Your mission (should you choose to accept it!) is to complete tricky tasks and decipher the most cryptic of questions as you make your way around the city centre.
This has to be one of the most fun ways to explore this awesome Spanish city as you get to know the hotspots whilst completing challenges and taking in some of the iconic sights over the course of two and half hours.
Don’t worry if you’re not that academic, this is about thinking outside the box and working as a team so it’s fun and accessible for everyone.
Just get stuck in and do your best. Complete all the tasks to complete your super special mission. How do you think your group would do?
