The Chinese Garden of Serenity is a tranquil haven in which you can contemplate life, the universe and everything as you walk past bubbling fountains and ornate buildings.
Every account of this place features the word 'tranquil' somewhere, so I figured I should go with the crowd in my intro. And generally speaking I would agree with this description, although the presence of a large and boisterous primary school group while we were there detracted somewhat from the spiritual aspects of the garden.
