Milford Sound Observatory

The Milford Sound Discovery Centre and Underwater Observatory offers a unique view of this magical part of New Zealand and enhances your Milford Sound experience. Find out about visiting the Milford Sound observatory.

Milford Sound is home to New Zealand’s only floating underwater observatory. Here you can get a unique view of the fascinating underwater environment, without getting wet!

Walk down the steps into the large underwater viewing room and find yourself 10 metres below sea level, in air conditioned comfort. See the colourful sea life up close and discover the species of black coral usually found at depths of 500 metres in the open ocean. Gaze at the fish and other wildlife – it’s just like visiting an aquarium, except the exhibits are roaming free and you’re the one in the enclosure!
