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.

I had been out kayaking the day prior and was not sure it was worth it to come all the way back out for the cruise. It was totally worth it! Stunning views, super comfy boat, lovely crew (didn't get his name but your guy from British Columbia is fabulous! However. Things they don't tell you (or I missed) you have to pay to park which is kind of baloney when you have no other option. Or there is an option to park out and walk in about 30 min, but no way to know that until I asked someone at check in. Also make sure you leave enough time to walk around the harbor from the paid parking to the boats. I arrived 15 minutes early as instructed and almost didn't make it

I really liked the Mitre Peak's boat. We were not too many on it and thanks to its size, we could get very close from the falls. The crew was nice and having hot drinks available is a big plus!

Best part of our NZ trip, hands down. Our guide, Steve, was funny and super chill. He let us stop for extra pics when the road was clear. The cruise part was honestly magical—I’ve never seen water that blue. Boat wasn’t too packed, maybe cuz we went early. Bring snacks, the food sells out FAST.
