Pui O sand

Pui O is a bay formed by the Chimawan Peninsula and the lower slope of Sunset Peak. A major river running eastward from the valley joins other small rivers at Pui O to form a wetland estuary. Villagers have enclosed this wetland and turned it into a paddy field. This is denoted by the name 鹹田 (鹹田; 'Salty paddy field'). At the shore, a sandspit is formed by the interaction of the Southern Ocean currents with the river. The Pui O River is listed as a "Ecologically Important Streams" by the AFCD. However, the river has been polluted by illegal dumping activities recently.
