Milford Sound — Piopiotahi (Fiordland)
Iconic fjord of Fiordland National Park (South Island), at the heart of Te Wāhipounamu UNESCO-inscribed in 1990 (2.6 million hectares, one of the last intact Gondwana reserves on Earth). The fjord stretches 15 km from the Tasman Sea inland, dominated by Mitre Peak (1,692 m) plunging straight into the water, lined by towering waterfalls (Stirling Falls 151 m, Bowen Falls 162 m). Daily cruises (2 h, ~NZ$100-150) from Milford Sound Village, accessible from Te Anau via the spectacular SH94 road (118 km, ~2 h, must-drive with stops at Mirror Lakes, The Chasm, Homer Tunnel 1,270 m).
Rudyard Kipling famously called Milford Sound the « eighth wonder of the world » during his visit in 1891. Technically, it's NOT a sound (drowned river estuary) but a FJORD (drowned glacial valley) — the misclassification dates back to 19th-century British cartographers. Rainfall reaches 6,800 mm/year (one of the wettest inhabited places on Earth), which explains the proliferation of temporary waterfalls after every rain — cruising in the rain is actually spectacular. The fjord was carved by Pleistocene glaciers between 100,000 and 20,000 years ago, reaching depths of 291 m. Whales, Hector's dolphins and fur seals are frequently observed.
