Rawalpindi is a large sprawling city - however the centre, focused on Raja Bazaar is walkable - but easy to get lost, so a GPS or compass isn't a bad idea. To get from one part of town to another eg Raja Bazaar to Saddar its best to hop in a tuk-tuk. Buses are an option for going up or down Murree Road, but working out how to get a bus to more far flung parts will require some Urdu. A trip to Bahria Town is best done in your own car or a taxi and armed with a map.
