Cruise Mummy Barcelona has a wonderfully festive atmosphere in December. There are Christmas markets selling all kinds of Christmassy things including the 'Caga Tio'. This literally means 'poo log' and it's a traditional Christmas character made from a piece of wood. It's also really cheap to visit Barcelona in the winter and you'll find great deals on flights and hotels outside of the Christmas holidays. Answered by Cruise Mummy
