I’d long heard the South Island travellers’ hot tip: Doubtful Sound is THE place to go if you ever make it to Fiordland National Park. Lauded as the most beautiful, extraordinary experience many have had in New Zealand, the expectations were sky-high.
At 421m deep and 40km long, Doubtful is the deepest and second longest fiord in South Island. This means there are many magical corners to explore! And gosh, did my experience exploring them only exceed my expectations?
Read on to discover exactly what made my Doubtful Sound Overnight Cruise experience so enchanting and unforgettable.
Where does the Doubtful Sound overnight cruise depart from?
The Doubtful Sound cruise departs from Lake Manapouri.
How to get to Lake Manapouri:
You will need to make your own way to Manapouri. Most visitors do this by self-driving.
However, if you’re not renting a car in New Zealand, then the best option is to get a coach ticket. Real Journeys (who run the cruise) also run several shuttle services – you will need to book this in advance to make sure you arrive on time. Some shuttle services from Queenstown go directly to Te Anau. If necessary, you can take a taxi from here to Manapouri, as they’re fairly close.
Alternatively, make things easier and book a tour that includes transport from Queenstown, such as this Doubtful Sound day trip from Queenstown, or this 3 day Doubtful Sound adventure from Queenstown.
It’s also possible to take a scenic flight from Queenstown.
Your tour will begin from the RealNZ visitor centre at Lake Manapouri. From here, you’ll take a cruise across Lake Manapouri, followed by a magical bus ride to West Arm where you’ll board the ship.
Which Doubtful Sound cruise should you pick?
There are three main options for the Doubtful Sound cruise, all of which are run by expert tour operator RealNZ (previously named Real Journeys). If you’re wondering what the best Doubtful Sound overnight cruise is for your needs, this is my advice:
- One-day Doubtful Sound cruise: This option is best if you only have time for a day trip. However, if you only have one day, you might also consider doing to Milford Sound cruise instead. Milford Sound is smaller, so you won’t feel like you’re missing out on anything by exploring it one day. (Of course, you could also do one of each… but in that case, I’d recommend doing two days in Doubtful Sound, below, to make the most of your time.)

- Doubtful Sound Overnight Cruise (one night, two days): If your South Island itinerary allows for two days in Doubtful Sound, I highly recommend it. Since Doubtful covers such a large area, in one day, you simply won’t have time to discover how huge and breathtaking the fiord is. Staying on the boat overnight and being able to watch the sunset over the water is an unforgettable experience.

- Two days, three nights (WINTER ONLY): in this tour option, you’ll have a whole day on the water without having to travel by land to get there and back. This is undoubtedly the best way to immerse yourself in the beauty of Fiordland.
See prices or book tickets: check the RealNZ website for more details.
If you have the time and budget for an overnight option, I highly recommend it. If I had to pick the single best and most memorable thing I did in New Zealand, then this would be it!

SUMMARY: the basics – what to expect on your Doubtful Sound Cruise
Read my full overnight cruise review below, but here’s an overview of what you can expect to see and do on the cruise.
Exploring the ship: get behind the captain’s wheel, watch the anchor go down at night, and climb the ladders and staircases to get different perspectives of the magical Doubtful Sound. You can also curl up in your private or shared cosy cabin each night.
Wildlife: Alongside an abundance of native birds, including albatrosses and the elusive Fiordland Crested Penguin, you might also see bottlenose dolphins, whales, fur seals and whales. While fur seals are a common sight, you’ll have to get lucky to see the whales and penguins!
There’s a wildlife guide on board with you the whole time, so don’t worry about missing out on anything as they’ll keep their eyes peeled for you. (Read more about the wildlife I saw during my trip in the detailed review section below!)
Food and drink: Food comes as buffet options at breakfast, lunch, and dinner. Dietary requirements are catered for (phew, as I’m a vegan traveller!) but make sure you let the crew know in advance. Tea, coffee, juices, and water are covered, but you can also purchase additional drinks from the bar.
