Milford Sound Underwater Observatory - Southern Discoveries

Very cool spot. We didn’t get to see too many fish/wildlife but it was a great educational experience.

Only an extra $20 from the cruise ticket. It adds an additional hour to the tour but this is good value if you love science. The instructor is very informative and passionate about the area. Very engaging with the audience

It really is worth booking with the boat company that offers the underwater observatory as part of their cruise. Make sure you do read what company you book with as only ONE company is permitted to stop and let you explore this really unique experience. It’s called “Southern Discoveries” So much information to read and really amazing to see the conditions that allows this deep sea coral to grow so close to the waters surface. The whole complex of buildings are floating and connected to the mainland with some very cool engineering too, worth seeing from the back walkway

Small but well created/ maintained floating observatory 10 meters below the lake. We got an opportunity to see various types of fishes, corals etc. The guide was amazing as well informing us about the rich flora and fauna quite unique to milford and how it is preserved. It's worth a visit if you are visiting milford sound.

Good experience but alot of your viewing might depend on luck and when the fishes come. Please note it is not an aquarium, it is an oberservatory so don't expect to see sharks or massive marine life

We did Milford Sound cruise tour and they dropped off us at underwater observation. I didn’t even know this place was included on our tour. But I really enjoyed the experience here. The tour guide was very knowledgeable and friendly. Highly recommend this place.

Pretty cool. Lots of information to read. Take note: It's not an aquarium, it's an observatory so what you see depends on the day, there's no guarantee.

A must see. Plenty of information boards and as we were there on a clear day lots of fish to see. Would have liked longer in the viewing area. The time went very quickly. Spent more time in the waiting area.
