Tenby is lovingly protected from the outside world by an embrace of 13th-century stone walls, which, ironically, attract—not repel—visitors from all over the world. The town is simply adorable, teeming with the archetypes of pubs and shops one would expect to find in a U.K. city. Adding further appeal are the miles of gorgeous beaches and the gently lapping waves of a blue-grey sea.

Even with so many new and exciting things to see, the National History Museum is still the most visited attraction in Wales. Don't be the only visitor who plays hooky!
