How to get from happy valley to central hongkong?

Hi, Shaun. Do you refer to the Tsim Sha Tsui in the downtown area by "central HK" ? If yes, you may take bus line 1, and get off at Pacific Place Station. Afterwards, transfer to the MTR Tsuen Wan Line at the Admiralty Station, and get off at the Tsim Sha Tsui Station.

If you refer to the Central Station of MTR Island Line or Tsuen Wan Line, you may take a tram at the Happy Valley Terminus, and get off at the Des Voeux Road Central (Pedder Street).
