Situated on the western shore of the Lantau Island, Tai O is the last living cultural and natural heritage of Hong Kong. Special architectural features like fishermen's tin houses constructed on stilts scatter alongside waterways named locally as "chung". Tai O was once a prosperous town given its favourable geographical location at the mouth of the Pearl River. Now as both agricultural and fishing activities are in decline, the abandoned salt pan and rice fields are overgrown with mangrove, providing suitable habitat for coastal marine life. Herons and egrets can be sighted from a short distance.
