This summer, escape the heat for a day at Wookey Hole, where there are more events running than ever before. A whole new underground world is waiting to be explored, where never-before-seen caves have been blasted and uncovered. Get to grips with their history; learn how they were formed and who lived in them. Special events that are new for summer 2017 include the Superhero Circus Show; a daily showcase of young performers who will unicycle and skate their way round the theatre and dazzle you with juggling, hula hooping, trapeze tricks and magical illusions. Also new for this season is the 4D cinema experience showing ‘Happy Family’, an adventure-filled show promises surprises and thrills. Join Harold – bat companion to the Witch of Wookey Hole – in the middle of an experiment that has gone horribly wrong. Can you help?
