Sailing Milford, Doubtful and Dusky Sounds - a morning of some of Earth's most dramatic scenery viewed from the ship's decks, with no landing. What to expect, the three sounds, the wildlife, and why weather can change the plan.
In Fiordland scenic cruising, an ocean cruise ship enters one or more of the fiords, slows to a near-drift and turns within the sound so passengers can take in the sheer cliffs and waterfalls from the open decks. Unlike a shore excursion, nobody disembarks; the visit is a sea day spent watching the landscape slide past. Milford Sound / Piopiotahi is usually the first fiord of the day, timed for early morning, sometimes followed by Doubtful Sound and, on longer itineraries, remote Dusky Sound.
Milford Sound / Piopiotahi is the most famous, running 16 kilometres to the Tasman Sea beneath the iconic 1,692-metre Mitre Peak and lined with cliffs that stream with waterfalls after rain. Doubtful Sound / Patea is far larger and quieter, a three-armed fiord known to Maori as Patea, the place of silence, and rich in wildlife. Dusky Sound / Tamatea is the most remote and historically significant, the largest fiord and the place where Captain James Cook and his crew spent five weeks in 1773.
The fiords lie within Fiordland National Park, established in 1952 and now covering over 1.2 million hectares, part of the wider Te Wahipounamu / South West New Zealand World Heritage Area inscribed by UNESCO. Several of the sounds also contain marine reserves, including the Piopiotahi (Milford Sound) Marine Reserve. This protected status means vessels operate under conservation rules designed to safeguard the fragile marine and forest environment - some of the least modified land remaining in New Zealand.
Cruisers commonly spot New Zealand fur seals (kekeno) hauled out on rocks, resident pods of bottlenose dolphins, and the rare Fiordland crested penguin (tawaki), which breeds on islands in Dusky and Doubtful Sounds. Milford Sound receives around 6.5 to 7 metres of rain a year, among the highest of any inhabited place on Earth, and this rainfall unleashes hundreds of temporary waterfalls, though only Lady Bowen and Stirling Falls flow year-round. The main season runs November to April, and a rainy day paradoxically delivers the most dramatic scenery.
Fiordland scenic cruising is highly weather-dependent, and fog, low cloud or heavy swell at the fiord entrances can force a ship to alter its route or skip a sound entirely. Lines that commonly include Fiordland on Australia and New Zealand itineraries include Princess, Celebrity, Holland America and Cunard, featuring it as scenic cruising rather than a port of call. Because Milford is usually entered soon after dawn, early risers are rewarded; the best vantage points are the forward observation decks, the bow and any balcony as the ship turns. Dress warmly, as open decks are cool and often wet even in summer.
