Visit Milford Sound Observatory | New Zealand’s Only Floating Underwater Observatory

Milford Sound is home to many natural wonders including glacial fiords dating back to the Ice Age, lush rainforests formed from being the wettest place in New Zealand, and one of the wettest in the world, and even rare endangered species like Fiordland-crested penguins. But what truly takes the crown is its unique marine ecosystem. Here you can step 10 feet underwater without getting a drop on yourself at Milford Sound’s Underwater Observatory.

What is the Milford Sound Underwater Observatory?

This observatory at Milford Sound is New Zealand’s only floating underwater observatory. Accessible only by boat, you can witness Milford Sound’s deep-water emergence where freshwater meets saltwater from the sea.

This is also your ticket to surround yourself with Milford Sound’s inky black water.

Black Coral forests

Imagine an underwater gothic wonderland. Towering black coral, centuries old, weaves intricate forests that shelter a kaleidoscope of marine life. Keep your eyes peeled for shy shrimp, playful fish darting between branches, and maybe even a curious penguin peeking in.

History of Milford Sound Underwater Observatory

Milford Sound, 1989, marked the emergence of a dream. John Roberts, a local visionary, envisioned an underwater observatory beneath the turquoise surface. Undeterred by skepticism and budget constraints, John's passion for the fiord's hidden wonders propelled him forward. Five years later, in 1994, his dream materialized as the world's first floating underwater observatory opened its hatches, unveiling the mesmerizing kaleidoscope of life below. Milford Sound's once-secret world was revealed, and John earned his place as a local legend, forever known as "Aquajohn."

Delve deeper into the observatory's offerings, discovering a piece of the legendary 1968 shipwreck "Wahine" amidst the exhibits. Fast forward to 2017, when the Milford Sound Discovery Centre merged with the observatory, creating a hub for both above- and underwater wonders. As you explore, anticipate future chapters with research labs, underwater art installations, and live-streamed glimpses of the fiord's hidden wonders.

DEFINITELY book the overnight cruise. It was the highlight of our trip to New Zealand. Milford Sound is such a devastatingly beautiful place, and there is something magical about spending a quiet night on the deck of your ship, taking it all in. The cabins were cozy and surprisingly comfortable, and the whole ship leans hard into nautical explorer vibes (it's very fun and very instagrammable, if that's your thing). You get a chance to jump into the fiord too, and you better do it! If you can swim, don't miss the opportunity, it's not even that cold (and the showers are hot- you'll be fine). The food on board was better than expected, there's a bar, and you'll learn a lot of fun facts from your onboard nature guide. There is no cell service or wifi, so warn your loved ones you'll be off the grid before you drive to Milford. Lindzey “LZ” Kobiske, Via Google

I highly recommend the overnight tour staying onboard the Milford Mariner. Our coach driver, Brian, picked us up in Queenstown and dropped us back at our accommodation the following day. Brian had a fantastic attitude, he was very helpful, and shared interesting facts at various points along the way, and also accommodated great photo stops. The experience aboard the Milford Mariner was fantastic. The crew, the meals, the accommodation, and of course the spectacular scenery made this an experience we won’t forget. Thank you again to Brian, our coach driver, your great attitude was appreciated.

Booked an overnight cruise to Milford Sound and the whole experience was so memorable, from start to finish! Our driver, Brandon, was super informative and made our journey to the fiord so pleasant, telling us stories about New Zealand and Fiordland, the driving was really smooth (which for me is already a big plus seeing as the roads can be narrow and steep at times) and he is overall a really nice person. The cruise was also very well organized, the rooms were nice and clean, the activities well planned and Riley and Vivian who guided us through some of the things to do were very friendly and informative. 100% would recommend going to Milford Sound with these guys!

More Information

This overnight cruise through the heart of Fiordland provides astonishing views and the ultimate Milford Sound adventure.

You’ll start by departing from the Milford Sound wharf in the late afternoon before cruising through Milford Sound accompanied by our specialist nature guide. They’ll explain the history and geology of the area and be on hand to answer your questions.

This cruise style is relaxed, allowing plenty of time to view the fiord’s spectacular waterfalls, rainforest, mountains and wildlife – you’re bound to encounter seals and, if you’re lucky, maybe dolphins and penguins too.

The Milford Mariner then anchors in a sheltered cove. From here you can join the guide and explore in the vessel’s tender craft (small boat) or kayaks. If you prefer, you can simply relax on deck and soak in the beauty of this amazing place. If you’re feeling brave there’s always the option of a refreshing swim too. All activities are weather dependent. 

As evening falls, you’ll enjoy a delicious carvery buffet in the dining saloon – a feast prepared freshly by our on-site chef. Then it’s time to relax in the company of your fellow traveller, indulge in some star-gazing and story-sharing or simply retire to your private cabin.

