Milford Sound is on the west coast of the south island of New Zealand. For the most part only 2 things happen in Milford Sound, 1) fishing (Lobster I think), 2) tourism. The water has a lot of aquatic life including dolphins, seals, as well as the expected fishes etc. My dolphin and seal pictures didn't really come out well, so you'll have to put up with the waterfall series instead. The entire inlet is surrounded by these mountains coming straight out of the water. These water falls aren't constant, they allegedly turn on and off quite quickly depending on if it's just rained or not.
