Liu To (Chinese: 寮肚) is the area around the valley in the midwest of Tsing Yi Island. There is a stream in the valley watering the narrow band of agricultural fields of Liu To Village (寮肚村). Its water formerly filled the Tsing Yi Lagoon and nurtured the rice paddies around the lagoon but now is just water flowing in the underground nullah to the Rambler Channel. The valley has occasionally been referred to as the Liu To Valley (寮肚谷) and the surrounding hills as Liu To Hill (寮肚山). The Tsing Yi Nature Trail runs over the hills at the back of the valley.