The next day you’ll be able to dig into a hearty breakfast before heading back out to the Tasman Sea (weather permitting) and exploring more of the fiord.

Is it worth going to Milford/Doubtful Sounds on a wet day?

Many say you have not seen Fiordland unless you have seen it in the rain.  When it rains in Fiordland the landscape is dramatic - rock faces stream with waterfalls, mist hangs around the tops of the mountains and rivers and streams rage.  From a dry comfortable vantage point on the bus or boat, this landscape is spectacular for sightseeing.

While we cannot guarantee you will see wildlife, sightings of fur seals are reasonably common in both Doubtful and Milford Sounds.  A pod of bottlenose dolphins resides in Doubtful Sound so you have a good chance of seeing these fascinating mammals, and in Milford Sound dolphins are occasional visitors.  In both sounds the rare Fiordland crested penguin can at times be observed.

How much luggage can I take on my overnight cruise?

We recommend each passenger brings no more than a carry-on sized bag due to space restrictions in the cabins. For a list of what to bring please see the 'more info' section or your booking confirmation.

There is limited luggage storage available at the Milford Sound Visitor Terminal.

What is the difference between a double room and a twin room?

A double room is a private room for two people, with one bed to share. A twin room is a private room for two people, with two single beds.

Your travel agent or the outlet where you purchased your Milford Sound trip will refund the flight component of your ticket.  You will return to Queenstown by  coach.

What is the difference between Milford and Doubtful Sounds?

Our places. Our experiences. Milford and Doubtful Sounds, NZ.

Milford Sound at the mountainous north end of Fiordland National Park is the classic fiord - a deep water inlet between steep sided high mountains.  Milford Sound is a middle-sized fiord at around 13 kms in length and it is famous for its dramatic scenery, especially Mitre Peak.  This fiord is the most accessible of Fiordland National Park’s 14 fiords and it can be reached by bus, car or flight connections from Queenstown.

Doubtful Sound is located in the heart of Fiordland National Park where the mountains are still very impressive but not as high as Milford Sound.  Doubtful Sound is three times longer and  has a sea surface area roughly ten times larger than Milford Sound.  Its three arms are Hall, Crooked and First Arm.  It is famous for its wilderness scenery and wildlife sightings.  To get to Doubtful Sound visitors first take a launch trip across Lake Manapouri and drive over Wilmot Pass.

Visitors with enough time choose to visit both fiords as they have different characters.

What are the driving conditions to Milford like in the winter?

Driving conditions during winter (May to September) can be difficult.  Extreme care is needed as freezing temperatures mean the road can ice over in shaded places.  During the winter it is  mandatory  to carry snow chains in your vehicle as the road can sometimes be covered in snow.  These are available for hire from petrol stations in Te Anau and Queenstown.

If you are not confident about driving in winter conditions then take a RealNZ  coach  to Milford Sound so you can relax and take in the stunning scenery.

Throughout Fiordland the fiords are officially mapped as sounds.  Strictly speaking, they should be called fiords.

A fiord is a glaciated valley - typically narrow and steep-sided - that has been flooded by the sea after the glacier’s retreat.  A sound, on the other hand, is a river valley flooded by the sea following a rise in sea levels or depression of the land, or a combination of both.

Online transactions/prices are conducted in what currency?

All prices and transactions on the RealNZ website are in New Zealand dollars (NZD).  This is specified on the Terms & Conditions page.

What happens if there is an emergency?

Our staff are trained to deal with incidents and in case of an emergency you should listen to their instructions. We have a portable defibrillator on each of our overnight cruise vessels (Milford Mariner, Milford Wanderer and Fiordland Navigator). In addition to this we also have portable defibrillators at the following locations: •    Milford Sound Visitor Terminal •    RealNZ Visitor Centre, Manapouri •    Cavern House (Te Anau Glowworm Caves) •    Colonel’s Homestead Restaurant, Walter Peak •    TSS Earnslaw Vintage Steamship •    Stewart Island Ferry (Bluff - Oban - Bluff)

Can my dietary requirements be accommodated? 

Yes, dietary requirements can be catered for. Please provide detailed information regarding your dietary requirements when making a booking. 

Is the boat accessible for individuals with impaired mobility? 

When we are informed in advance about guests with hindered mobility, we make every effort to mitigate the impact by assigning rooms in proximity to the main areas. However, it’s important to note that our vessels are not optimally equipped for potential needs. While we extend a warm welcome to individuals with impaired mobility, all our vessel’s doorways feature a sea sill, there are no ramps within the boat, and a flight of stairs separates rooms from the main saloon.
