The town walls of Conwy are part of the fortification of the town that includes the castle. They cover 1,400 yards in an almost unbroken circuit around the town. And the almost unbroken circuit is an important distinction because more than once I saw guidebooks/tour guides suggesting that you can walk around the town walls the same way as you can at York and no, you definitely can’t. In fact I found some extra COVID restrictions had been left in place with some of the walls closed off completely and others with instructions that the route was one way only – at some places that was completely impractical and if you’d followed the signs your only option would have been to jump up into the sea!
