Tolo Channel

Tolo Channel or Chek Mun Hoi Hap (Chinese: 赤門海峽) is a channel south of Plover Cove in Hong Kong connecting Tolo Harbour to Mirs Bay. At Mirs Bay end, it is named North Channel.

The Chinese name Chek Mun means Red Gate. Hoi Hap is the modern term for a sea channel. It is named red gate for the distinctive red-coloured sedimentary rocks (rich in iron) to its north.
