PR 307 begins at Provincial Trunk Highway 11 (PTH 11) and heads east approximately 12 kilometres (7.5 mi), passing through the community of Seven Sister Falls, before entering Whiteshell Provincial Park. It then winds through the west-central region of the park before ending at PTH 44 near Rennie.[1][2]
Provincial Road 309 (PR 309) is a 12.2-kilometre-long (7.6 mi) east-west spur of PR 307, located entirely within Whiteshell Provincial Park. It provides access to several trails and picnic areas of the park, as well as Big Whiteshell Lake and Big Whiteshell Lake Lodge at its eastern end. It is entirely a paved two-lane highway, paralleling the course of the Whiteshell River for the majority of its length.[4][5]
