Promenade at Tsim Sha Tsui
From the Star Ferry Pier through to the eastern part of Tsim Sha Tsui East there is a continuous waterfront pedestrian path known as the Promenade. It's a great walk with fabulous views, and different stretches have various interesting things to see. Most well know is the section called Avenue of the Stars which has tributes to Hong Kong stars such as Jackie Chan and Bruce Lee.
It is by far the best place to watch the Symphony of Light daily light show.
