10-Day Canada & New England Circle: New France & Montreal

Reykjavik, the world's northernmost capital, distils the entire improbable beauty of Iceland into one compact, creatively charged city. The soaring basalt columns of Hallgrímskirkja dominate a skyline of primary-coloured rooftops, while the Harpa Concert Hall shimmers beside the harbour like a captured aurora. Day trips from the city unlock the Golden Circle's geysers and Geysir hot spring, the black sand beaches of Vík, and the ethereal glacier lagoon at Jökulsárlón. Geothermal pools — from the legendary Blue Lagoon to intimate neighbourhood hot pots — offer warmth year-round. June and July bring the bewitching midnight sun.

Heimaey is Iceland's volcanic island where the dramatic 1973 eruption story, the world's largest puffin colony of one million breeding pairs, and the children's annual puffling rescue create one of the North Atlantic's most extraordinary port experiences. Visit May through August via Lindblad or Windstar for Eldfell volcano hikes, the Eldheimar Museum's excavated homes, and the harbor approach through a channel literally reshaped by eruption.

The Saguenay is a glacially carved fjord of Norwegian grandeur hidden in Quebec, where three-hundred-meter cliffs plunge into waters hosting the world's southernmost beluga whales alongside blue whales, fins, and humpbacks. Visit September through October via Cunard or Azamara for autumn-color fjord transits, world-class whale-watching at Tadoussac, and one of Canada's most spectacular and least-expected natural treasures.

Qaqortoq is southern Greenland's largest town, where brightly painted houses climb above a fjord harbour amid open-air stone sculptures and Norse ruins. Must-do experiences include visiting the Hvalsey Norse church ruins, soaking in the Uunartoq hot springs surrounded by icebergs, and tasting Arctic char and musk ox. June through September offers the accessible season, with July and August warmest for fjord exploration.

Qassiarsuk (Brattahlíð) in southern Greenland is where Erik the Red founded the first European settlement in the Americas in 985 AD — today a tiny sheep-farming village preserving Norse ruins, a reconstructed Viking church, and a graveyard of 144 colonists. Must-dos include walking the archaeological remains with a local guide, visiting Hans Lynge's bronze Erik the Red, and absorbing the fjord-and-ice-cap setting. June through September provides snow-free access and wildflower-dotted ruins.

Nanortalik, Greenland's southernmost town, sits amid fjords of staggering granite walls and drifting icebergs at the edge of the inhabitable Arctic. Must-dos include boat excursions to Tasermiut Fjord's 1,500-meter granite spires, visiting the open-air museum of Inuit heritage, and tasting traditional Greenlandic cuisine. July through September offers the only navigable window for visiting.

Saint Pierre and Miquelon is France's last territory in North America, a fog-wrapped archipelago off Newfoundland where croissants, crêpes, and the euro coexist with cod fishing and Prohibition-era history. Must-dos include exploring the rum-running Heritage Museum, dining on fresh cod and French wines, and visiting the haunting cemetery on Île aux Marins. June through September offers the best weather for this improbable outpost of French culture.

Prince Christian Sound is Greenland's most dramatic navigable passage — a forty-kilometer corridor between thousand-meter cliffs and hanging glaciers that expedition ships from Seabourn to Silversea transit when ice conditions permit. Navigate July through September for humpback whale encounters, iceberg-studded waters, and the visceral Arctic experience that empties every cabin and fills every open deck regardless of weather.

Skjoldungen, Greenland is a distinctive port city where deep cultural heritage meets authentic local atmosphere, featured on itineraries by Ponant. Must-do experiences include exploring the historic quarter to absorb centuries of architectural heritage, and sampling the distinctive northern cuisine that transforms local ingredients into refined dining experiences. The optimal time to visit is June through August, when summer months bring the warmest temperatures and longest days.

Tasiilaq is the largest settlement in East Greenland with just 2,000 residents, one of the most remote inhabited communities on Earth, surrounded by the spectacular Sermilik Icefjord, massive glaciers, and tundra that blooms intensely during the brief Arctic summer. Must-dos include a boat trip through the iceberg-filled Sermilik Icefjord, hiking the Valley of Flowers, and watching traditional tupilak carving and drum dancing. Visit August for the warmest weather and best icefjord access.
