Manchester is an easy city to negotiate with a substantial public transport system. The Metrolink Rapid Transit system trams are fast and efficient, while the Metroshuttle City Centre buses are free and run on two circular routes, including all major rail stations, bus stops, and Metrolink stops. System One Travelcards offer a variety of options for discounted, unlimited use of public transport.There are plenty of car hire companies and taxis available and the Manchester Airport is only 15 minutes away from the city centre. Manchester also has a system of cycling paths, although these can be a bit risky and intimidating during heavy traffic. Mobile app based taxi services like Uber are also commonly used.
