By Air
Pakistan's main international gateway is Islamabad International Airport (ISB), which handles most long-haul traffic. Jinnah International Airport in Karachi and Allama Iqbal International Airport in Lahore also receive international flights. Smaller airports at Peshawar, Multan, Faisalabad, and Sialkot have limited international services.
Pakistan International Airlines (PIA) operates routes to the Middle East, Europe, and beyond, though its reputation for delays is well-earned. Emirates, Turkish Airlines, Air Arabia, Qatar Airways, and Etihad all fly into Pakistan with connections from most major cities worldwide. From within Asia, options are plentiful and often reasonably priced.
By Land
Overland entry is possible but limited. The Wagah border crossing between Lahore and Amritsar (India) is the main land crossing with India, used by tourists and operates for pedestrians and vehicles with certain restrictions — check the current status before planning on it, as it closes periodically due to political tensions.
From China, the Khunjerab Pass on the Karakoram Highway is officially open to foreign tourists from May to October, depending on conditions. Entry from Iran is possible through Taftan in Balochistan, but road conditions and security along this route are challenging. Overland entry from Afghanistan is not recommended.
Visas
Most nationalities require a visa. Pakistan offers an e-visa for citizens of around 120 countries, typically issued within 24–48 hours for tourism purposes. Apply online before departure. Your passport must be valid for at least six months beyond your arrival date.
Note: anyone departing Pakistan must show proof of a polio vaccination received within the past year. Carry documentation of this if you've been vaccinated.
