This may sound like a strange thing to do in waters well away from the coral reefs of the tropics, but Fiordland (including Milford Sound) has some very unique marine life found only in this area.

The high rainfall of fiordland leaches out tannins from the vegetation which flows down rivers and steams into the fiord resulting in a tannin-stained freshwater layer which lies on top of the salt water below. This tannin-stained freshwater layer filters out light providing a unique environment for marine life that is normally found in deeper water (approx 80-100metres) to occur much closer to the surface (10-20 metres).

Once below the freshwater surface layer you enter the warmer salt water environment where the marine life begins. Black and red corals, sponges and colourful anenomes are just some of the unique marine species you will encounter.

A wide variety of fish species keep divers company, with an occasional crayfish popping out for a look from under their rocky homes. Dolphins and seals are common sights in the fiord, and if you are very lucky you may have a chance encounter with a Fiordland Crested Penguin which visit these water seasonally.

All divers must have completed a recognized dive course and have a dive card or proof of completing a course before they will be accepted on a trip. All gear can be hired and if you have a non diving member of your party they are more than welcome to come along and experience the above water scenery. If they are really keen snorkeling gear can be hired so they don't feel like they have missed out on this truly unique underwater environment.
