The fares within the City boundary are based on the number of zones through which you travel, and the diagram above shows the zone areas. The zone colours are repeated on bus stop signs throughout the City and the zone boundaries are also detailed in our timetable leaflets.
If you stay in the same zone you pay a one zone fare, cross into a second zone and you pay a two zone fare, and so on. Please note, however that there are some variations to this arrangement where certain services run parallel to the zone boundaries, such as the City Circle services.
