Although I haven't done it on a bike yet, we used to drive this route in our cages because it was twisty heaven combined with phenomenal high-country panorama. From Heyfield it takes about 40 minutes to get to Licola if you move it. After Licola it turns to dirt. It runs through large green valleys and follows a mountain river most of the way up. There are also some great old wooden bridges for some outstanding photo opportunities. The road up to Walhalla is similar although less time is spent running along the side of panoramic valleys. Walhalla is absolutely worth the trip. As is continuing a bit further north to see the enormous dam.
