Leeds has a good bus system that serves the city and much of West Yorkshire. Day passes are good value for travellers, and can be bought on the bus. The Leeds CityBus loops around the city centre, passing every six to seven minutes. It is a slow, but scenic way to get around the city and see the sights, operating on a hop-on, hop-off capacity for £1 a ride. For visitors staying in the city centre, the easiest way to get around Leeds is on foot. Central Leeds is mostly pedestrianised, making car travel impractical. Taxis are available, with pre-booked taxis generally cheaper than the black and white cabs that can be hailed on the street. Uber and other taxi apps are also available.
