This is a flight through history.
Departing from the town of Norman Wells, your flightseeing tour will take you twisting through the Mackenzie Mountains, tracing the Canol Trail – a ghostly military-supply route carved through impossible country during the frenzy of World War Two.
You'll witness the mouldering evidence of this monumental endeavour – airstrips, barracks, old army trucks, and remnants of the road-bed.
Plus, you'll see famous Dodo Canyon, proud Carcajou Falls, and wild critters (like grizzlies, caribou, moose and mountain sheep) that have never laid eyes on a human being.
The East Arm of Great Slave may be the most scenic swath of lakeshore in Canada.
Taking off from Yellowknife, you'll soar over this glittering expanse of trout-filled bays, cliff-flanked channels, and red-rock island.
Below you'll see sailboats leaning against the breeze, fishing lodges busy with anglers, and historic outposts from the North's explorer-past.
Muskoxen are often spotted here, and moose and bears, too.
And pure glory: a paradise, in blue, green and gold. It's the prettiest sight you'll ever see, from the perfect vantage point, a thousand feet high and floating.
Here it is: the biggest protected area in North America, rolling out before you like a canvas of grandeur.
Wood Buffalo has just a handful of roads, meaning most of this Switzerland-sized park can only be experienced from the air.
You'll also see the park's namesakes: the biggest herd of wild bison left in North America, browsing the boreal plains and kicking up dust.
To look down upon them is to peer backwards in time, into a pure and primordial age. Drink it in.
Just upstream from Inuvik, Canada's greatest river splits into a million tendrils and the whole world turns into water.
Your pilot will guide you out over the Mackenzie Delta, weaving above its maze of channels and pointing out the birds and beasts that thrive in the liquid below.
Farther along, there's the Arctic Ocean, often sheathed in ice, sometimes splashing with whales, and always wrapped in mystery as it stretches toward the pole.
Also here: pingos! Those famous, ice-filled hills, erupting from the tundra in Parks Canada's Pingo Canadian Landmark.
And finally, plucky Tuktoyaktuk, our hub of Inuvialuit culture, perched precariously on the polar shore, proud of its title as the Northwest Territories' largest outpost north of the treeline.
Nahanni is the granddaddy of all flightseeing destinations. When your plane rises from Fort Simpson, the famous features will soon leap into view.
Your pilot will call out their names: the Headless Range. Deadmen Valley. Hell's Gate. Sunblood Peak, Lotus Flower Tower and the Cirque of the Unclimables. Little Doctor Lake. Scimitar Canyon. The Moose Ponds and Rabbitkettle Mound.
And of course the centrepiece of it all, Virginia Falls, 30 stories high and roaring beneath your wingtip, too mighty to be believed.
It's a tour every Canadian should take at least once – a pilgrimage, almost. For everyone else, it will merely be the trip of a lifetime.
