The Wales Coast Path's website has information on movies that have been filmed there, as well as where to go if you want to walk where the stars did.
Even if you have no interest in recreating a scene from your favorite movie, the Wales Coast Path still has plenty to offer. Wildlife Trust Reserves dot the trails, as well as castles, Roman forts and more. Walking plans are customizable for seeing what you want to see, whether it's wildlife, the best beaches or the most charming towns to stop in along the way. You can also take a short, half-day walk or plan something longer.
