U.S. citizens still need to jump through a few hoops to visit Cuba, but as visitors from around the world know, this island offers some amazing opportunities for cultural exchange. Havana is a mix of old-world architecture and of-the-moment culture. Head out of the capital city to the small town of Trinidad to see more Spanish colonial architecture. It’s a UNESCO World Heritage Site and a fantastic home base for a visit to the Valley of the Sugar Mills, a pocket of land that formerly served as the centre of Cuba’s sugar industry.

Welcome to Bluegrass Country, the "Horse Capital of the World". But you don't have to be an avid racehorse fan to enjoy the natural beauty, culture and history that this exciting city has to offer. At the Raven Run Nature Sanctuary, for example, hiking trails wend their way through forests, meadows and gentle creeks, taking you past historic landmarks; there's even a night-time guided walk for admiring the stars. The best place in the world for raising thoroughbred horses, Lexington has over 500 horse farms. The Kentucky Horse Park features films, horse shows and exhibits. Be sure to tour the American Saddle Horse Museum, dedicated to the native Kentucky breed, and watch races at the lovely Keeneland Race Course in season. Historic sites are plentiful here, including the Waveland State Historic Site, the childhood home of Mary Todd Lincoln and the Ashland estate of famed Kentucky statesman Henry Clay.

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.

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.

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.

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.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same.
