Dusky Sound

Dusky Sound is a fiord on the south west corner of New Zealand, in Fiordland National Park.One of the most complex of the many fjords on this coast, it is also one of the largest, 40 kilometres in length and eight kilometres wide at its widest point. To the north of its mouth is the large Resolution Island, whose Five Fingers Peninsula shelters the mouth of the sound from the northwest; along the east coast of the island, Acheron passage connects Dusky Sound with Breaksea Sound, to the north.

The sound has been identified as an Important Bird Area by BirdLife International because it is a breeding site for Fiordland Penguins.Access to the sound is by sea or air only, with no roads reaching the coast at this point. However, the Dusky Track stretches to the upper reaches of the sound from lakes Manapouri and Hauroko.
