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.

Tallinn's atmospheric Old Town is an enthralling hotchpotch of medieval streets and spires. It's a small city, and the tourist areas are safe and easily explored on foot. Buy a Tallinn Card if you intend to use buses, trolleybuses or trams. For a look into Tallinn's past, visit Rocca-al-Mare Open Air Museum's typical rural Estonian taverns, windmills and watermills, see the onion-domed 1900 cathedral or join the bustle in historic Town Hall Square. St Olav's spire was once the tallest in the world.

Plan to cross many bridges when in Cork. Ireland's third-largest city began life as an island and now spans both banks of the River Lee, with watery channels running beneath some of its main thoroughfares. The best way to experience this hilly southern seaport is on foot, following the signposted walking tour past St. Finn Barre's Cathedral and the riverside quadrangle of University College up the hill to red and white Shandon Church. Along the way, you'll meet plenty of the city's talkative residents.

travellers generally come to Bilbao to see the Guggenheim—some for the art inside, but many for the amazing building itself. The Fine Arts Museum and the Basque Museum may not have been designed by Frank Gehry, but are worth a visit, and you can catch international opera stars at the Palacio Euskalduna.

With its prime vantage point atop multi-hued cliffs in Portugal's southern Algarve region, it's easy to imagine Albufeira's eighth- century Arab occupants calling the city "Castle of the Sea." Brightly painted fishing boats, stunningly white houses with Moorish flair and remnants of its old fortress provide echoes of earlier days, while lively nightlife accentuates its modern resort charms. Spend time sunbathing on the more than 20 diverse beaches that hug the coast or venture inland, where almond trees blossom and local handicrafts are abundant.
