 The highway mostly runs through farmland and small communities , although the route does pass by Earl Rowe Provincial Park and the Honda car manufacturing plant in the Alliston area . Other parks and natural areas that are close to the route are Boyne Valley Provincial Park and Mono Cliffs Provincial Park , both of which are located on the Niagara Escarpment . Further west is the Luther Marsh Conservation Area , a vast wilderness area that surrounds Luther Lake .
