The 309 Road
An extremely winding, curvy road which local tourism sites say "takes you on a journey through dense bushland with lots of surprise stops to make along the road".
According to Wikipedia, it either got its name from there being 309 bends in the road, or because horse-drawn coaches used to take 309 minutes to travel it.
The road was reportedly developed the Gold Rush era.
A Coromandel travel blog called it "a largely unpeopled landscape, bordered by river, backdropped with birdsong".
On TripAdvisor, one dissatisfied traveller wrote, "Avoid that road.. Just too dangerous, that road can turn your beautiful holiday to a terrible memory."
Another described it as a "drive through Jurassic Park", saying they "loved the pure adventure of this secluded drive through exotic tropical rainforest which I never knew existed".
Among the attractions described on the road was a honey shop and an ancient kauri grove, places for swimming an picnicking, as well as Waiau Falls and the scenic Castle Rock.
The Waiau Waterworks park featured a display of water sculptures, while a large wild pig farm was another well-known stop.
