The giant Tió pooping log is back again for Christmas at the Santa Llucía Fair in Av. Catedral. He’s so full of food he’s going to be pooping presents for all the children in Barcelona!
This is a free activity. The log will be open from 30 November to 18 December, except on the morning of 14 December, when there are activities programmed for Catalan Christmas Traditions and Customs Day.
