Getting around in Calgary is easy as most of the city's attractions are concentrated within the city centre. The streets downtown are laid out in a numbered grid with avenues running east to west and streets running north to south, while in outlying areas neighbourhoods have more meandering streets which can be confusing to visitors.Because of the grid system, walking around downtown Calgary is a simple way to get around. The Eau Claire market area and the Stephen Avenue Mall are pleasant pedestrian-only areas. Calgary's public transport system is efficient and reliable, with a light rail and bus system servicing the city centre. The light rail runs from 4am to midnight every day, and the buses operate from 5am to midnight, with some routes continuing until 1am. There is a fare-free zone in the middle of town, and in other areas a pass can be purchased at many convenience stores.There are plenty of taxis available, either by hailing them in the street or calling the dispatch. Note that taxis cruise mainly the central areas of the city. Driving in Calgary is relatively stress-free. Many streets are one-way, and streets marked 'transit only' are for public transport vehicles only.Parking downtown can be scarce and confusing, as the city uses an automated pay system that requires you to enter your zone and license plate number into a pay station. It is often easier to park in a private lot. There are numerous companies from which you can hire a car in Calgary.
