High Island Geo Trail lies beside the beautiful High Island Reservoir — created after two large dams blocked a narrow channel between High Island and the eastern side of Sai Kung Peninsula. The area, situated within Hong Kong UNESCO Global Geopark, is home to breathtaking rock landscapes of international geological importance formed when a supervolcano erupted 140 million years ago. Signs dotting the leisurely trail offer insights into Instagram-friendly delights including towering cliff faces lined with hexagonal rock columns, mysterious caves and sea stacks and — atop Biu Tsim Kok hill — stunning coastal scenery, such as picturesque Long Ke Wan.
