With its iconic skyline, thriving food scene and clockwork-like efficiency, Hong Kong is truly one of the world's great cities. It's a contradiction of sorts, housing both the densely populated CBD and pristine mountainous nature reserves; entertaining visitors with everything from beautifully traditional Cantonese Opera to baijiu-fueled karaoke; and offering avid shoppers the choice of the world's most exclusive luxury brands or mass-produced market goods that can be purchased with loose change. It's these sorts of contradictions that make Hong Kong a wonderful place to visit and a perfect city to explore.
