Sulphur Channel

The Sulphur Channel is a narrow inshore passage between Green Island and the northwest tip of Hong Kong Island in Hong Kong. The Sulphur Channel is mainly used by small craft and inter-island ferries passing between Victoria Harbour and the East Lamma Channel.
The channel was named after HMS "Sulphur", a bomb vessel commanded by Edward Belcher who took the first British survey to Hong Kong harbour on 25 January 1841. Captain Belcher left HMS "Sulphur" with a landing party on 26 January 1841, disembarked on the northern foreshore, and raised the Union Jack over Hong Kong at Possession Point (what is today Hollywood Road Park). After raising a toast to the Queen with his companions, he officially declared the island the property of Her Majesty Queen Victoria and a Colony of the British Empire.
In the 1990s, the Hong Kong Government had planned to reclaim the channel but withdrew later due to opposition from environmental concern groups.
