Hong Kong offers an infinite variety of things to see and do in a unique fusion of Eastern and Western heritage and culture. Apart from sampling an incredible variety of Chinese cuisine, visitors can find all manner of regional Asian and Western food at reasonable prices. Or take a ferry to the beautiful outlying island of Lamma for some of the best seafood anywhere on earth.
For sightseeing and entertainment, Hong Kong is a city of contrasts – a unique blend of bustling streets and peaceful countryside, of ancient heritage and pristine nature, balanced by modern attractions and theme parks. For active, outdoor types, take your pick from golf to hiking on land, and sailing to powerboating in the beautiful waters that surround the city, or even a unique tram party along the northern shore of Hong Kong Island! All of these activities are easily accessible from anywhere with the compact territory that is made up of almost 70% naturally mountainous countryside.
