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.
A trip to Hunza had always been on my (never ending) wishlist. But honestly I had no idea that it will be this beautiful. It was an achanak trip, with little planning and very little publicity. We didn't invite all our friends for the event, it was just a sudden plan to go on a car and before the rest of our group knew it we were on our way to Gilgit-Baltistan.