Activities: I go into more details about onboard activities below, but one of the best is the opportunity to kayak on the sound!

MY DOUBTFUL SOUND OVERNIGHT CRUISE EXPERIENCE + personal review
My memories of Doubtful Sound remain very special to me, so below are my personal experiences. Read on to find out what the overnight cruise is really like, and things you can expect to see on the way.
If you want general travel tips, rather than my personal Doubtful Sound review, then skip to the end of this article and check the FAQ below.
THE JOURNEY TO DOUBTFUL SOUND FROM TE ANAU
Reaching Doubtful Sound is a journey in itself.
The tour began at the RealNZ office at Lake Manapouri. As I boarded our first ferry on Manapouri Lake, I was excited, and from the offset, things were off to a promising start. This first hour-long cruise glided through breathtaking Fiordland mountain scenery towards our connection at West Arm.
After arriving on the other side of Manapouri Lake, we boarded a 45-minute bus journey that manoeuvred around the twisty mountain road that formed the Wilmot Pass. This 671m high pass was completed to assist the construction of the Manapouri Hydroelectricity Project, connecting the power station at Lake Manapouri’s West Arm to boats offloading equipment at Doubtful Sound’s Deep Cove.
After passing waterfalls, rivers, and scenic viewpoints, we arrived at Deep Cove, where the Fiordland Navigator was waiting for us.
There was a hum of anticipation as we boarded the ship. And, following a brief introduction on how to safely make the most of our adventure, we were given the keys to our cabins and time to investigate our home for the next two nights.
I wasn’t aware before boarding that the RealNZ Doubtful Sound cruise takes a different route every time. Depending on weather conditions and potential wildlife sightings, the ship will take the smoothest yet most exciting route possible. This means every trip is unique!
Waking up in a different part of the Sound each morning is a treat. During my trip, we began the second day at Crooked Arm and the third at Bradshaw Sound. Each spot has unique views, all seemingly more spectacular than the last.
OUR SHIP – THE FIORDLAND NAVIGATOR
Fiordland Navigator is a purpose-built ship ideal for Doubtful’s distinct balance of soothing exploration. While the exterior and dining saloon possess the allure of a bygone era, this charm matches perfectly with cosy cabins and comfortable inside and outdoor observation decks.
But the best part of the ship was the crew – from the hardworking chef to the friendly staff, you always felt in great hands.
Even the bridge was accessible, meaning you could chat with the skipper as he drove the ship. This, along with the commentary from the onboard nature guide, means visitors are always invited to learn more about the area and feel involved. Even the youngest kids on board got a chance to drive!
We also got to watch the crew raise the anchor. But don’t worry if you miss it; you’ll definitely hear it! Fortunately, the crew calls out all events, so you can unwind in the warmth, knowing you won’t miss anything.
On a side note, dietary requirements were accounted for throughout the day, from breakfast options to numerous choices at the 3 -course buffet dinner – including vegan and gluten-free alternatives. This was a relief, as I know from experience how hit and miss it can be travelling with a dietary requirement!
Visitors could freely wander the ship, building our day with spectacular views from every corner of the vessel. With spacious outdoor or indoor viewing decks, I never felt crowded trying to see the views. This only added to the peaceful and secluded setting. With no other boats on the water, it felt like a very rare opportunity to gaze upon an otherwise untouched land…
THE WILDLIFE OF DOUBTFUL SOUND
If you’re a wildlife lover or birding enthusiast, you will be spoilt on your Doubtful Sound cruise. Many seabirds and marine life are home here, although no specific individual animal spotting is guaranteed. This makes sense for a company committed to conservation – this is generally the sign of an ethical animal encounter. When animals are wild and free, they appear as and when they wish. (For me, this is essential to truly enjoy a wildlife experience, so I really valued this.)
Among the common sightings are fur seals and albatross, and I loved seeing the fur seals relaxing on the rocks.
I was also lucky enough to see bottlenose dolphins swimming in the Sound! Seeing them swimming and breaching alongside small waterfalls and crooked trees was amazing. Best of all, it began to snow. Imagine that – watching dolphins jump through a flurry of falling snow!
