As York is highly pedestrianised, the best way to take in all the sights and sounds of the city is on foot. Many travellers also choose to hire a car, and there are plenty of major car rental agencies around, but taxis, buses and trains are all reliable and readily available. Parking tends to be expensive, and the streets can be confusing for new arrivals. There are about 20 bus routes, and the city is separated into zones, with the cost of the journey varying accordingly. Off-peak day passes are available. Hiring a bicycle is also a good option for exploring the city, as it is accommodating towards cyclists.
