To get from Hong Kong Island over to Kowloon, I would not normally choose to take the ferry. If I know my way around and if finding parking is not such a hassle, I would drive. If driving is not an option, the fastest way, of course, would be to take the MTR (subway train). If I can get to the place by taking the bus (without having to change midway), that would be my first choice, though. The Star Ferry, for me, is more of a touristy thing to do. That, plus the fact that I don’t particularly like being on the water.
But. I did take the Star Ferry yesterday and I have to say that I enjoyed the ride. What’s more, the fare was only HK$2 (US$0.25)! For anybody coming to visit Hong Kong, taking the Star Ferry across the harbor is definitely a must.
