Old Dunstan Road, also known as The Dunstan Trail, is a 4x4 track located in the Otago Region in the South Island of New Zealand.
The road ranges from a sealed road to a graveled track. It’s 98.2 km long. Closed for about four months each winter, the Old Dunstan Road is best traversed with a 4 wheel drive vehicle. It can be done on a rainy day too but the road will change into a single mud track. The road was part of the original route called the Mountain Road taken by hardy people seeking their goldrush fortunes in the early 1860s. The road is sealed at the start and turns to gravel after 9.2km. It then varies between gravel, clay and bare rock. It is rutted in places, slippery when wet, dusty when dry and can be closed in winter by snow and ice. There is no shelter from the weather, which can change quickly, and it is bitterly cold in a southerly. Because of the fragile environment, vehicles and mountain bikes must keep to the track.
The road is closed from the first Tuesday in June to 30th of September.
