Kau Nga Ling, Mountain chain in Lantau Island, Hong Kong.

Kau Nga Ling is a mountain range on Lantau Island divided into three sections: West, Middle, and East, each featuring sharp jagged ridges. The terrain offers steep scrambles and exposed sections that create a challenging climbing experience throughout the route.

Kau Nga Ling lies within Lantau South Country Park, designated in 1978. Its ridges are formed of volcanic rock, the same material as Lantau Peak and Tai Mo Shan, unlike the granitic mountains of Kowloon such as Lion Rock. The peaks take their name from their dog-tooth profile seen from above.

The name Kau Nga Ling means "Dog Teeth Range", given because the ridges look like a dog's teeth when seen from above. The three ridges are named after their position: West Kau Nga, Middle Kau Nga and East Kau Nga, with the 539 m high point on Middle Kau Nga.

The ridge trails are not maintained by the Agriculture, Fisheries and Conservation Department, and there are no supply points or quick escape routes along the way. Carry enough water and food, especially in summer, and avoid the route before or after heavy rain or when a thunderstorm warning is in force. For a safer view of Kau Nga Ling, walk the Lantau Trail Section 3 up to Lantau Peak.

The Lifeline section between West and Middle Kau Nga features an extremely narrow ridge where only one person can cross at a time. This bottleneck creates a memorable moment that many hikers recall as the route's most distinctive passage.
