There are three main types of public transport in Brisbane: buses, trains and ferries (CityCats), all operated by TransLink. Bus routes may be somewhat complicated for visitors, but they do cover most of the city. Buses need to be flagged down and will not automatically stop at bus stops. Two free bus routes that cover a number of popular tourist attractions are available in Brisbane: the City Loop operates around the CBD between red signposted bus stops, using distinctive red buses; and the Spring Hill Loop operates between the CBD and Spring Hill between yellow signposted bus stops, using distinctive yellow buses. Trains are quick and efficient, covering most of the city and suburbs. The ferry system, which serves points along the Brisbane River, is very popular with visitors. Ticketing for all forms of transport is cheap, and works on a zoning system. A variety of passes are available. Cycling is a popular option, and the city has many dedicated cycle-paths. Trains, buses and ferries are equipped to carry bicycles. Taxis can be found in ranks in the city centre and near most major hotels. Taxis may be pre-booked or hailed on the street. Driving a car in the city centre can be confusing because it consists mainly of a grid of one-way streets. There are parkades available downtown.
