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.

Read on to learn all about the underwater observatory at Milford Sound, what to expect, and other important information to make your visit seamless.

What is the Milford Sound Underwater Observatory?

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

Highlights of Milford Sound Underwater Observatory— your underwater safari

Ready to trade mountain peaks for coral castles? Dive beneath the waves at the Milford Sound Observatory and witness a hidden realm teeming with fascinating creatures and otherworldly landscapes. Here's a sneak peek at the underwater treasures you can expect:

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.

Loved the kiwi humour. Very relaxed but actually very efficient too. Everyone was determinedly positive through the rain. Crews cared for us really well. Instructions were clear, polite but definite. Bus drive ( which l thought would be the boring bit ) was very entertaining and informative. Lots of opportunities to take photos. Scenery was magnificent and loved getting to the sea.

The trip was lovely. Traveling on a catamaran is smoother than on a ship with a bow. The staff were very friendly and attentive, thank you. One important note: the captain provided lots of interesting explanations. As the organizer, please note that these cannot always be translated in a way that is understandable to an international audience. An audio guide would be useful and important!

The views were incredible. There is no way to fully understand the majestic peaks and landscape but from the air! So much is unreachable. Andrew our pilot was fabulous. We felt very safe and surprisingly the helicopter was so calm whilst flying. We did have the most glorious day! The landing on the glacier cliff face was beyond wild! It looked impossible but was actually flat where we landed. That was amazing!!!! Lifetime memory stored away now
