Milford Sound is a fjord in the south west of New Zealand's South Island, within Fiordland National Park and the Te Wahipounamu World Heritage site.

Milford Sound was initially overlooked by European explorers, because its narrow entry did not appear to lead into such large interior bays. Sailing ship captains such as James Cook, who bypassed Milford Sound on his journeys for just this reason, also feared venturing too close to the steep mountainsides, afraid that wind conditions would prevent escape (this refers to Doubtful Sound, so named as Cook thought it doubtful he would escape if he sailed in).

The fjord was a playground for local Maori who had acquired a large amount of local marine knowledge including tidal patterns and fish feeding patterns over generations prior to european arrival. The fjord remained undiscovered by Europeans until a sealer by the name of Captain John Grono discovered it in around 1812 and named it Milford Haven after his homeland in Wales. Captain John Lort Stokes later renamed Milford Haven as Milford Sound.


By road, Milford Sound is 307;km from Queenstown and 279 km from Invercargill (about four hours' drive), with most of the tour buses to the sound departing from Queenstown. Some tourists also arrive from the smaller tourism centre of Te Anau, 121 km away. There are also scenic flights by light aircraft and helicopter tours to and from Milford Sound Airport. The drive to Milford Sound itself passes through unspoiled mountain landscapes before entering the 1.2 km Homer Tunnel which emerges into rain-forest-carpeted canyons that descend to the sound. The winding mountain road, while of high standards, is very prone to avalanches and closures during the winter half of the year.
