A striking landscape of ancient, glacially-carved valleys, Doubtful Sound Patea is a panorama of awe. Discover a natural landscape that is both precious and powerful.

One of the finest examples of a fiord environment

Doubtful Sound Patea spans a staggering 40 kilometres (25 miles) from the head of the fiord to the Tasman Sea. It is the deepest of New Zealand’s 14 fiords and its immense size leaves all who visit feeling humbled yet uplifted by its powerful physical presence.

The fiord branches into three arms which provide opportunity for scenic cruise boat passengers to explore up-close sheer cliff faces, impressive waterfalls and tranquil overnight moorings. Doubtful Sound Patea also provides shelter to New Zealand’s southernmost population of bottlenose dolphins and tawaki, the Fiordland Crested Penguin.

Spend just a short amount of time immersed in Doubtful Sound Patea and it is easy to understand why early Māori named the fiord, Patea-meaning ‘place of silence’. Here, visitors find silence amongst a dramatic landscape with echoing birdsong or cascading waterfalls the only sound to break the stillness.

With no road to the fiord, the experience of getting to Doubtful Sound Patea is an adventure in itself.  Doubtful Sound Patea is only accessible to visitors by a tour excursion departing from Manapouri.

Doubtful Sound Patea's English name transpired when Captain James Cook approached the entrance of the fiord during his voyage of 1770. The vast fiord was only just visible from the sea and Cook decided if they ventured into the fiord it would be “doubtful” they would be able to sail back out against the prevailing westerly wind. He named it 'Doubtful Harbour' and carried on up the coast. The area was renamed Doubtful Sound  many years later by whalers and sealers. Today, visitors to the fiord bear witness to scenery mostly unchanged since the time of early Māori and Cook’s cautious exploration. Doubtful Sound Patea has kept its stunning beauty well hidden and shares it with those who truly seek a wilderness experience.
