Normally in other cities of Pakistan, there are other modes of public transportation too, like Chingqui and Rickshaws etc. But in Gilgit-Baltistan, there are no such kinds of vehicles and Taxis are commonly used here. It is used for intra-city transport but you can hire a taxi for inter-city transport as well if you are moving from one city to another, like from Skardu to Gilgit or Gilgit to Hunza etc. In short, hiring a Taxi is a useful decision if you are visiting nearby tourist destinations like you can visit Shigar Fort, Manthokha Waterfall from Skardu by hiring a Taxi. But for longer destinations like Deosai or remote areas of Shigar and Roundu it is better to hire a Jeep or any other kind of vehicle, Taxis wouldn't be a good choice for those dilapidated roads.
Taxis are plentiful, clean, safe, and inexpensive in Gilgit-Baltistan. They can be found at taxi stands, airports, in markets and in front of hotels etc. The fare of the Taxis is not fixed, it changes from time to time and region to region. Note this in mind and make sure to have some cash ( in PKR) because there is no any system of credit cards or pre-paid public transportation cards system.
