International air service is excellent and fares are relatively cheap. Visitors should reconfirm onward or return tickets well before departure or seats may be lost. An express train to Beijing takes about 30 hours. Several transport companies in Hong Kong offer bus services to Guangzhou, Shenzhen and several other destinations in Guangdong Province. There are also boats that take you to destinations in Guangdong and Guangxi Provinces.
Public transport is cheap, fast, widely used and generally efficient.
The bus system is extensive and bewildering but you will need it to explore the south side of Hong Kong Island and the New Territories. Three tunnels link Hong Kong with Kowloon. Double-decker trams trundle along the northern side of Hong Kong Island. Hong Kong's ferries are usually faster and cheaper than buses and trams. They are also fun, and the harbour views are stunning when the weather cooperates.
