Join the fun and interactive family walking tours and meet Elfish, a grumpy, greedy, little elf who fell from his shelf and is definitely on Santa's naughty list this year.
He needs your help to remember what Christmas is really all about or he will never be allowed back on the shelf again.
Help Elfish search for the answers to some seasonal clues, explore the city centre, and together, you might make sure Elfish is on Santa's nice list before Christmas Eve.
Tours are free and run each weekend from Saturday 1 December to Sunday 23 December. Book your place on the Eventbrite website.
Remember to share your experiences on Facebook, Instagram, Snapchat and Twitter! We'd also love to see your snaps of the festivities too - send them to email@example.com and we'll display the best ones.
