Milford Sound is a world-famous natural wonder. It is formed by the force of glaciers and enjoys the reputation of “the eighth wonder of the world”. It is located on a glacial terrain within the Fiordland National Park in the southwest of New Zealand's South Island. The cliffs, emerged from the calm and dark waters, are steep and winding, with dense rainforests on the cliffs. And waterfalls plunge into the sea from hundreds of meters high over the cliffs. The water tour of Milford Sound is the main way to enjoy the fjord's beauty. Seals, dolphins, the downpours all year round and the mists all adds to its beauty. Surrounded by hills covered with snow, there are many small waterfalls formed by snow melting.
