Cardiff is the capital city of Wales and a vibrant port destination full of important historical sites and charming Victorian arcades. Cardiff cruises dock in Cardiff Bay, along a stunning waterfront, and from there passengers are ferried off via bus. (Smaller ships sometimes dock at Britannia Quay.)
Cruisers might want to tour Cardiff Castle, a famous medieval castle in the city center. St. Fagans National Museum of History, located just outside of Cardiff, features manicured castle grounds and interactive exhibits -- well worth the trip.
