Doubtful Sound

Cascada Bay in outer Doubtful Sound
Some of the clearest waters

Doubtful Sound is part of Fiordland National Park in South Island and while it may not be as popular as the nearby Milford Sound, the fiord is popular for its remoteness. The best way to experience and explore the fiord and its solitude is by kayak.

The official name of the fiord is Doubtful Sound / Patea, with Patea being the Maori name.





Doubtful Sound got its name from James Cook, who was too doubtful to sail the fiord at the time. Because of the huge amounts of precipitation, the fiord is covered with a layer of freshwater several metres thick.



Flora and fauna


What you definitely have to deal with are hordes of sandflies. These little beasts can truly drive you insane if you let them. There are good insect repellents that reliably protect against the pests.
