A port city on the southern coast of Wales (and the country's capital), Cardiff delightfully combines old and new.
Located at the heart of the city, Cardiff Castle's Victorian Gothic towers (and stunning interiors) and ancient ruins look like something out of a fairy tale, while the Wales Millennium Centre (home to the opera) on Cardiff Bay is said to resemble a large, mechanical armadillo.
Beyond its eccentric architecture, Cardiff is known for its buzzing waterfront, and the many shops, restaurants, and marina views along Mermaid Quay.
And last but not least, this city also happens to be the hometown of famed children's author Roald Dahl — you can follow in his foot steps on this self-guided walking tour.
