Kau Nga Ling (Dog Teeth Range) is located at Lantau Island, the branch range of Lantau Peak, the eastern side of Shek Pik Reservoir. ‘Kau Nga Ling’ literally means the ‘hill of dogs’ teeth’ due to its thin and rugged mountain ridge, such ridge like dogs’ teeth in appearance. There are 3 paths namely West Kau Nga, Mid Kau Nga and East Kau Nga. The most challenging spot is a junction between West Kau Nga and Mid Kau Nga, called ‘a slim chance of survival’. This hiking trail is only suitable for extreme hikers.
