Among the world's most glamorous and cosmopolitan cities, Hong Kong sits on the southern coast of China at the Pearl River estuary of the South China Sea. It comprises Hong Kong Island, where the Central Business District and most affluent areas and attractions are, and, on the mainland, Kowloon and the New Territories. Hong Kong is a regional and global hub for banking, shipping, fashion and food, boasting more than 60 Michelin-starred restaurants. Its five-star hotels are among the most elegant to be found anywhere; many are set in the towering skyscrapers that carpet Hong Kong Island's steep slopes and light up its skyline so beautifully.Officially known as Hong Kong Special Administrative Region of the People's Republic of China, Hong Kong maintains a high degree of autonomy relative to the rest of China, even after it was reunified with China in 1997 after 156 years of British rule ended.Many cruises in Southeast and East Asia start or end in Hong Kong, and it's definitely a great city in which to spend a day or two sightseeing and finding cultural things to do before or after the voyage. Smaller cruise ships can dock right in Victoria Harbour, for front-row seats of the stunning skyline. Unfortunately, pollution is a problem, and sometimes the views are obscured because of it.
