Milford Sound / Piopiotahi
The eighth wonder of the world: sheer granite cliffs plunging thousands of feet into primordial waters.
Geographic Essence & What Makes It Unique
Described by Rudyard Kipling as the "eighth wonder of the world," Piopiotahi / Milford Sound is the crown jewel of Fiordland National Park. Carved by gargantuan ice age glaciers, its sheer granite walls ascend nearly straight out of the dark, tannin-stained sea waters up to 1,200 meters into passing clouds. During Fiordland's legendary downpours—receiving up to seven meters of rain annually—hundreds of temporary waterfalls sprout instantly along the cliff faces, blown upward by oceanic gusts.
