Lahore is a huge and sprawling city. In the old town walking or a tuk-tuk are your only options. You get to see a lot more on foot, just remember to wear comfortable shoes if you are going to be walking a great distance. Outside of winter it will be too hot to walk long distances during the day. Sunday mornings are quiet and are a good time to explore.
Beware about asking address from people in Lahore. You will often be misguided and will end-up going somewhere else. Ask two or three people to confirm the address. Using the GPS function on your phone can be helpful.
Walking Due to the traffic, distances, extreme heat, and hordes of goggling locals, however, most tourists will prefer to use other means of transport.
Auto-rickshaws / tuk-tuks or 'Qingqi'pronounced chingchi are open rickshaws with narrow rear-facing seats, or with two seats facing forward and two backward. They are handy for moving around in the Inner City, since it's easier to see where you're going. Tourists used to average western road etiquette might be horrified by the chaos on the roads - but it almost seems to work. Qingqi drivers have an unbelievable sense of space, speed and angles and you may well learn to trust them or not. Rickshaws are the cheapest and, for women, the safest individual forms of public transport. Haggle thoroughly with the driver; if you do not speak Punjabi or Urdu or are clearly a foreigner, try to get a Lahori friend to ensure you don't get ripped off. Try to find a rickshaw with a well-padded seat, otherwise you will come out bruised and aching.
Taxis are a rarity on the streets of Lahore - with auto-rickshaws having cornered the market - for a taxi you need to book one by phone. Most taxi drivers and, indeed, rickshaw drivers, carry mobile phones; it may be useful to take a number down if you find someone especially reliable. Do not take taxis in the Inner City, as the streets are narrow and very crowded. Either walk or take a qingqi.
Minivans are probably the most dangerous form of public transport, with very rash drivers. Women will find these especially uncomfortable, as they are very crowded. Often women must sit in an undersized cubicle or with the driver, to prevent harassment.
Buses are usually cleaner and more comfortable than minivans, and usually a have a separate seating area for women. Saami Daewoo bus service is an airconditioned bus service operates for different parts of the city.
From the airport - When you arrive at the airport you will likely be besieged with touts offering you taxis and rooms. It's wise not to book anything through them and arrange a taxi yourself to the hotel of your choice. Some of the mid-range and most top-end hotels offer a courtesy shuttle from the airport. If you do use an airport taxi then be firm, agree a price which includes the Rs50 to leave the airport carpark and pay in advance. Should be around Rs600 to Gulberg, Rs1,000 to the old town.
