One of the things recommended to me to try when I made it to Hong Kong, was the ferry. This was actually one of the cheapest, more enjoyable things I did there. It was something like 2.5 Hong Kong dollars to take it from one side of the water, to the other.
There was too much smog for my liking, it kind of ruined the view of Hong Kong in general.
Lots of passing boats.
The destination terminal, a nice brief ten minute ride away.
The ferry from the destination terminal departing before ours arrived.
Much more enjoyable than the subway - and cheaper!
