Milford Sound Underwater Observatory - Southern Discoveries

Hidden under the surface of Harrison Cove is a unique and beautiful environment - there's nowhere else in the world quite like it. Thanks to its unique deep water emergence phemomenon, Milford Sound is home to species of black coral usually only found at depths of more than 500 metres. Descend 64 steps (10 metres) underwater into a large, fully air-conditioned viewing area where large windows with excellent optical clarity open your eyes to this deep underwater haven. Unlike an aquarium, the fish are free to come and go.
