The White River in Northern Ontario is a multi-day wilderness canoe route running approximately 90 kilometres from White Lake Provincial Park southwestward through Pukaskwa National Park to Lake Superior. The route encompasses 18 rapids ranging from Class II to Class VI+, each with a signed and mapped portage trail, giving paddlers the option to walk around any drop they choose. Most paddlers will portage at least half the rapids.

The most significant mandatory portage is a 1.4-mile trail around Umbata Falls, a 100-foot drop that also hosts a hydropower facility. Beginning in 2008, three separate hydroelectric generating stations were installed along the river, permanently altering several formerly celebrated rapids and waterfalls in the upper and middle sections of the route. The portions of the river within Pukaskwa National Park retain their character more fully, including Chigaamiwinigum Falls, which features a 23-metre drop and can be accessed via a 2-kilometre hike to a suspension bridge spanning a 30-metre gorge. Other notable features include Hook Falls, Baptisimon Chute, Angle Falls, and Chicagonce Falls, each with associated portage trails and some with adjacent campsites.

The typical trip from White Lake Provincial Park to Lake Superior takes approximately five days, with paddlers camping on granite ledges beside rapids and in forested canyon settings. Within Pukaskwa National Park, designated backcountry campsites are available, including sites at the White River Portage and White River Interior locations. The White River's outflow into Lake Superior is characterized by strong current, and paddlers should plan for additional days at the river mouth, as wind and surf on Lake Superior can delay safe passage along the shoreline to Hattie Cove.

The river corridor supports abundant wildlife, and the remoteness of the route keeps the surrounding landscape largely undisturbed. Fishing in the White River is noted as productive. Paddlers entering Pukaskwa National Park should be aware that park regulations apply to backcountry travel and camping within that section of the route.
