The Athabasca Landing Trail was a long-distance portage route that linked Fort Edmonton (modern day Edmonton, Alberta) on the North Saskatchewan River with Athabasca Landing (modern day Athabasca, Alberta on the Athabasca River. The distance of the trail between Fort Edmonton and Athabasca Landing was 100 miles giving the trail the nickname "The 100 Mile Portage."
The Saskatchewan flows east and joins the Nelson River which then drains into Hudson Bay. The Athabasca flows north and joins the Slave River, which itself joins the Mackenzie River which drains into the Arctic Ocean. The portage, therefore had local economic significance but was also part of a wider trade network that linked the Arctic and sub-arctic to the rest of North America.
Various portage routes between the two rivers had been used by the indigenous peoples of the region for centuries before the arrival of British and Canadian fur traders in region in the late eighteenth century. Once fur trading posts were established in the region, the same simple trails were also used to move freight between the posts. They linked Edmonton House (in all of its various incarnations of the years), the centre of the Saskatchewan District, to posts in the Athabasca District (including the Peace River Country) such as Dunvegan, Fort St. Mary's, Fort Chipewyan, and Fort Vermilion.
In 1848 the Hudson's Bay Company built a new port at Athabasca Landing in 1848, and that became the main northern terminus of the portage routes.
In 2010, a conceptual master plan for the modern version of the Athabasca Landing Trail was completed. The plan is to build a 150 km non-motorized recreational trail, which runs between Fort Saskatchewan and Athabasca, and highlights the region's historic and natural features. The route is also designated as part of the Trans Canada Trail; it links to the River Valley Alliance Trail in the south and to both the land and water routes north to the Arctic Ocean.
