'Milford Sound (Piopiotahi in Māori) is a fjord in the south west of New Zealand's South Island, within Fiordland National Park, Piopiotahi (Milford Sound) Marine Reserve, and the Te Wahipounamu World Heritage site. It has been judged the world's top travel destination in an international survey (the 2008 Travelers' Choice Destinations Awards by TripAdvisor) and is acclaimed as New Zealand's most famous tourist destination. Rudyard Kipling had previously called it the eighth Wonder of the World.
Milford Sound was initially overlooked by European explorers, because its narrow entry did not appear to lead into such large interior bays. James Cook bypassed Milford Sound on his journeys for just this reason. The fjord remained undiscovered by Europeans until Captain John Grono discovered it c.1812 and named it Milford Haven after his homeland in Wales.' (Wikipedia)
