To find this cache start by exploring the northerly filming location for ‘Monarch of the Glen’ at Loch Laggan then head down for ‘A Grand Day Out’ and a nice piece of Wensleydale cheese in the Yorkshire Dales before taking a run to search for ‘Harry Potter and the Philosopher’s Stone’ in Alnwick.
The next step of your adventure will take you west to explore ‘Star Wars: The Force Awakens’ near Keswick in the Northern Lakes, before taking a ferry over to Dunoon in Cowal East to find ‘Down Where the Buffalo Go’, then make 'Atonement' for your environmental footprint at Denver, near Downham Market which is south of King’s Lynn.
Rather than exhaust yourself with all that travelling, you may prefer to explore these film locations from the comfort of your armchair before heading to GZ.
