The land of the midnight sun awaits on the northern shores of Great Slave Lake in Yellowknife, a small but diverse city famous for its spectacular wilderness. Sitting on the edge of the Arctic Circle, the city enjoys summer days with nearly 24 hours of sunlight, and dark winter skies lit up by aurora borealis. Once a gold rush town and now a diamond mining town, Yellowknife is the hub of northern activities, ranging from dog sledding and cross-country skiing to backpacking and birding.

Home to Windsor Castle, the second residence of Queen Elizabeth II, Windsor is a popular day-trip destination from London. Those who tarry in the riverside town fill their time wandering the cobbled streets, popping in and out of the luxe boutiques, restaurants, and tea shops that tumble down toward the Thames River.

Lying at Italy’s geographic and historic heart, Lazio (or Latium) was the seat of the Roman Empire, and as such is teeming with ancient attractions, especially in the Eternal City of Rome itself. To the east, Tivoli has Emperor Hadrian’s exquisite and massive Villa Adriana. Civitavecchia, today a major cruise and ferry port, has been Rome’s main harbor since the second century. Many pre-Roman sites dot Lazio too, like the Etruscan necropolis at Cerveteri, dating from the 9th century BC.

Winter sports enthusiasts will love Berchtesgaden, a village in the German Alps with several ski slopes and a top-notch bobsled track. Visit the Berchtesgaden Salt Mines (TripAdvisor travelers rave about their slides!). Nearby Lake Königsee makes a great day trip.
