Milford Sound

Milford Sound, known in Maori as Piopiotahi, is a fiord in Fiordland National Park on the southwest coast of New Zealand's South Island, formed by glacial erosion and fed by the Cleddau, Arthur and Harrison rivers before opening into the Tasman Sea. It runs about 15.1 kilometers long, up to 1.94 kilometers wide and reaches a maximum depth of 291 meters over a surface area of roughly 25 square kilometers. Despite its name, geologists classify it as a true fiord rather than a sound, and it is New Zealand's best-known tourist destination, voted the world's top travel destination in TripAdvisor's 2008 Travelers' Choice awards; the writer Rudyard Kipling famously called it the eighth Wonder of the World.
