Cape Breton's Cabot Trail (Nova Scotia): This 280km (174-mile) loop through the uplands of Cape Breton Highlands National Park is a world-class excursion. You'll see Acadian fishing ports, pristine valleys, and some of the most picturesque coastline anywhere.
Viking Trail (Newfoundland): Travelers looking to leave the crowds behind needn't look any further. This beautiful drive to Newfoundland's northern tip is wild and solitary, with views of curious geology and a wind-raked coast. And you'll end up at one of the world's great historic sites -- L'Anse aux Meadows.
Icefields Parkway (Highway 93 through Banff and Jasper national parks, Alberta): This is one of the world's grandest mountain drives. Cruising along it is like a trip back to the ice ages. The parkway climbs past glacier-notched peaks to the Columbia Icefields, a sprawling cap of snow, ice, and glacier at the very crest of the Rockies.
Highway 99 (British Columbia): The Sea to Sky Highway from Vancouver to Lillooet takes you from a dramatic seacoast past glaciers, pine forests, and a waterfall that cascades from a mountaintop and through Whistler's majestic glacial mountains. The next leg of the 4-hour drive winds up a series of switchbacks to the thickly forested Cayoosh Creek valley and on to the craggy mountains surrounding the Fraser River gold-rush town of Lillooet.
Dempster Highway (from Dawson City to Inuvik, Northwest Territories): Canada's most northerly highway, the Dempster is a year-round gravel road across the top of the world. From Dawson City, the road winds over the Continental Divide three times, crosses the Arctic Circle, and fords the Peel and Mackenzie rivers by ferry before reaching Inuvik, a Native community on the mighty Mackenzie River delta.
