The Purple Turnip Festival is a family-fun weekend of free activities in Lisburn Castlereagh, guaranteed to keep the kids amused over the October half-term break.  Enjoy free craft activities and creative workshops. Go on a bug hunt or plant bulbs planting. Taste new, exotic foods or try your hand at creative writing.  And of course, no Purple Festival is complete without the terrific purple turnip hunt, with the chance to win spooky prizes by uncovering cleverly hidden turnips around Lisburn city centre.
