Canada’s longest river, reaching 1,738 kilometres, the Mackenzie drains one-fifth of Canada but retains the mystique of a remote frontier waterway. Often called Deh Cho (big river), it was for centuries the North’s superhighway, linking the many peoples who fished, hunted and trapped along its banks. Today, paddling the Mackenzie is still the best way to experience the heart of the Northwest Territories. Paddlers not only have a chance to visit the dozen or so traditional communities that flank it (from Fort Providence at the headwaters to Tuktoyaktuk near the mouth), but also see mountains, hotsprings, and the awesome Ramparts – limestone cliffs that pinch the river near Fort Good Hope.
