Indulgence is easy at the stunning ESPA at Powerscourt Hotel.  Elegant and sleek interiors are highlighted by the central Swarovski crystal-lit pool and emphasised further by 20 treatment rooms, including a private spa suite.  The dramatic, contemporary design complements the beauty of the nature it overlooks, with stone, wood and slate elements and its position in the Wicklow countryside means it also benefits from views of the Sugar Loaf.  Impeccably beautiful, a true five star spa.
