Leung Shuen Wan (High Island) Leung Shuen Wan (High Island) is an island and former island-peninsula in the Sai Kung District of the New Territories, Hong Kong. It forms a prominent feature within the Sai Kung Peninsula seascape and is adjacent to the Sai Kung East Country Park, Tung Ping Chau maritime region, and the mouth of the Tolo Harbour system. The area is notable for its volcanic columnar joints, maritime access from Port Shelter, and role in regional conservation policies administered by the Agriculture, Fisheries and Conservation Department.

Introduction

Leung Shuen Wan (High Island) lies off the southeastern coast of the New Territories and has been integral to the coastal geography of the Sai Kung District and the marine landscape of Hong Kong. The site is widely studied in connection with the Cretaceous volcanic province of the South China Block, discussed in literature alongside formations such as Sharp Island and Po Pin Chau. It sits within proximate governance zones associated with the Hong Kong Observatory and maritime jurisdiction of the Marine Department, making it relevant to navigation, conservation, and regional tourism initiatives promoted by the Hong Kong Tourism Board.

Geography and Geology

The island is part of the volcanic terrain created during the Cretaceous period within the Mesozoic tectonic settings of the Pearl River Delta. Its shoreline features extensive columnar jointing in rhyolitic tuff and lava, comparable to formations at Fisherman's Island and High Island Reservoir East Dam exposures used in geological fieldwork by institutions such as the University of Hong Kong and the Chinese University of Hong Kong. Leung Shuen Wan is situated near navigational passages used by vessels transiting Port Shelter, Junk Bay approaches, and channels serving Sai Kung Town. The island's topography includes cliffs, wave-cut platforms, and intertidal zones that link to broader sedimentary processes observed in the South China Sea littoral.

History

Human interaction with Leung Shuen Wan spans traditional fishing, fortification, and modern engineering. Local fisherfolk from nearby villages in the Sai Kung Peninsula and the indigenous communities of the New Territories utilized the waters for standardized practices recorded in surveys by the Hong Kong Museum of History and ethnographic studies from the Education University of Hong Kong. During colonial-era charting by the Hydrographic Department and surveying by the Royal Navy, the island featured in navigational charts and surveys that informed construction of infrastructure such as the High Island Reservoir project undertaken in the 1970s by civil engineers associated with the Public Works Department. The reservoir scheme altered hydrology and access, linking the island to mainland via dams designed with consultation from firms and agencies including the Geotechnical Engineering Office.

Ecology and Environment

The island and adjacent waters host habitats for species documented by the Hong Kong Bird Watching Society, the Kadoorie Farm and Botanic Garden, and marine surveys conducted by the Swire Institute of Marine Science. Avifauna recorded include migratory and resident species tracked through projects by the Wildlife Conservation Society and local NGOs active with the Agriculture, Fisheries and Conservation Department. Coastal marine assemblages comprise coral communities comparable to those studied around Hap Mun Bay and Sharp Island, with population assessments referenced in reports by the University of Hong Kong's Swire Institute. Terrestrial vegetation on exposed rhyolitic substrates shows assemblages similar to those in the Sai Kung East Country Park and conservation areas overseen by the Leisure and Cultural Services Department.

Human Use and Infrastructure

Leung Shuen Wan has been used for recreational boating, diving, and educational fieldwork supported by organizations such as the Hong Kong Underwater Federation, the Hong Kong Maritime Museum, and academic programs at the City University of Hong Kong. Infrastructure impacts include the High Island Reservoir dams, roads and trails connecting to the East Dam, and moorings serving tour operators regulated by the Transport Department. Cultural heritage in the surrounding area ties to temple sites and village settlements on the Sai Kung Peninsula and features in cultural mapping by the Antiquities and Monuments Office.

Conservation and Management

Conservation measures affecting Leung Shuen Wan are implemented within frameworks administered by the Agriculture, Fisheries and Conservation Department and informed by legislation such as ordinances managed by the Environmental Protection Department. The site's geological value led to its inclusion in geopark initiatives linked to the Global Geoparks Network and the regional Hong Kong UNESCO Global Geopark program, which coordinates with stakeholders including the Hong Kong Geopark management and academic partners from the Geological Society of China. Ongoing management addresses marine protected area planning undertaken in consultation with NGOs like the Hong Kong Marine Conservation Society and research institutes such as the Swire Institute of Marine Science to balance tourism, heritage interpretation by the Hong Kong Tourism Board, and habitat conservation.
