Tai To Yan is a mountain in Hong Kong located within the Lam Chun Country Park in the northern part of the New Territories. Standing at a height of 566 meters at its main peak, it spans across the North District, Tai Po District, and Yuen Long District. Both sides of the ridge are flanked by cliffs or steep slopes, resembling a knife with its blade facing upwards, which gives the mountain its name. There are two major peaks: the northern sub-peak is called “Pak Tai To Yan,” while the southern main peak is officially named “Tai To Yan.” To distinguish between the two, the main peak is often colloquially referred to as Nam Tai To Yan.
