Halloween at Caerphilly Castle
Nine days of Halloween activity at one of Britain's biggest castles, built around a children's quest with a prize at the end. Medieval medicine demonstrations and crafts fill the first weekend, with bubbles and face painting over Halloween itself. Much of it is outdoors in the castle grounds and no advance booking is needed, though normal admission applies.
📅 24 Oct – 1 Nov
📍 Caerphilly Castle, Castle Street, Caerphilly
