Plan Your Visit to Doubtful Sound

You do not need a ticket for Doubtful Sound, because there is no gate and no entry fee. If you are weighing up Doubtful Sound ticket prices, what you pay for is the journey in: a boat, a coach over a mountain pass and a cruise, or a flight.

No gate, no entry fee, and no road

Doubtful Sound / Patea runs 40 km from its head to the Tasman Sea. At 421 m it is the deepest of New Zealand's 14 fiords, and it branches into three arms. Early Māori called it Patea, the place of silence.

It lies in Fiordland National Park, which was established in 1952 and has been World Heritage since 1986. The park is part of Te Wāhipounamu, the South West New Zealand World Heritage Area. You can enter it free.

What you cannot do is drive to the fiord. Visit Fiordland puts it plainly: there is no road to Doubtful Sound. So every fare you see here buys the way in, and the few official charges you meet are not for the park.

The journey in, stage by stage

Every day on the fiord follows the same route. You check in at Pearl Harbour in Manapouri, a 20-minute drive from Te Anau. A boat takes you across Lake Manapouri to West Arm, at the far end of the lake.

At West Arm stands the Manapouri Power Station. There are no tours of the station, but you may have time at the information centre. Then a coach climbs over Wilmot Pass, 671 m, and drops through the rainforest to Deep Cove.

Deep Cove has no town, only an outdoor education centre and a few fishing boats. From there your cruise sets out along the fiord towards the sea. The route on a map is on the Doubtful Sound map, and each leg is explained on getting to Doubtful Sound.

Where your day starts

The route is the same for everyone. What changes is where you join it, and that decides how long your day is. Manapouri is the shortest; Queenstown adds about five hours of road.

Your card names your own meeting point, so check it before you set off. In Queenstown, reviewers found two of the operator's buildings close together, so look for the number on Beach Street.

What a day costs

The fares look far apart until you read what each one covers. The cruise from Manapouri is the cheapest way onto the fiord, but you drive yourself to Pearl Harbour. A Te Anau start adds a coach, and a Queenstown start adds a long road day.

Every fare is shown in US dollars, as listed. The levy is in New Zealand dollars, because that is how Immigration New Zealand publishes it.

Weather, and when to go

Doubtful Sound gets around 6 m of rain a year, and Visit Fiordland says there is a good chance it will rain when you visit. The cruises run in all weather. Rain is when the waterfalls pour off every wall, so reviewers who went in the wet often call it the best day.

Winter, from June to August, is the most settled season: often blue and cloudless, with snow to low levels. Spring brings the equinox storms, and summer the long days. Month by month, the detail is on the Doubtful Sound weather page, and the seasons are weighed on the best time to visit.

On the day: what to bring

• A waterproof and warm layers. It is cold on deck when you step outside, even in summer.
• Insect repellent. The sandflies are real, and they find you at every wharf.
• Lunch or a card. The day boats sell food and drink, and they do not take cash.
• Comfortable shoes. You change between boat, coach and boat, over floating wharves.

The cruises are not wheelchair accessible, and you need a reasonable level of mobility for the changes. Dogs are not allowed in the national park, even in a vehicle, and you need a permit to fly a drone.

Refunds, and what the weather cancels

Most day trips and flights refund in full if you cancel at least 24 hours before. The overnight cruise and the 3-day trip from Queenstown are non-refundable and cannot be changed, so be sure of your dates before you book either.

When the operator cancels for weather, you are offered another date or a full refund. The helicopters are the most likely to be called off; landings happen only if the weather allows.

Why every visit here is a tour

At Milford Sound you can drive to the wharf and buy a cruise. Here you cannot. Visit Fiordland says the fiord is only accessible to visitors by a tour excursion departing from Manapouri, and the day trips and overnight trips include your transport by boat and bus.

A private vehicle needs a Wilmot Pass road permit and a barge across the lake, both arranged with DOC. The tawaki, the bottlenose dolphins and the fur seals are all out on the water, which is where the cruise takes you. The fiord's nearer neighbours are set out on things to do around Doubtful Sound.
