On Hong Kong Island's wild south-eastern tip, Cape D'Aguilar (Hok Tsui) is home to the city's only marine reserve - a 20-hectare stretch of rugged coast prized for snorkelling, sea caves and dramatic rock formations.

An easy paved walk leads past Crab Cave and Thunder Cave to Cape D'Aguilar Lighthouse, Hong Kong's oldest surviving lighthouse (1875) and a declared monument.
