Best known as the birthplace of St. Francis, Italy's patron saint, Assisi lies amid Umbria's rolling hills. Religious pilgrims have come here for centuries to visit the Basilica of San Francesco (where St. Francis is buried) and the Basilica of Santa Chiara (to see the tomb of St. Clare). Visit the Eremo delle Carceri to see caves where mediaeval hermits withdrew from the world. (You may find such solitude quite appealing—especially if you're here on a daytrip from Rome!)

This Tuscan hill town will transport you back to the Middle Ages. Siena's grand cathedral, built in the 1200s, has treasured artworks and marvellous marble floors. The Piazza del Campo, the main town square, is a UNESCO World Heritage Site. It's also home to the Palio, perhaps the most infamous horserace in the world. No goofy hats and mint juleps here—this is a mediaeval tradition involving bareback riders racing on cobblestones (so as you might imagine, it's quite dangerous). Siena is an easy daytrip by train from Florence, just 43 miles away.

Heaven isn’t too far away from Obergurgl. Maybe because, at 6000 feet elevation, it’s the highest church parish in Austria. Or maybe it’s just the skiing. Take a guided tour with an expert mountaineer, explore the wintery dreamscape off-piste or get exclusive “early bird” slope access that ends with oysters and champagne. Or ditch the skis and go for a winter hike or thrilling toboggan ride. Ski huts and rest stops range from rustic to futuristic, all with panoramic views.

A small fishing village until the 20th century, Gdynia was rapidly built into Poland’s largest and busiest sea port after World War I. As a result, it’s mainly a very modern city. The most significant older attraction is the 13th-century St. Michael the Archangel Church. Two museum ships in the harbor, a destroyer and a frigate, are also popular with visitors. Gdynia has a thriving cultural life and in September hosts the annual Polish Film Festival, sometimes called the “Polish Cannes.”

Sitting on the edge of the Baltic, the modern, cosmopolitan city of Helsinki is the World Design Capital for 2012. The beauty of the surrounding nature blends seamlessly with high-tech achievements and contemporary trends. Walking tours of the city centre show layers of history, while modern architecture and cutting-edge style stake the city's claim to the future. Choose Helsinki during its endless summer days or get adventurous on crisp, snowy winter nights.

Mangroves meet sandy beaches in laid-back Maragogi, a growing town whose locals and visitors both head to the sea for sunset drinks and socializing. The most sought-after treasures are off the coast, where the Gales de Maragogi marine reserve shelters crystal-clear ponds, coral reefs, and colorful fish.
