Hidden under the surface in Harrison Cove is a unique and beautiful environment – there’s nowhere else in the world quite like it. In the middle of Piopiotahi Marine Reserve, the Underwater Observatory enables you to experience the magic of this special world, previously the exclusive realm of divers.
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; it’s the people who are contained.
