The Rivière des Rochers is a significant waterway in northern Alberta, flowing north from Lake Athabasca through the Peace–Athabasca Delta and Wood Buffalo National Park before joining the Peace River to form the Slave River. Its name derives from the French for "River of Rocks." The river is one of the main outflows of Lake Athabasca and winds through a landscape of islands and wetlands within one of the largest freshwater deltas in the world.

The river forms part of a recognized paddling corridor along the Trans Canada Trail, connecting the Athabasca River system to the Slave River. A well-documented route runs from Fort Chipewyan to Fitzgerald (also referred to as the reach to Fort Smith), continuing onward to Great Slave Lake. This makes the Rivière des Rochers a component of longer wilderness canoe expeditions rather than a standalone day-trip destination. Paddlers typically access the route through Fort Chipewyan, with logistical support available at the Parks Canada Visitor Reception Centres in both Fort Chipewyan and Fort Smith, where backcountry camping permits are required and can be obtained.

As with all major river corridors in Wood Buffalo National Park, paddlers should be prepared for natural hazards including high and low water levels, inclement weather, unmarked channels, and submerged rocks. The river is classified as big-river wilderness paddling, suited to experienced backcountry paddlers. Recreational boating is permitted along the river corridor within the park.

The river and its surrounding waters support populations of whitefish, walleye, northern pike, and goldeye, though the water tends to be muddy and silty. The broader delta ecosystem is home to the world's largest herd of free-roaming wood bison, as well as diverse wetland wildlife. The Peace–Athabasca Delta through which the river flows is recognized as one of the largest freshwater deltas globally, lending the paddling experience a remote and ecologically significant character. Canoe rentals are available from the Fort Smith Visitor Centre from mid-May through September.
