For me, one of the hidden gems of Hong Kong is the trams, and if you have the time (the trams are not fast) and you want a genuinely novel Hong Kong experience, then take a tram.
I was down at Chai Wan in Hong Kong and needed to return to Wan Chai. I could have taken the Metro (MTR) from Chai Wan to Wan Chai, and the trip would have taken 20 to 30 minutes; however, as I had some spare time, I decided to take the MTR to Shau Kei Wan and then board a tram at Kam Wa Street (///ideals.astounded.crest). The trip took around 50 minutes and cost HKD 2.30 (£0.25; $0.45 USD).
When you catch a tram from Kam Wa Street, you must be careful as picking a tram to the wrong final destination is easy. The trams go to the Happy Valley or on the western market routes. I needed the western market.
