King's Highway 35, also known as Highway 35, is a provincial highway in the Canadian province of Ontario, linking Highway 401 with Peterborough, Kawartha Lakes, and Algonquin Park. The highway travels from west of Newcastle, through Lindsay and the Kawarthas and into Haliburton before terminating at Highway 60 to the west of Algonquin Park. The winding course of the highway, combined with the picturesque views offered along its length, have led some to declare it the most scenic highway in Ontario.
