On the Caernarfon Spy Mission Treasure Trail a deadly device is ticking and you’re the ones to deactivate it… Are you up to it?

If you have any hope of cracking this case you’ll need the best tools in the business; that means downloading your trail PDF. It’s packed with  hints leading you to clues all over town - remember though that these will be hidden on landmarks so will take every ounce of super spy intuition to spot!

The dastardly villain has allotted 1.5 hours before the device detonates. If you can find the deactivation code in that time you’re then free to explore the sights and take a well earned break! The local castle would be a great spot for a picnic as the kids explore the grounds, while the harbour has plenty to see, smell and explore.