Unfortunately, I didn’t see any Fiordland penguins during my trip, though I wasn’t disappointed since they are one of the world’s rarest penguin species. On occasion, whales are spotted as you sail into the Tasman Sea!
At this point, I must shout out Div, our onboard wildlife expert. His passion and fascination with the wild was contagious, and despite his keen interest, he remained very accessible and perceptive. Respected by children and adults alike, both long-term nature lovers and the vaguely curious were able to gain something from his commentary and willingness to answer questions.
ACTIVITIES DURING THE DOUBTFUL SOUND OVERNIGHT CRUISE
While impossible to get bored of the everchanging scenery, there are also various ways to thoughtfully plan activities throughout the cruise. Participation is not mandatory, but everyone was keen to join in during my trip!
The second day’s kayak and tender boat adventure was the most notable activity. Whether paddling your kayak or relaxing in a tender boat, there’s no better way to get up close and personal with flora and fauna. Doubtful Sound looks immense from afar, but when you get close, you notice all the distinctive plants, rocks, and trees growing in the valley. The birch trees, who were the inspiration behind Lord of the Ring’s Treebeard, looked particularly characterful when dressed in a fresh suit of snow.
After climbing back aboard the Navigator, those brave enough took the ‘Polar Plunge’ and jumped back in the Sound’s cold water from the deck!
On board, there are various board games and books to enjoy, though my favourite discovery was the piano! The guests still lingering in the dining saloon post-breakfast were courteous enough to not only accept my request to play the piano but to politely applaud after. I very seldom get the chance to play music, and having the opportunity to unexpectedly practice in such a welcoming, unique environment (on board a literal ship in the wilderness!) remains a very special memory.
For a restful after-dinner activity, I headed to the viewing area for a nature talk by Div (our resident nature guide). This was a fab way to get the lowdown on this wild region of New Zealand. From clips of previous animal encounters and fascinating facts to learn about conservation efforts and what we can do to help, the talks were the perfect way to conclude each day.
THE MANY MOODS OF DOUBTFUL SOUND
I soon came to realise that climbing aboard the Fiordland Navigator was a gateway to more than just one mysterious fiord. In fact, cruising Doubtful Sound is like setting sail upon the waters of a thousand worlds at once.
The changing weather conditions mean one hundred different experiences of one location – or ‘the Many Moods of Doubtful Sound, as Div fondly called it. There is no ‘wrong way’ to see Fiordland, with the landscape transforming anew with each day or hour.
Famously stunning in rainfall, some say ‘you haven’t seen the Sounds before you’ve seen it in the rain’! Stormy weather brings the landscape to life, creating hundreds of waterfalls in just a few hours. Only a few of the falls are permanent, such as the aforementioned Brown Falls.
That said, stormy weather will make you reluctant to voyage into the Tasman Sea, where you feel the waves at their most choppy.
During my trip on fortunately calm seas, Div pointed out the Hares’ Ears – two rocks reaching 18m out of the water. Div told us he’d seen waves crashing the entire way over the formation, rendering them barely visible! Usually a calm, slow trip, the Tasman Sea is the only time you’re warned to sit down or hold onto the railings.
During my visit, our lucky conditions led to a vibrant double rainbow majestically arching over the entrance of the Doubtful Sound as we returned from the sea – a very inviting return!
The staff were also excited by the double rainbow on the first evening – just as they were by the serene, reflective sunset on the second. It reminded me, once again, that every trip to Doubtful Sound is unique, and there are always more natural treasures to be found in the skies above to the waters below.
The reflective scenery on our final night was otherworldly, with snow hanging low on the mountains and a calm sky painting the water with its changing colours.
On that final day, we were all invited to listen to a natural concert – the so-called Sound of Silence – where we each put down our phones and cameras, and even the ship’s engine went quiet. The calm waters respected the natural symphony and joined us almost in stillness, with the waves and winds only at a whisper. I listened to the melody of a single, distant waterfall and the strumming of rain upon the deck. This was peace, or as close to it as I have experienced.
