There was the chance to meet Santa and Mrs Claus, enjoy some nature crafts, soak up the Christmas atmosphere with music from the Cantabile Choir as well as catch a glimpse of a very curious elf.
Photographer Tony Hendron took these fun-filled photos of some of the many visitors who enjoyed the day.
