The Welsh capital may have begun its life as a Roman fort, but it's since become a bustling city. Where the fort once stood, Cardiff Castle has held court since the 11th century. It remains a central presence in the city, now full of lively art and music venues, hip boutiques, fun bars and modern hotels. 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!

Rising up as an indomitable peak at the gateway between Spain and the African coast, Gibraltar is a unique destination with a life that goes beyond its surface. The monolithic Rock of Gibraltar entices tourists with its lush greenery and the friendly Barbary Macaques ubiquitous to the area. Beneath its looming exterior lay the Galleries, a veritable labyrinth of underground passageways running through the Rock. Above ground there is also plentiful tax-free shopping, as well as numerous beaches.

Perfectly positioned at the westernmost tip of sparkling blue Lake Superior, Duluth offers visitors a true escape from the stresses of everyday life and an opportunity to enjoy nature. You can opt for a more leisurely pace: spending time at one of the city's 23 beautiful parks, taking an unhurried drive along the scenic North Shore, bird watching at Hawk Ridge, skipping stones on the Lake with the kids. Or go for a more structured itinerary: the aquarium in the morning, lunch at a sumptuous restaurant on the waterfront plus a tour of the famous Sculpture Walk, then a visit to the historic Railroad Depot in the afternoon. Either way, you are sure to leave Duluth feeling relaxed and refreshed.
