While many visitors come for the beaches, arts celebrations and fiestas, San Sebastian-Donostia is serious about its food and drink. The Old Quarter’s narrow, winding streets are full of bars and restaurants, and in the modern city, sidewalk cafes are all around. The city specialises in seafood. Just make sure you know not to expect dinner at 6 or 7 p.m.—that’s much too early in Spain. Instead, tide yourself over with tapas, and enjoy eating and drinking late into the night.

A stylish beach town on France’s southwestern coast, Biarritz was once the holiday spot for nobility and is now Europe’s surfing capital. It’s experienced a tourist renaissance—summers are busy. Biarritz lacks the Riviera’s glitz, but you’ll see affluent holiday-makers in designer gear and surfers in flip-flops, and hear French, Spanish and Basque. The Grande Plage is the centre of the action. Behind it, visit the restored, Art Deco casino and wander the streets down to the old port to the west.

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.

Situated at the foot of the western Pyrenees near the French border, Spain's Basque country comprises three provinces: Guipúzcoa and the popular beachfront capital of San Sebastian; Viscaya, where capital Bilbao houses the jaw-dropping Gehry-designed Guggenheim Museum; and Alava, whose capital Vitoria teems with medieval architecture. Running with the bulls at Pamplona and drinking rioja from local wineries add to the region's exotic romanticism. Travel in early summer and autumn to avoid the crowds.

Aix, a graceful, lively city, is known for its thermal hot springs, art schools and universities. Wander the Cours, old town and Quartier Mazarin on foot, stopping at cafés, bookstores and markets. Kids whining? Have them count fountains… Aix reportedly has 1,000 of them.

The town that gave the country (and port wine) its very name, Porto is Portugal’s second-largest metropolis after Lisbon. Sometimes called Oporto, it's an age-old city that has one foot firmly in the industrial present. The old town, centered at Ribeira, was built on the hills overlooking the Douro River, and today is a UNESCO World Heritage Site. The 14th-century São Francisco church is a main attraction, as are the local port wine cellars, mostly located across the river at Vila Nova de Gaia.

Land of Mermaids. Land of Orange and Lemon Groves. Land of Colors. This small city in Campania has earned a plethora of alluring names. Famed for its sea cliffs, the town's steep slopes look out over azure waters to Ischia, Capri and the Bay of Naples. The birthplace of Limoncello liqueur offers some good diving, great sea fishing, boat cruises and appetizing restaurants. Excellent hiking trails cross the peninsula. Rent a car or take a taxi if the steep streets look too intimidating.

From the heights of the Bay of Fundy tides to the sandy beaches and warm waters of the Acadian coast, New Brunswick is home to spectacular natural wonders and first-class attractions. The Canadian province is also renowned for its outdoor adventures, natural and recreational parks, pristine rivers, lively cities, picturesque towns and vibrant culture. Add a dash of Acadian joie de vivre and its people’s legendary friendliness and you have the makings of a truly unique Maritime experience.

Known for its markets and its striking 19th-century limestone architecture, Kingston is a great base for exploring the Thousand Islands and the St. Lawrence River and its national park. Visit Wolfe Island on the free ferry, or hunt for antiques in nearby villages.

East meets West in this sun-soaked state, where Indian culture intertwines with Portuguese influences left over from a 500-year occupation. The beaches have long served as a magnet for serene hedonists. To the north, the tourist-centric scene is prevalent, with an international flair that is now skewing more hip than hippie. Travel south for stretches of unspoiled sand and an escape from large resorts. Temples, mosques and wildlife sanctuaries provide diversions from the beach.
