One of the must-do's when in Hong Kong is to take a ride on the Star Ferry which has been in existence for about a century.  It is a leisurely 5 minute ride across Victoria Harbour for just HK$2.20.  Locals still use it regularly.  There are three routes: one between Tsimshatsui and Central, another between Tsimshatsui and Wan Chai, and one between Hung Hom and Wan Chai.
