Sai Wan (西灣; lit. "West Bay") is a beach in Sai Kung, Hong Kong. To distinguish it from other bays and beaches of the same name, it is commonly known as Tai Long Sai Wan, as it is one of the four beaches of Tai Long Wan. It came first in the Hong Kong Best 10 Scenic Sites Election in 2006. However, in 2010 the beach is said to be in jeopardy after a nearby plot of greenery was cleared to make way for development.
