This iron-rich hot spring lies on the West Coast of New Zealand's South Island, a region known for its wild landscapes and heavy rainfall. The water emerges at around 36 °C, tinted by its high iron content.
Insider tip — The West Coast of New Zealand's South Island between the Franz Josef Glacier and Hokitika is a narrow ribbon of temperate rainforest — one of the world's wettest inhabited coastlines, where ancient rimu and kahikatea forests meet glaciers descending from the Southern Alps. Iron-rich springs emerge from the ancient Alpine Fault geology of this isolated coast, where the Pacific and Australian plates collide to build both the Southern Alps and the geothermal conditions for mineral spring formation in the rainforest.
