💧【Reservoirs】 are not only Hong Kong’s water supply facilities, but also multi-faceted resources that seamlessly combine natural landscapes, historical engineering, and hiking recreation. They are distributed across the New Territories, Kowloon, Hong Kong Island, and Lantau Island. Hong Kong’s reservoirs showcase a perfect “blend of engineering wisdom, natural beauty, and cultural history”. Ranging from the century-old heritage of the Kowloon Group of Reservoirs to the world-class geological wonder of High Island Reservoir, and further to the “Thousand Islands Lake of Hong Kong” at Tai Lam Chung Reservoir, they serve not only as the city’s lifelines for water supply, but also as precious destinations for hiking, photography, and cultural exploration.
