With one of the best public transport systems in the world and a compact city centre, getting around Hong Kong is easy enough for even inexperienced travellers. The underground Mass Transit Railway (MTR) is efficient and inexpensive. Double-decker and single-decker buses cover all of Hong Kong Island, Kowloon and the New Territories with final destinations displayed in both English and Chinese. Bus fares are low and distance-based; exact change is required. Small mini-buses are more expensive but also more flexible, stopping for passengers to board or disembark on request. Hong Kong's old-fashioned trams are also a cheap and convenient way of getting around. On the water, fleets of ferries connect Hong Kong Island, Kowloon, and the Outlying Islands. Last but not least there is an abundant supply of taxis, colour-coded according to their area of operation. Taxi fares are low, but many drivers don't speak English and visitors are advised to have their destination written down in Chinese characters.
