The road can be found south of Blenheim and starts in the Awatere Valley, it offers access into the Marlborough high country through Molesworth Station to Hanmer Springs from the end of December to Easter each year. This is a remote and ruggard route so make sure you have a full tank of petrol and a spare tyre, drive carefully on the winding shingle road and watch out for oncoming traffic. Rental cars can not be taken over this route. The scenery is spectacular and there is a lot of NZ farming history associated with this area.
