Shek Pik (Chinese: ) is an area located along the southwestern coast of Lantau Island, Hong Kong. When the Shek Pik Reservoir was built, villages at Shek Pik were demolished and the villagers were relocated to other parts of Lantau Island and to Tsuen Wan. Below the dam of the reservoir is Shek Pik Prison.
Shek Pik was originally a north-south oriented valley, until all the upper part was filled by the water of the Shek Pik Reservoir, which was completed in 1963. Before the construction of the reservoir, the valley was settled by several villages and most of the valley floor and the foothills were occupied by terraced paddy fields. The southern part of Shek Pik is facing the South China Sea and features three small bays. From West to East: Tai Long Wan (), Chung Hau () and Tung Wan (; 'eastern bay').
A tradition mentions that a clan from Ma Tau Wai in Kowloon accompanied the last two young emperors to Lautau Island and finally settled in Shek Pik to avoid the Mongol invasion at the end of Southern Song (1127-1279). Based on the review of historic documents, the existence of village settlements at Shek Pik can be traced back to the Ming Dynasty (1368-1644), although the area may have been settled earlier. The villages were largely self-sufficient farming and coastal fishing communities. The main village, Shek Pik Wai (; 'the walled village of Shek Pik'), was located near the head of the main valley. A populous place in the mid-19th century, its population had declined to 363 inhabitants by the time of the 1911 Hong Kong Colony census, and numbered 202 in 1957. Fan Pui Village () had 59 inhabitants at each count.
The villages of Shek Pik Valley - Shek Pik, Fan Pui, Kong Pui () and the hamlet of Hang Tsai () - were demolished and cleared to allow construction of the Shek Pik Reservoir. A total of about 260 people were resettled as a consequence. Most of the villagers of Shek Pik Village moved into five-storey apartment blocks in the urban Shek Pik New Village (?) in Tsuen Wan. Most of the villagers of Fan Pui moved to a new village nearby, Tai Long Wan Tsuen (?) at Tai Long Wan, Shek Pik. Some families from both villages moved to a row of houses near Mui Wo Ferry Pier.
The villagers of Fan Pui had chosen to move to the nearby new rural village of Tai Long Wan Tsuen in order to continue farming. Remodeling long abandoned fields allowed to provide them with about the same acreage of rice fields near the new village. Tai Long Wan had a population of about 120 people in 1970. By 1983, with the younger villagers moving to the city, the population had declined to 22 and most of the farming activity had ceased.
Rock carvings from the neolithic age were found by Chen Kung-chiek in Shek Pik in 1939 when the local villagers told him there was an engraved carving on the upper part of the beach and to the west of Tung Wan. There was the second carving found on the opposite side of the valley. It has been split into two parts by lightning and the rock is now lying face down so the carving can not be seen.
According to the local villagers, there is the third carving further up the valley. This carving, (later called "the upper Shek Pik Rock Carving" to distinguish it from the one found on the Shek Pik Beach) was found on a steep slope in Shek Pik in 1962. The carving is at 350 m (1,148 ft) above sea level.
A Hau Wong Temple used to be the focal point of the village life at Shek Pik. It was inundated by the Shek Pik Reservoir in 1960. A Hung Shing Temple was located at Chung Hau. It was ruined as in 1979. A new temple was built in 1960 at Tai Long Wan.
Two institutions operated by the Correctional Services Department are located at Chung Hau and Shek Pik: the Sha Tsui Detention Centre and the Shek Pik Prison. Sha Tsui Detention Centre is a minimum security institution for male young offenders. It was established in 1972. Shek Pik Prison is a maximum security institution, housing male adults serving medium to long-term sentences, including life imprisonment. It was established in 1984.
Shek Pik is located at the end of Stage 8 and at the beginning of Stage 9 of the Lantau Trail.
