Tai Mo Shan, Mountain summit in New Territories, Hong Kong.

Tai Mo Shan is Hong Kong's highest peak, rising to 957 metres at the centre of the New Territories. Its upper slopes are bare pale grey-brown rock and sparse grass, while dense dark green vegetation covers the lower flanks. A narrow winding trail follows a ridge crest toward the summit, and deep gullies divide the green slopes below. The actual summit is occupied by a weather radar station and is closed to visitors.

Tai Mo Shan is an extinct Jurassic volcano of coarse ash crystal tuff, later intruded by granodiorite formed about 150 million years ago. In Ming and Qing times the whole range was called Kwun Fu Mountain, after the salt field Kwun Fu Cheung in today's Kowloon Bay. Tai Mo Shan Country Park was formally designated on 23 February 1979.

The mountain was traditionally an area where villagers grew a special variety of green tea, which benefited from the frequent mist and high humidity found on its slopes.

The summit itself is closed: above 930 metres lies within an Observatory restricted zone, and the weather radar station occupies the top. Walkers can drive or hike the Tai Mo Shan Forest Road to the gate just before the restricted area, which already exceeds 930 metres but is not the mountain's highest accessible point. Fog is heaviest in March and April, and winter ice and frost make the road slippery.

During winter months, frost forms at the summit area while the rest of Hong Kong maintains its subtropical climate. This unusual weather pattern makes the mountain one of the few places in Hong Kong where visitors can experience cold conditions firsthand.
