Welcome to Doubtful Sound
Until relatively recently, Doubtful Sound was isolated from all but intrepid explorers. Even Captain Cook only observed it from off the coast in 1770, because he was ‘doubtful’ whether winds would be sufficient to blow the ship back to sea. Access improved when the road over Wilmot Pass opened in 1959 to facilitate construction of West Arm power station.
Boat and coach transfers from Manapouri to Deep Cove are easily organised through tour operators, but time-consuming enough to deter some travellers...ideal for those who want to enjoy the silence.
