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.

With its hilltop castle and medieval architecture, Guimaraes looks like it's straight out of a fairy tale. Said to be Portugal's birthplace, the city boasts UNESCO status and houses manicured gardens, a historic palace, and a 13th-century church.

A self-guided walking tour is the best way to appreciate the stunning architecture of Viana do Castelo. The buildings date from several different centuries so styles vary: highlights include the early 20th-century Basilica of Santa Luzia; the 16th-century fountain and former city hall building at the Praça da República; the gothic Cathedral on the Largo da Matriz; and the Monument to Caramuru and Paraguaçu, built just a few years ago in 2009.

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi. La Sagrada Familia, considered Gaudi's masterpiece, is still under construction (your entrance fee helps to fund the project). Feel like a picnic? Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.

Amsterdam is truly a biker’s city, although pedaling along the labyrinthine streets can get a little chaotic. Stick to walking and you won’t be disappointed. The gentle canals make a perfect backdrop for exploring the Jordaan and Rembrandtplein square. Pop into the Red Light District if you must—if only so you can say you’ve been there. The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

Looking out over the city of St. John's, you may be reminded of a mini San Francisco (minus the cable cars). St. John's provides the ideal balance between nature and nightlife, from the East Coast Trail and its stunning scenery to the colourful entertainment district along George Street. Although it's the largest city in Newfoundland, the vibe is still very small-town. You'll feel welcome in the City of Legends!

Montreal, c’est si bon! This French-speaking city is considered the cultural capital of Canada, and is a cosmopolitan celebration of Québécois style. A horse-drawn carriage ride around the cobblestone streets and grand buildings of Vieux-Montréal will give you a taste of European flavour. The Basilique Notre-Dame is a confection of stained glass, and the Plateau Mont-Royal district will delight you with its quaint boutiques and cafés. Dig in to a massive plate of poutine to fuel up for a tour of the epic Olympic Park.

Ottawa is a compact, clean, cleverly planned centre of culture and politics. And it's an ideal choice for a weekend getaway. Start downtown at the architecturally stunning National Gallery of Canada, and don't miss the Canadian Nature Museum and the National Aviation Museum. Rideau Canal offers boating in the summer and ice-skating in the winter. Gatineau Park attracts cyclists and walkers, while Byward Market blends old and new Ottawa.

The first time you go to New York, go ahead and be a sight-seer—everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighbourhood and go deep. You’ll find hole-in-the-wall bars, great delis, quirky shops… exploring the non-touristy side of New York is an incredibly rewarding experience for a traveller.

We've heard Toronto described as "New York City run by the Swiss," and it's true—you can find world-class theatre, shopping and restaurants here, but the sidewalks are clean and the people are friendly. The best place to start is literally at the top—the CN Tower, the tallest freestanding structure in the Western Hemisphere.

Toronto's neighbour Mississauga has more than 480 parks and woodlands for you to explore. Stroll the Waterfront Trail, rent a boat at the marina or spend a day at the racetrack. It's also called Ontario's shopping capital, with everything from shopping centres and outlet malls to picturesque village-style shopping streets.

As North America’s northernmost large metropolis, Edmonton is a fascinating study in contrasts — a vibrant urban centre in the heart of the wilderness. It’s a city that’s never been afraid to do things a little differently, as visitors discover through close encounters with free-roaming bison, a shopping mall that spans more than 48 city blocks, and a dynamic arts and culture scene that embraces more than 40 annual festivals, including the continent’s biggest and wildest Fringe Theatre Festival.
