High Island Reservoir, which is Hong Kong’s largest water capacity reservoir, is located in Sai Kung, Hong Kong. It is divided as the main dam and east dam. The nearest coast is Po Pin Chau. In the 70s, the government built the reservoir, during which several rock sections were excavated near the east dam to reveal geological phenomenon including the unique hexagonal basalt columns and the S-curved rock pillar.
Main dam is also known as the west dam. Due to its long distances from the urban area, the light pollution is less severe. The nearby astro-park is suitable for stargazing, enriching your astronomical geography and enjoying the natural wonders.

Attractive View, Enjoyable Play
For those who are interested in geology, have a look at the leaflet that introduces the hexagonal basalt columns or make a visit to High Island. Otherwise, you can visit the Volcano Discovery Centre at the Hong Kong World Geopark near Sai Kung bus terminal. The displayed rock pillar models and specimens are an ideal starting point for your tour.

For hiking enthusiasts, you can go from the East Dam, through Long Ke Wan to the Sai Wan Pavilion, which is a 9km hike that takes around 2 hours. Remember to leave some extra time for nature: you don’t want to miss the beautiful beach of Hong Kong – clear and sandy Long Ke Wan can provide you a chill and relaxing weekend.