And then, the sun descended as our route switched directions, and guests’ excited murmuring and motions returned. The brightly humming engine serenaded us into the night.

REALNZ DOUBTFUL SOUND OVERNIGHT CRUISE FAQ
Best time of year to visit Doubtful Sound
Autumn (March to May) is a special time in New Zealand in general, since the Autumn leaves bring a little seasonal much of the country’s woodland. However, in Fiordland, many of the trees are evergreen. No matter – Autumn brings mild weather to Fiordland, although things begin to cool down towards the end of the season.
Summer (Dec to Feb) is the best time if you want sunny weather, late evenings, and less chance of rain and wind. (Though, in Fiordland, you might have rainy weather at any time of year!) Temperatures can reach up to 30 degrees Celcius / 80 degrees Fahrenheit, so it’s a great time to take a dip in Te Anau Lake during your trip to Fiordland!
Spring (March to May), while pleasant in much of the country, brings unsettled weather to Doubtful Sound, with high chances of wind or rain. On the bright side, you’ll see vibrant wildflowers and, if you’re planning Fiordland as just one stop on your itinerary, it’s a great time to visit NZ in general, with cute lambs frolicking around the fields and cherry blossoms blooming.
Winter (June to August) is an epic time to visit Fiordland, as long as you don’t mind the cold and shorter days! The weather is more settled than usual, with snow topping the mountains. If you’re very lucky, like me, you’ll even get to see it snow in Doubtful Sound! Very occasionally, the Wilmot Pass is closed to high levels of snowfall or flooding, when cruises are cancelled. I adored my Winter Doubtful Sound cruise, and don’t think I’d change my experience for the world.
What to pack for Doubtful Sound overnight cruises
In the summer, bring shades, a sun hat and sunscreen and in Winter, you’ll definitely need a warm winter coat, layers, and a hat and gloves. (I had proper ski gloves with me as I get cold easily.)
At any time of year, you’ll need a raincoat. Doubtful Sound receives, on average, 3000-6000 millimetres of rainfall a year!
I recommend bringing a warm layer even in summer as the weather is unpredictable. Bring comfy shoes as the deck could get slippy if it rains, and don’t forget a reusable water bottle. (This is the filter water bottle I use for travel – use my discount code HAG15 for 15% off!)
Also bring a comfortable change of clothing, personal toiletries and overnight clothes such as pyjamas, insect repellent, cash for the bar, and a camera. Oh, and swimwear… just in case. Trust me.
How big is Doubtful Sound?
Doubtful Sound is 421m deep and 40km long, making it the deepest and second longest fiord in South Island.
Why is it called Doubtful Sound?
Back in 1770, Captain Cook named it ‘Doubtful Harbour.’ He actually didn’t enter the inlet he saw from the ocean, as he wasn’t sure if he would be able to navigate it via sailing.
In later years, it was renamed ‘Doubtful Sound’ by whalers and sealers.
Interestingly, Doubtful Sound is not a Sound at all, but a Fiord. A Fiord is a deep and narrow sea inlet, usually characterised by long corridors of water flanked by high cliffs. Fiords were originally formed by glaciers.
What is Doubtful Sound’s Māori name?
Doubtful Sound’s Māori name is Patea. Patea aptly translates to ‘the place of silence,’ and to this day remains free of noise pollution, staying true to its peaceful name.
Is Doubtful Sound worth visiting?
Yes, Doubtful Sound is absolutely worth visiting! From the magical sights and abundance of wildlife to the memorable experience of staying on board a ship, this is one of the absolute best things you can do on the South Island.
In the two and a half years I lived in New Zealand, this is the best thing I did alongside volunteering at an animal sanctuary.

This looks like an incredible cruise. I’d love a few days to explore this area.
What a location! It sounds so amazing to stay overnight. This trip went straight in my bucket list. And thanks for explaining where the name comes from!
