Pakistan is not a common destination for a solo female traveler. Visas can be difficult to obtain and most governments have strongly advised against travel there. Visas can only be obtained from the embassy in your country of origin, so if you are planning to travel there first, contact the Embassy of Pakistan in your country.
Before you reach to the destination, you have to face the headache of packing your luggage, making sure all the things are in place, getting on the right transport but they do not always go as expected. Its the test of your psychological strength right at the start of your journey. Like for us, the Journey didn't start as we expected it and we had to face and overcome the unexpected.
