Actually a fiord rather than a sound as its name might suggest, Milford Sound was formed by the erosive effects of a glacier. This is as opposed to a sound which is a river formed valley which has been flooded by the sea.
It is the only fiord accessible by road, along a stunning alpine drive through unspoiled mountain landscapes. Despite its accessibility, the remoteness and rugged beauty of Milford Sound is bounded by steep cliffs, dense rainforest and remains tranquil.
Running 15 kilometres inland from the Tasman Sea, the sound is surrounded by mountains that reach up to 1512 metres high. One that resembles an elephant's head and the other a crouching tiger are two of the tallest peaks.
Relax on an unforgettable overnight cruise in the heart of Milford Sound and wake up to some of the most stunning natural scenery in the world. You’ll pass cascading waterfalls, majestic mountains and lush rainforest. Don't forget to keep your eyes peeled for resident dolphins, rare penguins and look below the waters as these mountains plunge to the floor where an underwater world exists.
