309 Road is a 22-kilometre (14 mi) long gravel road between the towns of Coromandel and Whitianga in New Zealand. It winds its way from Coromandel, on the west side of the Coromandel Peninsula, over the ranges to Whitianga, on the eastern side. The road is considered extremely dangerous and deaths among tourists unfamiliar with the road and in unfit vehicles are common. Places of interest along the road include Waiau Falls and the Kauri Grove, a stand of mature kauri trees.
