts, tourists from 175 countries can apply for a Pakistani visa online through the Nadra website. The process involves creating an account, filling in necessary information, and submitting required documents such as a photograph, passport, hotel booking, return ticket, and an invitation letter if applicable.

Travelers have noted that the required documents include a clear photograph, a copy of the passport, details of hotel bookings, and a return ticket. An invitation letter from a Pakistani national or a designated tour operator may also be required, especially for group tourists. For residents outside their home country, proof of residency or a work permit is necessary.

Some forum users mentioned that electronic signatures are not accepted; only scanned color copies of original signed documents are valid. Visa applicants might also need to provide additional documents like a No Objection Certificate (NOC) from their employer, as experienced by a user's friend applying from Dubai. The typical visa fee is USD 60, and the approval process can take up to 8 days, although delays can occur if submitted documents are unclear or incomplete.

According to forum posts, the processing time for a Pakistani e-visa can vary widely. Some travelers reported receiving their e-visa within days, while others experienced significant delays, with waiting times extending to several weeks or even months.

Travelers have called out several factors that may contribute to delays in e-visa processing. These include a high volume of applications, issues with the submission of supporting documents such as the Letter of Invitation (LOI), and technical problems with the e-visa website. Additionally, special situations like Ramadan may also affect processing times due to reduced staffing.

For many users, it is recommended to apply for the e-visa well in advance of the intended travel date. Notably, some travelers suggest applying no more than three months ahead, considering the visa's three-month validity period from the date of issuance.

According to forum posts, various bus services like Daewoo, Faisal Movers, and Skyways operate between major cities such as Islamabad, Rawalpindi, Peshawar, and Lahore. These buses are noted for being budget-friendly and relatively fast, with approximate travel times ranging from 2 to 5 hours depending on the route.

Some travelers mentioned train services as a viable option for intercity travel. For instance, the Greenline train connects Karachi to Islamabad in about 22 hours. Train services are generally slower than buses but are considered suitable for longer routes.

In local contexts, options such as local passenger hiaces and taxis are frequently used. For instance, from Mingora to Kalam, travelers can take local hiaces. Metro cabs are also available for city-to-city travel, for example, from Islamabad to Mingora.

For more specific routes, services like Shahid Coach offer direct buses from Karachi to Swat, and NATCO/Musherbrum buses operate from Islamabad to Skardu, which are particularly useful for those needing to travel due to canceled flights.

According to forum posts, travelers recommend flying to Gilgit from Islamabad and then driving to Hunza, which takes about 2-3 hours. Public transport is available, but renting a private car can provide more flexibility and comfort for exploring the area.

Some travelers suggested booking accommodations in advance, especially when traveling with family. Popular recommendations include staying in Karimabad in Hunza for its central location to various attractions.

For many users, it's advisable to carry warm clothing as the weather can be unpredictable and cold, especially from March to May when there is still snow. Also, carrying snacks and essential food items is suggested since road delays are common due to the mountainous terrain.

Travelers have called out that mobile signals and internet connectivity are unreliable in Gilgit Baltistan, with Zong/SCOM providing the most consistent service. Despite the connectivity issues, many users have noted that the region is safe for foreign travelers.

According to forum posts, travelers have the option of using both private vehicles and public transportation along the Karakoram Highway. Private vehicles offer the freedom to explore at one’s own pace, which is especially valued for sightseeing and stopping in villages. Public buses are available for travel between major cities like Lahore, Islamabad, and Peshawar, which are connected to the highway.

Some travelers mentioned that renting a private car or jeep is beneficial for exploring the Northern parts like Gilgit and Skardu. The cost of vehicle rental in the North can be around Rs 3000 per day excluding fuel and driver expenses. This option is deemed more economical and flexible compared to organized tours.

Travelers have called out specific scenic spots along the Karakoram Highway for overnight stays or breaks. For instance, places like Besham, Chilas, and the scenic valleys of Kaghan and Babusar are recommended. These spots offer picturesque landscapes and are good bases for further exploration of the surrounding areas.
