The spectacular Prince Christian Sound provides a protected passage for ships rounding the southern tip of Greenland, at times narrowing to just 1,500 feet across. Waterfalls cascade down the rugged mountain sides, and you can often spot whales and seals amongst the icebergs.

Qaqortoq is southern Greenland’s largest town, though with just 3,000 inhabitants it’s hardly crowded. A trip to the nearby hot springs at Uunartoq is recommended; relaxing in the 38°C water and watching icebergs drift across the bay is quite something.

Greenland’s capital and largest town, Nuuk is positively cosmopolitan compared to the rest of this remote and isolated country. The setting amongst mountains and fjords is striking, and attractions include the Greenland National Museum and the picturesque Old Harbour.

Newfoundland’s capital is a laid back city with an arty vibe, situated on a dramatic harbour. The hilly streets lined with colourful row houses make for a great photo opportunity, and the downtown area is full of history, as well as some excellent pubs and a thriving folk music scene.

The stunning Saguenay fjord is the fourth largest in the world, and the only fjord in North America navigable by cruise ship. The point where the fjord meets the colder waters of the St Lawrence river is rich in krill, which makes this a great destination for whale watching.

Québec City, the capital of French-speaking Canada, is one of the North American continent’s most beguiling cities. The pretty old town, a UNESCO World Heritage Site, is a joy to behold; the cobbled streets and church spires are enclosed within the old city walls, and many of the buildings date back to the 17th century
