Rearguard Falls Provincial Park, Provincial park with waterfall in Fraser-Fort George, Canada

Rearguard Falls Provincial Park covers 49 hectares on the south side of Highway 16, about 5 km east of Tete Jaune Cache. The Fraser River runs east to west through the park and drops about 6 metres over a width of 18 metres at the falls. The park is an IUCN category III natural monument next to Mount Robson Provincial Park.

Rearguard Falls Provincial Park is a 49-hectare protected area in the Fraser-Fort George Regional District, set beside Mount Robson Provincial Park on the Fraser River just above its entry into the Rocky Mountain Trench. The sources record no founding date, so the 1991 date and the fishing history in earlier texts are unsupported. The park is classed as an IUCN category III natural monument, a designation given to protect the 18-metre-wide, roughly 6-metre drop of the falls.

The falls sit just above where the Fraser River enters the Rocky Mountain Trench, near Tête Jaune Cache, and the park borders Mount Robson Provincial Park. The name Rearguard refers to the falls' position at the rear of the salmon run: Chinook salmon reach this point at the end of their upstream migration and spawn below the drop.

Visitors reach several viewing platforms through a network of maintained trails starting from a parking area along Highway 16. The trails are straightforward to navigate, and informational signs help visitors find the best vantage points.

The falls mark one of only two locations along the entire Fraser River where Chinook salmon must cross a natural barrier during their upstream journey. This rare spot offers visitors a chance to observe the strenuous effort of these fish as they navigate their migration.
