What to see in Doubtful Sound

With an annual rainfall of 6.8 metres over almost 200 days, the Sounds are one of the wettest inhabited places in the world. Don’t be put off by the thought of a minor downpour though; it’s this water that adds to its unique attraction. A diverse range of fauna is attracted to its lush flora, while deep-sea marine life thrives near its shores. As rainfall drains through the intensely green forest and rushes down countless waterfalls, it becomes stained with tannin. When it meets the saline water from the sea, this tea-coloured water lays on top, blocking out much of the sun’s light. Scuba dive here for a brilliant opportunity to view ancient black coral colonies at just 10 metres beneath the surface. It’s also home to an abundance of crayfish, starfish, sea anemones, fur seals, the Doubtful Sound bottlenoses and some Orca and sperm whales.

The Doubtful part of its name was originally coined in 1770 by Captain Cook, who was unsure about its navigability, though whalers and sealers later changed it from Doubtful Bay to Doubtful Sound. At 421 metres deep, it is the deepest fiord on South Island’s west coast and, some say, the most memorable. Its three branching arms lead to more breathtaking scenery and mountain-backed coves, while its internal archipelago makes for a scenic sail as you soak up the mystery and silent grandeur of this natural phenomenon.
